+
+unix/hlib/install

+	the unix local/bin.  (5/16)
+

+	1. Modified DECstation/IRAF to change the architecture name from "mips"
+	to "dsux".  Anyone having IRAFARCH defined in their environment as
+	"mips" will have to change it to "dsux" to run IRAF.
+	2. A couple of the files in OS were modified to change #ifdef mips
+	constructs to also check for #ifdef ultrix.  If both mips and ultrix
+	are defined it is a DECstation, otherwise at present we will assume
+	the OS is umips.  (5/27)
+

+noao/mkpkg
+	Modified so that the same mkpkg file can be used for DSUX and MIPS
+	systems without change.  (5/27)

+	Renamed the notes file for the DECstation port.  (5/28)
+
+sys/mwcs/README		+
+	Added a README file to MWCS, containing an interface summary.  (6/5)
+
+sys/mwcs/iwewcs.x
+	The code which computes CRPIX when reconstructing the Wterm from a
+	FITS header was optimized with a "if (have_ltv)" but this was
+	incorrect, since the computation uses both the LTV and LTM portions
+	of the Lterm (hence it is necessary to test have_ltm as well).
+	The result was that, given an Lterm consisting of only a scale term
+	and no shift, the code could fail to restore the correct Wterm
+	reference pixel coordinate.  (6/7)
+
+dev/termcap	[tucana, orion, gemini]
+	Added Rob's 3 two-column landscape mode printer entries.  (6/12/90 SRo)
+
+*
+	Removed world write permission from all iraf files.  Only a few were
+	affected, but there were a few files and directories that happened
+	to have world write perm, and none should (too easy for users to
+	delete or modify files, accidentally or otherwise).  (6/18)
+
+pkg/softools/mkttydata.hlp
+	Deleted the explicit instructions for performing a sysgen-relink,
+	which are no longer applicable to all versions of IRAF, and added
+	comments to the affect that use of MKTTYDATA to cache termcap or
+	graphcap entries is inadvisable for most sites.  (6/19)
+
+sys/qpoe/QPOE.hlp
+	Revised and updated the section on QPEX; the documentation for this
+	section was out of date.  (6/20)
+
+lib/syserrmsg
+	Changed the error message for SYS_QPUKNPAR from "attempt to delete a
+	nonexistent parameter" to "unknown parameter".  This message is used
+	for all unknown parameter references, not just parameter deletions.
+	(6/22)
+
+sys/qpoe/qpgpsym.x
+sys/qpoe/qpgmsym.x
+sys/qpoe/qpaccessf.x
+sys/qpoe/README
+	1. The QPOE macro facility supports two kinds of macros, global macros
+	defined in an external QPDEFS type file which affect all QPOE file
+	references, and datafile-local macros defined as "macro" type
+	parameters in the individual QPOE file headers.  There was a problem
+	with the latter feature (datafile-local macros) due to QPOE header
+	parameter references employing full macro expansion.  A routine
+	such as qp_write would perform macro expansion on the parameter name,
+	and if the referenced parameter was the macro parameter itself, one
+	would get the parameter pointed to by the macro alias rather than
+	the macro parameter, making it impossible to access macro parameters
+	once defined.  The solution adopted was to disable expansion of
+	datafile-local macros in low level header parameter accesses.
+	Datafile-local macros are still used in expressions, hence can be
+	used to define things like event struct fields names.  Also, global
+	macros are still used in header parameter accesses, hence header
+	parameters may still be aliased using global defines.
+
+	2. The routine qp_expandtext was reclassed as an interface routine
+	instead of an internal routine.  If aliasing of header parameters
+	using datafile-local macro parameters is desired, this routine may
+	be called to conditionally translate the parameter name before
+	accessing the parameter, allowing the name to be aliased.  (6/24)
+
+unix/boot/rtar/rtar.c
+unix/boot/rtar/rtar.hlp
+	Added two new switches to RTAR.
+
+		-m	Do not restore the file modify times.
+		-u	Do not attempt to reset the user and group ids.
+	(6/25)
+
+sys/qpoe/qpclose.x
+	A qp_open to create a new qpoe file followed immediately by a qp_close
+	would create a file with no qpoe file header descriptor, causing an
+	error when the file was subsequently opened with qp_open.  qp_close
+	was checking for the case of an open/close with no header writes and
+	was forcing a qp_bind in this case, but the QP_MODIFIED flag was zero
+	so the file header was not being updated.  Added a QP_MODIFIED(qp)=YES
+	to force the file header to be updated, if qp_close is called on a
+	new qpoe file before any header modifications have been made.  (6/26)
+
+sys/gio/imdkern/imdopen.x
+sys/gio/imdkern/imdopenws.x
+	The imd_openws routine in the new IMD kernel was given a calling
+	sequence of imd_openws(devname,n,frame,color,mode) when the kernel
+	was first written.  However, this routine is one of the externally
+	callable driver routines and the calling sequence is fixed as defined
+	by the GKI interface (the calling sequence must be the same for all
+	GIO kernels).  The IMD kernel will work fine when run standalone,
+	but could die on a segmentation violation when called as a GIO
+	subkernel, since the subkernel interface is GKI.  By chance this
+	escaped all our testing, as the argument list mismatch can easily
+	go undetected, depending upon the chance contents of the registers
+	or stack locations associated with the missing input arguments.  (7/1)
+
+unix/hlib/mkiraf.csh
+	Modified the unix/iraf mkiraf script to prevent the user from running
+	mkiraf in an iraf system directory (any iraf directory other than
+	iraf/local).  (7/5)
+
+unix/hlib/mkpkg.inc
+unix/shlib/edsym.c
+	1. In the tucana/irafx mkpkg.inc, deleted the -T from the default
+	link flags to allow editing of shared image symbols.
+
+	2. When shared image versions were added a while back I forgot
+	to add version support to EDSYM, the symbol table editor.  The
+	program has been modified to examine the text segment of the
+	file being edited to determine the shared library version number,
+	and use this to access the correct shared image (e.g., S5.e is
+	the version 5 shared image).  With these changes, executables
+	linked in the default way will again have the correct symbols
+	for the shared image (allowing use of adb or dbx to examine
+	locations in the shared image, without having to relink -z).  (7/5)
+
+unix/boot/spp/xc.c
+	Modified XC to automatically disable the call to EDSYM (the symbol
+	table editor) when linking a host program (xc -h).  (7/6)
+
+sys/imfort/mkpkg
+sys/imfort/imfparse.x
+sys/imfort/imfmkpfn.x
+sys/imfort/imftrans.x			+
+	1. Due to the use of vfn_translate in imfparse.x, the directory prefix
+	field, if any, of the image name was being discarded.  This would
+	prevent use of IMFORT to access images other than in the current
+	directory.  The use of vfn_translate was inadvisable in any case,
+	as it performs more VFN translation than is desired, and IMFORT is
+	supposed to allow unrestricted use of host filenames.  The fix was
+	to replace the call to vfn_translate by a call to a new internal
+	imfort routine imf_trans.  This will still do a very limited amount
+	of escape sequence encoding on the image filename, allowing mixed
+	case and multiple "." delimited fields to be input and translated
+	as for IRAF vfns, e.g., on VMS.  Since such filenames are not legal
+	in VMS (mixed case is legal but is not very useful in VMS) this
+	level of translation should be fairly safe.
+
+	This was introduced into V2.9 on 11/28/89 (when the IMFORT pixel-file-
+	clobber bug was fixed).  It is surprising that the problem was not
+	reported earlier.  Most people must access only images in the current
+	directory.  (7/6)
+
+	2. The call to vfn_encode in imf_parse was not quite right either.
+	vfn_encode only returns the next field of a pathname, and when
+	imf_parse was called with a path and a non-image 3 char extension,
+	part of the path would be lost.  The solution was to replace the
+	call to vfn_encode by a call to the new imf_trans routine, which
+	avoids just this problem.  (7/9)
+
+dev/hosts	[tucana, orion, gemini]
+	Changed cmd field for draco, to use known object "241", which
+	currently points at usr$0:[rooke]irafks.com, but will shortly
+	point to usr$3:[irafext.kpnolocal.src.dni]irafks.com.  (7/12 SRo)
+
+dev/graphcap	[tucana, orion, gemini]
+	Added iism70d field for draco-hosted iis, aliased to iism70c & iism70l
+	for backward compatibility.  Changed DD in default iism70 entry to
+	point to draco, using iia0, as we currently have no UNIX-hosted iis.
+	(7/12 SRo)
+
+unix/os/zmain.c
+unix/os/zzsetk.c
+unix/os/zfiopr.c
+	Added a new facility to UNIX/IRAF for debugging interprocess
+	communication (IPC).  This feature will also be useful for debugging
+	tasks standalone, particularly in cases where a bug seen when the
+	task is run from the CL is difficult to reproduce when the task
+	is run standalone.
+
+	The facility is this: if LOGIPC is defined in the host environment
+	when an iraf process is started, the process will create two files
+	PID.in and PID.out, where PID is the process id.  Everything read
+	from the IPC input file is copied to the .in file, and everything
+	written to the IPC output (e.g., sent back to the CL) is copied to
+	the .out file.  This is done only for connected subprocesses.
+	It will work for any connected subprocess, e.g., normal cached
+	processes and graphics subkernels in both foreground and background
+	CLs, but not the i/o of the CL itself since it is not driven by IPC.
+
+	The IPC streams saved are an exact binary copy of whatever was sent
+	via IPC, including the binary IPC packet headers, binary graphics
+	data, etc.  However, most IPC traffic is textual in nature, so it
+	will usually be possible to read the IPC files with a file pager,
+	or even "cat" them to the screen (not avisable if graphics data is
+	involved).
+
+	A particularly interesting use of this feature is to allow a process
+	to be run under the CL in the normal fashion, then rerun under the
+	debugger using the saved IPC input to duplicate the input and actions
+	of the process when run under the CL.  For example:
+
+		% setenv LOGIPC
+		% cl
+		cl> dir
+		cl> logout
+		% unsetenv LOGIPC
+
+	Will run the CL, saving the IPC of all subprocesses (x_system.e).
+	We can then run the system process manually, using the saved IPC
+	input:
+
+		% $iraf/bin/x_system.e -c < PID.in
+
+	To run the process under ADB or DBX, using the saved input:
+
+		% adb $iraf/bin/x_system.e
+		:r <PID.in -c
+	or
+		% dbx $iraf/bin/x_system.e
+		dbx> r -c < PID.in
+
+	Note that the redirection has to be given first for ADB, and last
+	for DBX.  [In recent versions of SunOS there must be no space after
+	the "<" in the :r command to adb.]
+
+	Running a task in this way is not identical to running the task
+	standalone, e.g. using a DPARAM file for parameter input, because
+	the exact runtime context of the process as run under the CL is
+	reproduced.  The differences are subtle but can be important when
+	trying to reproduce a bug seen when the process is run under the
+	CL.  For example, the functioning of the task is slightly differenct
+	when the -c flag is used, the environment is passed in via IPC rather
+	than being read from hlib$zzsetenv.def, and so on.  Except for
+	possible kernel level differences associated with spawning the
+	process by forking a shell rather than the CL, the process should
+	execute identically as it did under the CL.  (7/17)
+
+sys/vops/amov.gx
+	This routine could fail, corrupting the data array, in some
+	cases when the input and output arrays overlap.  The same
+	problem exists in standard V2.9 iraf except that in most iraf
+	implementations, a host optimized version of AMOV is used,
+	hence the bug has not been seen.  (7/19)
+
+sys/imfort/tasks/pcube.f
+	This file contained a subroutine containing the following sequence of
+	statements (irrelevant statements ommitted):
+
+		subroutine pcuber (pix, nx,ny,nz, i1,i2, j1,j2, k1,k2)
+		real	pix(nx,ny,nz)
+		integer	nx, ny, nz
+
+	On the MIPS, this produced a warning about nx/ny/nz already having
+	been declared.  Probably when the compiler processes the REAL
+	statement it assumes the parameters are type integer.  This seems
+	reasonable, so I moved the INTEGER card up before the REAL and the
+	warning went away.  (7/19)
+
+sys/imfort/tasks/mkim.f
+	This task creates a test image where the pixel value is computed based
+	on the position of the pixel in the image.  The relation being used
+	was (j*ncols+i), which is the pixel number starting at [1,1], except
+	that the value is offset by a line, which is ok but not what one would
+	expect.  I changed it to ((j-1)*ncols+i).  (7/19)
+
+vms/hlib/sigqueue.com
+	Added qualifiers /passall/nofeed to the ln03 print command.  (7/20 ShJ)
+
+pkg/utilities/doc/polyfit.hlp
+	Added the missing "statistical" heading under the weighting section
+	in the polyfit task help page. (7/23/90 LED)
+
+sys/plio/pllpr.x
+sys/plio/pllnext.x
+sys/plio/pll2r.gx
+sys/plio/pll2p.gx
+sys/plio/plcmpress.x
+	These files each contained statements of the form
+
+		(foo * I_SHIFT) + goo
+
+	where foo is type short and I_SHIFT is an integer constant.  The VMS
+	Fortran compiler, due to a misfeature or otherwise, evaluates a short
+	times an integer literal using short integer arithmetic, causing
+	integer overflow in the short integer intermediate expression.  The
+	solution adopted was to replace the "foo" in expressions such as the
+	above by "int(foo)".  (7/24)
+
+vms/os/zmain.c
+	The vms/iraf process main was modified to add support for calling
+	iraf tasks on the host system command line, a feature which was added
+	to unix/iraf some time ago.  As with unix/iraf, any extra command
+	line arguments are passed on to the iraf main as the iraf command to
+	be executed.  The vms/iraf version has the additional feature that
+	the process stdin and stdout/stderr may be redirected on the command
+	line, using the usual syntax <file >file >>file.  This is NOT THE
+	SAME as redirecting the i/o of the iraf task, with 4>file etc.
+	arguments to the task.  Both or either form of redirection may be
+	used, but the process main arguments must preceed the command to be
+	passed to the iraf main.  (7/24)
+
+noao/lib/strip.noao
+	Added ONEDSPEC to the list of packages to be stripped; don't know
+	why this was missing.  (7/25)
+
+pkg/utilities/t_curfit.x,curfit.gx
+	Moved the ic_close(rd) calls out of the input file/image loop
+	and into the main routine. The pointer to icfit was being freed
+	after the first file of data was fit and not reallocated before the
+	next fit was initiated resulting in a segmentation violation.
+	(LED 7/30/90)
+
+dev/hosts	[tucana only]
+	Added adonis (engineering hp9000/370) to network for hpux testing.
+	(7/30/90 SRo)
+
+math/gsurfit/gsder.gx,gsderd.x
+	Corrected a typo in the gsder.gx routine which was causing a
+	pointer to be passed to the salloc routine instead of a size.
+	If the pointer addresses became very large this caused
+	an out of memory allocation error. This error has been in existence
+	as long as the package but only showed up on the MIPS.
+	(8/1/90 LED)
+
+sys/imio/iki/oif/oifmkpfn.x
+	Modified to check for the null image, and return "dev$null" as
+	the pixel file name in this case.  (8/4)
+
+unix/boot/spp/xc.c
+	1. All internal system executables called by XC (currently xpp.e,
+	rpp.e, and edsym.e) are now located using the iraf routine
+	os_sysfile, rather than searching through the host system
+	directories /usr/bin, /usr/local/bin, and so on.  This ensures
+	that XC will always find these executables, regardless of where
+	the iraf host level commands xpp, rpp, etc. are installed (XC does
+	not even care if these are installed as user commands, anymore).
+
+	2. The technique used to locate host commands such as f77 and cc
+	was changed to the following sequence: [1] first the directories
+	defined by the user's $PATH are searched (using execvp), [2] the
+	internally defined directory SYSBINDIR is searched (this defaults
+	to /usr/lang on a Sun), [3] the internally defined directory
+	LOCALBINDIR is searched (defaults to /usr/local/bin).
+
+	3. When linking on a Sun/IRAF system, -lI77 is searched only if
+	the old (pre-V1.3) compilers are being used, as I77 has been
+	deleted with the V1.3 compiler.
+
+	The result of the above change for Sun/IRAF is that the revised XC
+	will work with either the new V1.3[.1] compiler, or any of the old
+	compilers.  If both compilers are installed, either may be
+	selected using $PATH.  If the system contains only the new
+	compiler at /usr/lang and the user has not included this directory
+	in their path, XC will still find the compiler.  (8/4)
+
+	NOTE - Although IRAF can now make use of the new V1.3 compilers,
+	these are NOT fully supported yet.  These appear to be largely new
+	compilers.  A new set of system default compiler switches will
+	have to be developed, and the full iraf system recompiled from
+	scratch and tested before the new compilers are fully supported.
+	In particular, note that there is no guarantee that sources
+	compiled with the new compiler will link correctly with iraf
+	objects produced by the old compiler, or that old iraf objects
+	will link properly with the system libraries included with the
+	new compiler.  The default iraf mkpkg compiler switches may not
+	be correct for the new compilers.  Compiler bugs are likely.
+
+unix/boot/spp/xpp/decl.c
+unix/boot/spp/xpp/xppcode.c
+	Modified the code which outputs runtime initialization statements
+	to output these statements after any DATA initialization statements
+	(they were coming out before the DATA statements).  Runtime
+	initialization is used to zero the function value of real and double
+	functions upon procedure entry.  (8/7)
+
+sys/qpoe/README
+sys/qpoe/mkpkg
+sys/qpoe/qpio.h
+sys/qpoe/qpmacro.x
+sys/qpoe/qpoe.h
+sys/qpoe/qpopen.x
+	1. The builtin interface default blocking factor for QPOE was changed
+	from 8 to 1.
+
+	2. The default blocking factor may now be specified individually for
+	each datafile, by defining the optional parameter "defblock" in the
+	QPOE header.   If a datafile default is given this overrides the
+	builtin interface default; any global SET value overrides both,
+	and setting the block factor in the runtime filter expression or
+	in a runtime call to an interface seti routine will override both
+	the datafile and global defaults.
+
+	3. In a related change made while implementing the above feature,
+	qp_open was modified so that interface parameters set in global
+	SET statements (as in QPDEFS) will override datafile parameters
+	inherited from an existing datafile in a NEW_COPY operation.
+	In other words, if the user explicitly specifies a parameter such
+	as "pagesize" or "bucketlen" in their QPDEFS, this will override
+	the default value inherited from an old datafile when a new copy
+	is made.  As before, any runtime qp_seti calls made once the new
+	datafile has been opened will override these defaults.  This was
+	necessary to be consistent with the rule that the most recently
+	specified value for a parameter takes precedence.  (8/8)
+
+pkg/system/directory.x
+	A couple of obscure bugs were fixed which affected unsorted
+	directory listings.  (8/8)
+
+pkg/images/imarith/imasub.gx
+	Fixed a bug in the special path for subtracting an image from
+	the constant zero; i.e. negation via subtraction.  (8/15)
+
+pkg/images/imutil/hedit.x
+	Modified hedit to use the maximum of the default task min_lenuserarea
+	value (28800) and the "min_lenuserarea" environment variable if
+	defined. The previous version always used the default value. (8/15 LED)
+
+dev/graphcap	[tucana, orion]
+	Known object irafks.e is failing due to some problem with its I/O
+	channels at startup time; this happened apparently without any change
+	to VMS or IRAF software.  IIS access via dni from tucana or orion
+	still works if the user has an irafks.com in their login directory.
+	Changed draco!iis to dnidraco!iis, so that the private irafks.com
+	is used.  Will have to fix known object irafks.e later.  (8/17/90 SRo)
+
+pkg/dataio/t2d/t_t2d.x
+	Increased OBUF_PAD, which controls the size of a data record read,
+	from 20000 to 32767 chars.  This value limits the maximum size of
+	an input data record in the tape record, and it is a read error if
+	the actual record is larger.  (Also increased SZ_OBUF to the next
+	larger power of two and increased the max ranges, not that the latter
+	is likely to matter).  (8/22)
+
+dev/uhosts
+	Updated this file to reflect changes in the NOAO internet.  This file 
+	is a modified version of tucana's /etc/hosts file.  (ShJ 8/29)
+
+dev/graphcap
+	Added entries for all colors of imd devices; color indices 202 through
+	217 are now available.  Also added a device "imddicomed" suitable for
+	drawing black, variable width lines destined for dicomed output via
+	the imdkernel.  The imd entry was modified so xs=ys=#0.263, indicating
+	a physically square device.  (8/30 ShJ)
+
+unix/hlib/config.h
+	Changed MT_SZBDEFIBUF (the default maximum input buffer size for
+	magtape i/o) from 32768 to 65535.  This more nearly reflects the
+	maximum record size of most modern devices, and the change was needed
+	to permit the full range of blocking factors for tapes.  (9/3)
+
+unix/os/zfiomt.c
+unix/os/zfiomt.c.BSD            +
+	Installed the temporary "hacked magtape driver" for SunOS, which
+	includes Exabyte support.  This will be replaced shortly in V2.10
+	but is what is being shipped in V2.9.1.  This driver supports the
+	following combinations of devices and host drivers (given the
+	current chaotic situation with tape drivers on Suns it is unlikely
+	that any combinations not tested will work):
+
+	    1/2" reel tape	4.0.3	all except ST (SCSI tape) driver
+	    1/2" reel tape	4.1	untested, but should work
+
+	    Exabyte		4.0.3	Sun ST driver, Ciprico RT driver
+					sparcstation under 4.0.3 not tested
+	    Exabyte		4.1	Sun ST driver, except sparcstation
+
+	1/4" cartridge tape and 1/2" reel tape on the Sun SCSI driver (at
+	least under 4.0.3) is not currently supported.  The Exabyte on the
+	sparcstation version of the ST driver is not currently supported
+	due to serious bugs in the sparcstation version of the ST driver,
+	which is different than any other version of the ST driver.
+
+	The driver automatically determines whether the current system is
+	running 4.0.3 or 4.1 and adjusts it behavior accordingly.  The
+	behavior of the ST driver differs from 4.0.3 to 4.1, and worse,
+	the driver ioctls changed, which prevents magtape code compiled
+	under 4.0.3 from even running on 4.1.  zfiomt works around this
+	by using the hardwired values of the iocts for the two SunOS
+	versions.  (9/3)

+	This file (not part of the runtime iraf system) is a host level
+	magtape test program, which should compile and run on most unix
+	systems.  It is kind of like the unix "mt" program, except that it
+	runs as a command interpreter, allowing one to open a drive and
+	issue a series of commands to exercise the drive.  All the
+	standard driver ioctls are provided, plus commands for reading and
+	writing data records, and various interpreter control commands.
+	The program is useful for exercising drivers (and drives) to
+	determine exactly what they do when the various driver ioctls are
+	issued.
+
+	The following commands are provided:
+
+	    open [device [r|w]]    rewind                   fsf [n]
+	    close                  read [nrec [bufsz]]      fsr [n]
+	    log [file]             write [nrec [bufsz]]     bsf [n]
+	    run <file>             weof                     bsr [n]
+	    verbose                status                   quit
+
+	The "write" command writes records of the given size (default 1024)
+	containing a comment such as "file M, block N" at the beginning of
+	each record.  The "read" command prints out the first 80 printable
+	chars or so of each record read, omitting unprintable chars.  These
+	commands can be used to prepare test tapes and determine to what
+	record the tape is positioned after a given ioctl or command is
+	issued.  (The program is also useful as a crude mtexamine type
+	program).  (9/3)
+
+unix/boot/spp/xc.c		[Sun/IRAF only]
+	The SunOS version of the XC compiler, which makes a stab at trying
+	to support the version 1.3 Sun Fortran and other compilers, was
+	modified as follows:
+
+	    o	When a compile is performed with the new compilers in the
+		path, the compiler runtime BIN directory /usr/lang/SC0.0
+		(or whatever - the path is generated at runtime to reflect
+		whereever the user installed the compiler) is passed as
+		in -L/usr/lang/SC0.0 to the CC command used to link.  This
+		is necessary because the version of CC used to link may be
+		the old C compiler, which will not automatically search
+		the compiler BIN directory /usr/lang.
+
+		The actual library search path specified depends upon
+		whether FLOAT_OPTION is defined in the user environment.
+		For example, if FLOAT_OPTION is defined in the user
+		environment as "ffpa", the search path command line options 
+		will be -L/usr/lang/SC0.0/ffpa -L/usr/lang/SC0.0 (where
+		the user specified path (/usr/lang) and BIN version (SC0.0)
+		are determined automatically at runtime).  Referencing the
+		right version of each library is necessary in order to get
+		the library version optimized for the local floating point
+		hardware on Sun-3s.
+
+	    o	The host libraries searched to link with the 1.3 compilers
+		were changed to -lF77 -lm.  It appears that -lU77 was
+		eliminated in 1.3, as well as the -lI77 noted earlier.
+
+	Using, e.g., f77 to perform the link would avoid the need to have
+	XC know the details of the host libraries but is probably not a
+	workable solution since iraf programs are not Fortran programs
+	("host" programs linked with xc -h are not necessarily Fortran
+	programs either).  f77 would set up the startup files etc.
+	required by f77 programs, whereas an iraf program is to the host
+	system a C program which uses some of the f77 libraries.  If f77
+	could be used to link a C program then it might provide an
+	alternative to having XC know what host libraries to link against,
+	but I doubt if this would work.
+
+	It should be noted that while we are attempting to support the new
+	compilers, full support cannot be expected until the IRAF project
+	begins using these compilers routinely.  (9/3)
+
+	Addendum - Note on 1.3 compilers.  Testing the new XC with the 1.3
+	compilers on a Sun-3, I find that FLOAT_OPTION no longer works as
+	it used to.  If FLOAT_OPTION is defined in the environment and one
+	does, e.g., a cc to compile a file, a message is printed warning that
+	FLOAT_OPTION is being ignored and the the default (fsoft) is being
+	used.  It is necessary to explicitly compile with -f68881 or whatever
+	to get the desired architecture.  This is not a problem for mkpkg or
+	fc, since these utilities automatically generate the -float arguments,
+	but if one calls xc directly the argument must be given.  (9/4)

+
+--------------------
+All tucana architectures and irafx@draco were updated to the latest snapshot

+V2.9.1 and the V2.9 distribution files rebuilt in the network archive.
+(3-9 Sept.)

+	Commented out a couple of lines of code in the code which scans

+math/gsurfit/gsrestore.gx,gsrestorer.x,gsrestored.x
+math/surfit/isreplace.x
+	Changed all the int() calls to nint() calls in the above math
+	package restore routines. This is a totally safe way for the 
+	math routines to do the required floating point to integer
+	conversions and removes any potential precision problems for
+	tasks which read the math package structures back from a text
+	file. This change was made in response to problems encountered
+	with reading text databases on the HP. (LED 9/18)
+
+unix/hlib/zzsetenv.def
+	Removed the default imdir=tmp$ entry.  Having this in zzsetenv.def
+	prevents use of a host level environment definition to set the per-user
+	default, and isn't necessary as IMIO will default to imdir=HDR$ if
+	imdir is not defined.  (10/2)
+
+dataio/doc/wfits.hlp
+	Added some comments to the wfits help page concerning the unwisdom
+	of writing to EOT on a blank tape. Updated the section describing

+pkg/images/tv/doc/display.hlp
+	Modified the description of zrange to note that the minimum and

+	than computed by examination of the full image.  (11/5)
+
+sys/INDEX		+
+	I added a MKTAGS procedure index listing to the SYS directory,
+	to make it easier for people to locate VOS routines without having
+	to know about MKTAGS (since few do, it seems).  This file contains
+	a list of all the procedures defined in all the .x source files in
+	the sys$ directories, giving the calling sequence and source file

+
+sys/qpoe/zzdebug.x
+	1. Modified the `hlist' task to survive the case of a symbol
+	returned by qp_gnfn not being found by qp_gpsym; this can happen
+	when the symbol name is a macro.
+	2. Modified the default debug event list struct to agree with that
+	of PROS/Einstein datafiles, for convenience sake when debugging with
+	this data (the zzdebug code is crude and uses a wired-in compile
+	time event struct).  (11/10)
+
+dev/hosts

+	Added src="script file name" entries to the IMAGES help database

+sys/qpoe/README
+sys/qpoe/mkpkg
+sys/qpoe/qpexgetat.x			+
+sys/qpoe/qpexattrl.gx			+
+	Added the following new routines to QPEX:
+
+	     nc = qpex_getattribute (ex, attribute, outstr, maxch)
+	       nr = qpex_attrl[ird] (ex, attribute, xs, xe, xlen)
+
+	The qpex_getattribute routine is like qpex_getfilter, except that it
+	returns only that portion of the current compiled filter which
+	pertains to the named attribute.  The filter expression for the
+	attribute is returned as a text string.  The family of routines
+	qpex_attrl[ird] are similar, except that they return the filter for
+	the named attribute as a binary range list.  In both cases, the
+	actual filter is stored internally in the QPEX descriptor as a
+	compiled program, hence the attribute or expression is only a
+	representation of the actual filter.  Unless there is a bug they
+	should amount to the same thing, but one should be aware that the
+	internal form of the compiled filter is not a simple range list.
+	(11/12)
+
+sys/qpoe/zzdebug.x
+	Added a new debug task TFILTER, used to verify time filtering.  Also
+	tests qpex_attrld, qpex_getattribute, and the use of QPEX and QPIO
+	independently, using qpex_seti to set the event attribute filter and
+	rewind the event list.  Time filtering is tested by filtering the
+	event list once using the normal optimized time filtering code,
+	saving the x/y of each event which passes the filter in a memory
+	array.  The event list is then rewound, the filter removed,
+	qpex_attrld called to get the time filter as a binary range list,
+	and the raw event list is manually filtered and the x/y of each
+	event which passes the filter saved in memory.  The filter results
+	are then compared to see if they agree.  (11/12)
+
+	[I wasted half a day getting TFILTER working, due to a very uncommon
+	problem.  Changing the name of the task in the task statement in the
+	QPOE zzdebug.x would cause QPEX parsing (totally unrelated) to fail
+	in some cases and work in others.  I traced this to particular file,
+	but when it was recompiled the bug went away.  The newly compiled
+	object, though, was identical to that on orion (V2.9.1).  Short of
+	recalling files from a backup tape, it was impossible to look into
+	this further.]
+
+sys/qpoe/qpexeval.x
+	In testing the time filtering code with the new debug task I found
+	the following bugs.
+
+	1. The code which evaluates the filter expression for a single event
+	was not initializing the value of the expression to false before
+	evaluation.  In most cases this step is redundant (which is probably
+	why I didn't put it in the original code) but it turns out that
+	there is a case in the lookup table code used to evaluate long range
+	lists where the old expression value is pushed before evaluating a
+	subexpression, and an undefined value could be pushed causing events
+	near a range boundary to occasionally be passed when they shouldn't.
+
+	2. The first thing the lookup table code does is map the data value
+	to a bin of the lookup table.  This involves an INT operation, and
+	values a fraction of a data value left of the first bin of the table
+	would have a fractional negative value which INT would convert to
+	a zero, causing values just left of the first bin to erroneously be
+	mapped into the first bin.  (11/14)
+
+unix/os/tape.c
+	Was opening the tape drive with mode 1 when open-write was specified;
+	changed this to open with mode 2, read-write.  (11/15)
+
+sys/qpoe/qpexcode.gx
+	Nested range list evaluation lookup tables occur where a bin of the
+	table at level N maps to so many closely spaced ranges that another
+	lookup table at level N+1 is needed to evaluate the range list for a
+	value that maps into the bin.  Using the new TFILTER debug task to
+	test nested floating time filter lookup tables, I found that a
+	couple of internal variables were not being saved on the stack when
+	the routine recursed to generate code for the new table.  (This is
+	the first time this feature was ever tested, as it has not been
+	needed until now).  (11/15)
+
+sys/qpoe/qpex.h
+	Increased the size of the program and data buffers used for
+	expression evaluation by QPEX.  These can overflow at runtime
+	causing a program abort and the memory is dynamically allocated so
+	we may as well be more generous.  There is still a builtin default
+	upper limit, but if someone does come up with a filter which is
+	large enough to overflow either buffer the size can be increased in
+	QPDEFS before compiling the filter.  (11/15)
+
+pkg/system/doc/help.hlp
+	Added REFERENCES and PHELP to the "SEE ALSO" section.  (11/16)
+
+unix/os/mkpkg.sh
+	Modified the bootstrap code to avoid compiling sources such as
+	getproc.c and tape.c into LIBOS, since these are not part of the
+	library.  The new version compiles all z*.c files plus an explicit
+	list of other files which are part of the kernel, such as
+	irafpath.c, prwait.c, and so on.  (11/19)
+
+pkg/images/doc/gauss.hlp
+	Added a detailed mathematical description of the form of the 
+	Gaussian kernel used in the GAUSS task to the help page. (28/11/90)
+
+pkg/images/filters/t_convolve.x
+	CONVOLVE was not decoding the legal 1D kernel "1.0 2.0 1.0" correctly
+	although the alternate form "1.0 2.0 1.0;" worked. Leading blanks in
+	string kernels as in for example " 1.0 2.0 1.0" also generated
+	an error.  Fixed these bugs and added some  additional error checking
+	code.  (11/28/90 Davis)
+
+dev/hosts [draco, iraf and irafx]
+	Changed path to irafks.e to use "bin.dsux" for cephus.  Other

+	(11/28/90 CB)
+
+unix/boot/spp/xc.c
+	While testing the magtape driver code on Ursa (Sun 470, SunOS 4.1)
+	I had occasion to compile a file and found that XC failed with the
+	message "f77 not found".  The following two changes were made.
+
+	1. There was an actual bug in the code for "run".  This would build
+	the path of the executable, e.g., "/usr/lang/f77", but not use it,
+	calling execv with only the task name, e.g. "f77".  Hence the routine
+	would only work if the executable was found in the user's path.
+
+	2. Evidently the V1.3 compiler cannot even execute unless the
+	directory containing the f77 driver (normally /usr/lang) is in the
+	user's path.  Since we want XC to function properly whether or not
+	the user has /usr/lang in their path, I modified XC to use PUTENV to
+	add /usr/lang to PATH in the environment for the XC process, if f77
+	is found in this directory.  (If f77 is in some nonstandard location
+	then the user will already have the directory in their path).

+	to the null string "". (12/6/90 LED)

+
+sys/imio/impmap.x
+	The "flags" value was being passed to im_pmopen, rather than "mode",
+	causing im_pmopen to get an access mode of zero.  This was harmless
+	when opening masks read only but prevented opening new masks.  (12/14)
+
+sys/imio/immap.x
+	The case of a NEW_COPY .pl image (mask image) was broken out as a
+	special case.  A mask image is created with mode NEW_IMAGE, set to
+	the logical size of the image being copied, and im_make_newcopy is
+	called to copy the header and other inheritable image attributes.
+
+	This is not a normal create-mask operation because the new mask is
+	actually an image stored as a mask which is a new copy of another
+	image; this is not the same as a new mask which is created for use
+	with some reference image.  The main difference is that a mask is
+	always associated with the physical image matrix, and inherits any
+	runtime section defined for the reference image, whereas an image
+	which is a new copy of another image is sized according to any
+	section defined for the old image.  In other words, a new-copy .pl
+	mask-image created from a section of an existing image will be the
+	size of the section being copied, rather than the size of the full
+	image.  Normal mask operations do not work that way, which is why
+	im_pmmap cannot be called directly in this case to make a NEW_COPY
+	mask.  (12/15)
+
+sys/imio/impmmap.x
+sys/imio/impmopen.x
+	The flag PL_BOOL (create boolean mask) was being set in IM_PLFLAGS
+	by im_pmopen, but that was incorrect as this routine doesn't have
+	access to the image descriptor.  Moved the flag setting code to
+	im_pmmap.  (12/15)
+
+sys/imio/impmhdr.x              +
+sys/imio/impmmap.x
+sys/imio/imunmap.x
+	The IMIO image mask support was modified to save the image header in
+	the PLIO save file, and restore the header when the mask is later
+	mapped onto an image descriptor.  The image title string and header
+	cards are stored in the mask "title" string as an arbitrarily long
+	string consisting of a number of lines of text.  In effect, this
+	gives PLIO mask images (.pl images) the same header functionality
+	as, e.g., OIF format images.  Mask images can now be dynamically
+	created, edited, etc., and have full headers, so they can be
+	considered full fledged images except for the one restriction that
+	the pixel type is always integer (with 28 bit unsigned integer
+	pixels).  The semantics of accessing or copying sections, world
+	coordinates, etc., are the same as for any other image format.
+	Randomly accessing an image should be efficient despite the
+	compression, since the mask lines are compressed and indexed
+	individually.
+
+	One possibly useful feature of image masks is that they represent
+	the first machine independent image format for iraf.  Character
+	data is stored as byte packed ascii strings, and the save format
+	for mask image data is an MII short integer sequence.
+
+	Mask images provide a general image compression capability for
+	integer images.  If you try to store a floating image in a mask it
+	will work, but the data will be converted to integer (with
+	incredible compression if the data converts to zeros!).  Since the
+	compression algorithm was designed for masks there will be little
+	compression for noisy 16 bit images.  32 bit integer images, or any
+	smooth (low noise) integer image will compress to some degree.
+	Compression factors for actual image masks, of course, will be very
+	large, with factors of 100-1000 being common.  (12/17)

+	The special case nature of the code to map pixel mask images in

+	was changed so that the user specifed filter would add to or modify

+
+	The expected use of the default filter, which is stored in the

+	Since all the data is nonetheless present, the default filter can
+	be overridden to get at the normally excluded data.  This can be done
+	by editing the value of the deffilt parameter, deleting the parameter,
+	or by overriding elements of the filter in the user specified filter
+	at run time.
+
+	For example,
+
+	    cl> countpoe "foo.qp[time:=@times]"
+
+	would replace the time term of the default filter with the time list
+	from the file "times", preserving any other terms of the default
+	filter, whereas
+
+	    cl> countpoe "foo.qp[time+=@times]"
+	or
+	    cl> countpoe "foo.qp[time=@times]"
+
+	would modify the filter for the time attribute, passing only those
+	events which pass both the default time filter and the time filter
+	given in the file "times".  The new assignment operator ":=" must
+	be used to override any existing filter term; if the usual "=" is
+	used, the default filter term, if any, remains in effect.
+
+	The default filter is a string of the form "attr=expr[,attr=expr...]".
+	This is parsed at qpio_open time just as the user specified filter
+	is, hence the default filter may reference macros, include files,
+	etc.  Operators such as qpex_getattribute and qpex_attrl will return
+	the final filter or range list as used to filter the data, produced
+	by combining the default and user filters.  (12/27)
+
+sys/qpoe/zzdebug.x
+	Added a new debug task SETFILT, used to set the value of the "deffilt"
+	parameter in a QPOE datafile.  (12/27)
+
+sys/qpoe/QPDEFS
+	1. Added a comment at the top to make it more clear that this file
+	is only intended as an example of a QPDEFS file, and to give some
+	pointers regarding how to use the global macro facility.
+	2. Changed the event structure definitions to match those now used
+	in qpoe$zzdebug.x.  (12/28)
+
+sys/qpoe/qpexpand.x
+	This routine copies the input string to the output string, expanding
+	any macros or include file references in the process.  The problem
+	was that qp_gettok returns a string token with the quotes removed,
+	and qp_expand was merely copying tokens out, resulting in the quotes
+	being stripped from string tokens.  qp_expand was modified to
+	restore the quotes to string tokens written to the output stream.
+	I checked various other places where text is pushed back, and all
+	other instances preserved the quotes.  (12/29)
+
+sys/qpoe/qpgettok.x
+	Added support for the builtin symbol or macro "$DFN".  When
+	encountered in the input stream being processed by qp_gettok(), this
+	results in the datafile name being returned as a string token.  This
+	can be used, for example, in macros used to call external tasks,
+	e.g.,  [time=`mytask($DFN,arg,...)`].  (12/29)
+
+sys/qpoe/qpiogetev.x
+	When rereading an event list opened and read earlier, and a PLRIO
+	descriptor was created, any existing PLRIO descriptor would not be
+	closed first.  Added a plr_close call to deal with this case.  (12/29)
+
+sys/qpoe/zzdebug.x
+	Added a new debug task TESTPOE, used to make simple artificial or test
+	qpoe files for testing purposes.  This was used to check out a bug
+	report that events with x=y=1 would pass a filter containing a mask
+	which excluded this corner of the image, however I was unable to
+	duplicate the problem.  (12/30)
+
+sys/qpoe/qpioparse.x
+	This routine was missing a call to qp_closetext(), causing it to leave
+	an open file descriptor behind.  This would cause a task which did
+	many qpio_open() calls to eventually run out of file descriptors.
+	[FDEBUG is very useful to diagnose problems like this).  (12/30)
+
+sys/qpoe/qpioopen.x
+sys/qpoe/qpioclose.x
+	While working on other things I noticed that qpio_open() was not
+	setting the IO_EXCLOSE flag when calling qpex_open to open an
+	expression evaluator.  This did not matter much as qpio_close was
+	not checking the flag to see if it needed to close the QPEX, but in
+	the rare circumstance that a new QPEX was set with qpio_seti() an
+	open descriptor would have been left behind.  Also a QPEX passed in
+	with qpio_seti() woudl be closed by qpio_close() when it shouldn't.
+	Modified qpio_open() to set the flag and qpio_close to check it.

+	Since the default filter (and probably mask eventually) are now much
+	more dangerous or noticeable than previously, I added switches in all
+	the usual places to disable the use of these defaults.  Specifically,
+	in <qpset.h> we have
+
+		QPOE_NODEFFILT
+		QPOE_NODEFMASK
+
+	(default off, i.e., use default filter or mask.  In <qpioset.h> we
+	have the same thing, just at the level of a specific QPIO descriptor:
+
+		QPIO_NODEFFILT
+		QPIO_NODEFMASK
+
+	And for global control by the user we have the new global set options
+
+		set nodeffilt
+		set nodefmask
+
+	which do what they say (omit or comment out these definitions to
+	enable use of the default filter and mask).  (12/31)
+
+sys/qpoe/qpioparse.x
+	As an alternative to the "attr := expr" syntax, which can only
+	override any earlier filter terms for the referenced attribute (such
+	as terms of the default filter) I added some new syntax which can
+	disable the entire default filter and mask for a particular filter
+	expression.  This is done by adding a "!" after the leading "[", and
+	before the new filter, e.g.:
+
+		display "foo[!time=@times.lst,pha=(3,8:11)]"
+
+	would temporarily disable both the default filter and mask.  This
+	does not affect the use of ! within expressions since an expression
+	cannot be the first term of a filter.  (12/31)
+
+sys/qpoe/qpioopen.x
+	A QPOE file is supposed to be able to contain more than one event
+	list, so the default filter/mask facility was modified to permit
+	a different default filter or mask to be specified for each event
+	list.  For example, to define a default filter for event list "foo",
+	one would insert the parameter "deffilt.foo" into the datafile.
+	When looking for the default filter or mask, qpio_open() will look
+	first for the "def[filt|mask].<evl>" parameter, then "def[filt|mask]".
+	(1/1/91)
+
+sys/qpoe/qpiolmask.x
+sys/qpoe/qpioopen.x
+sys/qpoe/qpiosetfil.x
+	The default mask mechanism was modified to provide the same
+	semantics as the default filter.  If a default mask is defined and
+	nodefmask is not set, the default mask is used as a spatial filter
+	for event i/o.  If a default mask is defined, nodefmask is not set,
+	and a user mask is also specified, the user mask is edited using the
+	default mask as a stencil (the new mask is the user mask, with only
+	those pixels set which were also set in the default mask).  Setting
+	nodefmask, QPOE_NODEFMASK, QPIO_NODEFMASK, or using ! or mask:= in a
+	filter expression disables the default mask.  If the mask is set
+	with an explicit qpio_seti() call the default mask is ignored.  (1/1)
+
+sys/plio/plsten.x
+	This routine was evidently not working at all, due to an internal
+	interface change that was never propagated to this routine.  The
+	call to pl_linestencil was missing the maxpixval argument for both
+	the source and destination line lists.  (1/1)
+
+sys/qpoe/qpexcode.gx
+	The QPEX parser syntax for bitmask expressions was generalized
+	somewhat to permit expression negation and parens, e.g., "%1",
+	"!%1", "!(%1)", "!(!%1)", etc. are now handled properly.  Range
+	lists are still not supported for bitmask expressions, as it is
+	not clear that such a feature would be useful (one can just enter
+	a different bitmask instead).  (1/1)
+
+sys/qpoe/README
+	Updated this file to reflect all recent changes to the QPOE

+	Modified the rcardimage help page to include an example of how

+pkg/system/help/help.h
+	The HELP task was modified to add a new parameter "curpack", default

+	to ask the CL the name of the current package; this is necessary to
+	preserve the current semantics of HELP (in the case of task redefs,
+	help for the task in the current package is returned).  The reason
+	for the new parameter is to allow the current package to be
+	specified explicitly to avoid the clcmdw query, e.g., when calling
+	the task at the host level.  (1/4)

+	symmetry in the y direction as well as the x direction
+	resulting in a modest decrease in execution time. Gauss now

+--------------------------
+Tucana system upgraded from SunOS 4.0.3 to 4.1.1.  (2/4)
+Began revisions of Sun/IRAF to support SunOS 4.1.  (2/5)
+
+./*
+	The iraf root was relocated to /u3/iraf on tucana, retaining link
+	at /usr/iraf.  All of the iraf runtime files (sources and bins) are
+	now consolidated on /u3.  (2/6)
+
+unix/*
+	Did a bootstrap of the system (mc68020 version) under 4.1.1 without
+	incident.  (2/6)
+
+local/.login
+local/.exrc
+	Made a number of changes for 4.1.1.  Added OPENWINHOME and MANPATH
+	definitions.  Added /usr/lang (default location of new Fortran
+	compiler) to the default PATH.  FLOAT_OPTION is no longer defined
+	as it is not used by the new compilers and causes a warning message
+	to be issued.  The default IRAFARCH for Sun-3 systems is now f68881
+	if the f68881 binaries are installed.  EXINIT is no longer defined,
+	added a .exrc file instead to allow for vi macros such as the very
+	useful "@".  Deleted the susp/eof control in STTY, it seems time to
+	abandon the DEC defaults and go with the UNIX standard ctrl/z and
+	ctrl/d instead.  (2/6)
+
+unix/boot/spp/xc.c
+	The SunOS version of XC was modified to look for the IRAFARCH
+	environment variable and add a -f68881, -ffpa, etc. switch to the
+	f77 or cc command line.  Specifying any switch beginning with -/f on
+	the XC command line overrides the use of IRAFARCH.  With this change
+	the architecture used for both compilation and linking is controlled
+	entirely by IRAFARCH, and FLOAT_OPTION is no longer used.  So long
+	as IRAFARCH is specified and all modules of a program are compiled
+	with the same setting, mixing of modules or libraries compiled for
+	different architectures is ruled out.  (2/6)
+
+unix/shlib/edsym.c
+	Looking at the edsym code I note that lseek(fd,o,L_SET) is now
+	considered obsolete and one is supposed to use lseek(fd,o,SEEK_SET)
+	instead, including <unistd.h> to define SEEK_SET.  L_SET is still
+	defined for backwards compatibility so I think I will leave things
+	as they are for now.  (No changes.)  (2/6)
+
+unix/shlib/mkshlib.csh
+	1. Modified to support the new Sun V1.3 Fortran compiler.  The iraf
+	shared image is linked explicitly with LD and it is necessary to
+	specify exactly the directories, objects, and libraries to be
+	linked.  These are much different for the new compiler than for the
+	old one.  For example, for f68881 one links with
+	/usr/lang/SC0.0/crt0.o, /usr/lang/SC0.0/f68881/_crt1.o, the libm.a
+	in SC0.0/f68881 (linking with the SC0.0 version of libm.a causes
+	Mlog10[ds] to be unresolved), and the libF77.a in SC0.0.  In
+	principle the directory /usr/lang can be relocated so this is
+	defined as a variable at the top of the file.
+
+	2. The following error message was being reported (by edsym) when
+	linking shared with XC under SunOS 4.1:
+
+	    cannot read shared image version number from <file>.e
+
+	In the code which generates the S.s file (the shared library) I
+	moved ushlib from data space to text space.  Evidently under 4.1.1
+	the system is more clever and can have initialized data at addresses
+	for which corresponding file offsets do not exist in the executable
+	file.  This results in a seek to an offset beyond the end of the .e
+	file, leading to the error message shown above.  Since ushlib is not
+	modified at runtime we can just as easily have it in text space,
+	which avoids the problem.  A simple workaround for this problem is
+	to link -e (no edsym symbol table editing).  (2/6)
+
+unix/hlib/mkpkg.inc
+	Added -libmil (use inline templates) and -dalign (double align type
+	double data) to the list of default mkpkg compile switches for the
+	new compiler.  By default the compiler will use optimization level -O3
+	and on a Sun-4, will compile -cg87.  This latter option is necessary
+	for code compiled for a Sun-4 to run on both older and newer Suns,
+	which have different floating point units.  There is another option
+	-cg89 which tells the compile to take advantage of certain features
+	of the newer floating point units (e.g. hardware sqrt) but we can't
+	use that for binaries that must run on all sparc systems.  (2/6)
+
+unix/hlib/mkpkg.sf.SUN3
+unix/hlib/mkpkg.sf.SUN4
+	Commented out all the bug entries, we should start over with this
+	new compiler.  (2/6)
+
+---------------------
+Started full f68881 sysgen/recompile.  (2/6)
+
+unix/hlib/mkpkg.sf.SUN3
+	The files vops$ak/{abnekx.x,abnex.x} and vops$lz/aveqx.x, all of
+	which contain equality comparisons of complex numbers, produced the
+	following message from the V1.3 compiler:
+
+	    warning: unexpected parent of complex expression subtree
+
+	Compiling the files without optimization avoids the problem.  The
+	floating point or complex equalities used in these routines are
+	questionable, but there does not appear to be anything wrong with
+	the code.  (2/7)
+
+unix/boot/spp/xpp/decl.c
+	The d_runtime() routine returns in a char argument any runtime
+	initialization text needed for a procedure.  The routine would do
+	nothing if no initialization was required, which was incorrect, as
+	any old text in the string buffer argument would then be reused.
+	Modified to write an EOS into the output string in this case.
+	This bug was introduced as a result of a recent change in V2.10
+	iraf.  (2/7)
+
+pkg/cl/compile.c
+	The CL failed to come up after the sysgen.  This was eventually
+	traced to the compile() function.  This contains a register flag
+	"status" which was used without being initialized.  The routine
+	would operate correctly provided the (random) value of the variable
+	was anything other than ERR.  This is highly likely which is why
+	the bug has gone undetected for so long.  (2/7)
+
+unix/sun/Makefile
+	Changed the suggested values of FLOAT from fswitch/fsingle for
+	Sun-3/other to -f68881/"".  (2/7)
+
+-----------------------------------

+Sparc bootstrap completed; sparc sysgen begun.
+Sysgen of f68881 binaries for noao packages begun.  (2/7)
+
+unix/hlib/mkpkg/host.c
+	In the sparc sysgen I got an error message complaining that a $purge
+	directive had failed.  It turns out that the unix/iraf version of
+	h_purge in host.c is a no-op and does not even return an exit status,
+	which is incorrect as the status of the routine is checked by the
+	portable mkpkg code.  I modified it to always return an exit status
+	of OK.  Checking the rest of the routines in the file, there was
+	one other routine which inconsistently returned status values and I
+	fixed that as well.  (2/8)
+
+unix/hlib/mkpkg.inc
+	Deleted the "-dalign" switch from all X*FLAGS entries.  It turns out
+	that the CL does not begin to double align double data, and cannot
+	be easily modified to do so, so this cannot be used, at least with
+	the CL C code (SPP pretty much double aligns all double data so there
+	is no problem there).  This option only affects Sun-4s, i.e., the
+	already compiled f68881 code is not affected by this switch.  (2/8)
+
+-----------------------------------
+ffpa sysgen begun.  (2/8)
+
+unix/boot/spp/xc.c
+	The ffpa sysgen went fine except that all the links failed with a
+	ffpa_used unresolved external message.  This was occurring due to
+	the -Bstatic and the reference was occuring in one of the C libraries.
+	It was necessary to add a -f<float-option> switch to the CC command
+	used for the link to avoid the problem.  XC explicitly links all the
+	right Fortran libraries for a given architecture, but it is still
+	necessary to pass the -fxxx flag for the benefit of the C libraries.
+	(2/8)
+
+bin.ffpa/S.e
+bin.f68881/S.e
+bin.sparc/S.e
+unix/boot/spp/xc.c
+	Since shared image version support has been around for a year or so
+	and V2.10 no longer uses the older shared images I deleted S.e and
+	S4.e in the recent sysgens, leaving only the current (actually V2.9)
+	shared image S5.e.  It turns out however, that XC needs to have a
+	file entry S.e in the directory containing the real shared image in
+	order to permit runtime searching to find the file (runtime searching
+	is necessary to provide architecture support, IRAFULIB support, etc.).
+	XC could search for S<n>.e except that it is difficult to determine
+	the shared image version number.  The simple solution was to add a
+	file entry S.e in each of the core system BIN directories.  This is
+	not an actual shared image, rather a zero length directory entry used
+	to flag the directory containing the real shared image or images.
+	If this marker file is not present the system will still run, but
+	link time EDSYM symbol editing will be disabled.  (2/10)
+
+unix/shlib/mkshlib.csh
+unix/os/zmain.c
+unix/os/zzstrt.c
+unix/os/zshlib.c
+	It turned out that zmain/zzstrt were using the ushlib vector to pass
+	the sh_debug flag, used to map the shared image text writable so
+	that debug breakpoints can be set (as in :r -w in adb).  This was a
+	bit of a trick and doesn't work any more since I moved ushlib to the
+	text segment, so I made sh_debug an explicit variable in data space.
+	It is defined in the shared library (libshare.a) or in zshlib.o if
+	linking unshared.  (2/10)
+
+unix/hlib/install
+	I added a rm -f preceeding each ln -s, since ln will not clobber
+	any existing link.  This could occur in certain cases when link
+	/usr/include/iraf.h already existed but had the wrong value.  (2/10)
+
+unix/as.sparc/oscmd.s		+
+unix/hlib/mkpkg.sf.SUN4
+	After the sparc sysgen with the new compiler all OS escapes would
+	fail with the error "cannot open `A'".  This was traced to a host
+	compiler error for file oscmd.x.  The null string "" was being passed
+	to a subroutine; in Fortran this is a short array of length 1
+	initialized to zero, but the compiler was initializing the value to
+	random garbage, in this case A (in tests I ran other values were
+	generated).  Other identical cases of "" being passed to subroutines
+	in the same file were compiled correctly.  Compiling without
+	optimization did not help, so I had to edit the assembler and place
+	the file on the special file list.  (2/10)
+
+---------------------------------
+SunOS 4.1.1 / Sun Fortran 1.3.1 upgrades completed (except for full
+testing and further bug fixing).  (2/10)
+
+iraf/dev/devices  [Ursa only]
+        Added mti to the devices file for libra's 9track tape drive.  It
+        was interesting that there was no entry in the devices file when
+        libra was served by orion - but then the host names were the same
+        for both orion and libra's mtas.
+
+sys/qpoe/qpioparse.x
+	The event list filter syntax supports runtime specification of the
+	event coordinate system to be used with the notation key=(xoff,yoff)
+	where xoff,yoff are event field specifiers, e.g., (s0,s2).  Fixed
+	two problems with the code in this routine which parses the KEY
+	keyword: 1) whitespace etc. was not being skipped properly, causing
+	the key= expression to be rejected, and 2) the offset values were
+	being used directly, which is incorrect, since at the user level
+	event struct offsets are specified in bytes, whereas in the QPIO
+	descriptor short integer offsets are used for efficiency reasons.
+	With these problems fixed the key=(x,y) feature checks out, i.e.,
+	QPIO itself handles the key properly and it was only the parsing
+	routine which had problems.  (2/10)
+
+dev/devices 	[tucana]
+	deleted mt device aliases no longer used in OS 4.1.1  (2/12 ShJ)
+
+sys/qpoe/qprenamef.x
+	This routine renames a header parameter by creating a new one and
+	setting the deleted bit in the old one.  There was a subtle bug
+	which could cause the old parameter to fail to be deleted.  The
+	routine was indeed setting the delete bit in the symstruct of the
+	old parameter, but it was doing so *after* adding the new parameter
+	to the SYMTAB symbol table.  This was not correct because the
+	symstruct of the first parameter was being referenced by an absolute
+	pointer the value of which was computed before the new parameter
+	was added.  In SYMTAB adding a new parameter can cause the symbol
+	table to be reallocated, invalidated any such pointer.  (2/13)
+
+sys/qpoe/qpgnfn.x
+	1. The pattern string input by the user was being used almost directly,
+	after only * -> ?* mapping.  Any match was accepted.  This is
+	incorrect because we want to accept matches which only match the
+	*entire* field name.  It is necessary to constrain the match to
+	begin at the beginning of the string being checked, and verify that
+	the entire string is matched.
+	2. Sorting was not working correctly.  The package was using zero
+	indexed string buffer offsets internally, and calling STRSRT with
+	this index array.  This is incorrect because STRSRT expects a one
+	indexed index array.  The result was that the list would be sorted
+	ignoring the first character of each string.  (2/13)
+
+sys/qpoe/zzdebug.x
+	Added a "sort" parameter to the HLIST task.  (2/13)
+
+sys/imio/db/imgnfn.x
+sys/imfort/db/imgnfn.x
+pkg/images/doc/hedit.hlp
+	Since the QPOE gnfn code was derived from IMIO I figured the IMIO
+	code might have the same bug and indeed it did (the pattern matching
+	bug, not the sort bug).  Fixing this should fix the problem of HSELECT
+	matching field names using a prefix-match rather than full match.
+	The IMIO version was mapping * to ?* and was constraining the match
+	to the beginning of the name, but was not checking for a full
+	length match.  This was not completely trivial as the name being
+	matched is embedded in a FITS card, hence space or "=" terminates
+	the name, rather than EOS.  (2/13)
+
+sys/ki/ki.h
+sys/ki/kighost.x

+unix/hlib/mkpkg.sf.SUN4
+	Evidently with the latest OS, the sparc register set is no longer
+	saved with the version of SETJMP found on a Sun-4.  This would cause
+	a process executed on a Sun-4 to die in the iraf main during error
+	recovery, upon return from the ZSVJMP call.  Compiling without
+	optimization so that the compiler does not cache values in registers
+	seems to avoid the problem.  I added etc$main.x to the special file
+	list to be compiled without optimization, although this is probably
+	going to be sufficiently common problem that we might want to
+	consider some more machine independent way of always compiling
+	without optimization routines that use ZSVJMP.  (2/14)

+	the rejection limits were not being computed correctly. In the

+pkg/images/tv/display/sigl2.x
+	The routine si_blkavgs, which is used to block average an image

+	These tasks have supported multiple -p pkg arguments for some time,

+	one mkpkg.inc in addition to the global core system one).  The PKGENV
+	environment variable was generalized; this can be now be a

+	1. Added a full CLIO interface definition to the README file.
+
+	2. The pset routines cl[gp]pset, used to get/put the values of
+	string valued parameters, where named to cl[gp]pseta as the old
+	names were too misleading (what does it mean to get/put a pset).
+	The old routines are retained for compatibility but are now
+	considered obsolete.
+
+	3. The CLGFIL routines are also now considered obsolete.  clgstr
+	and fntgfn etc. should be used instead.  It doesn't make any sense
+	to have a system routine that arbitrarily combines two such 
+	different facilities as get-string and the file name template
+	package (if this is justified then any number of other equally
+	logical combinations are possible too).
+
+	4. Added a new routine CLEPSET to the pset package.  This is called
+	to "edit" a pset.  So far as the application is concerned all this
+	means is that the pset values can be changed by the operation.  In
+	the specific case of the current combination of CLIO and the CL,
+	EPARAM is called to edit the pset and the edited values are updated
+	in the parameter cache in the local process.  This routine is still
+	considered experimental.  (6/22)
+
+pkg/cl/task.h
+pkg/cl/exec.c
+pkg/cl/opcodes.c
+	Minor changes to the CL were required to support the CLEPSET
+	routine.  clepset uses dparam to efficiently obtain the edited pset
+	and update the local parameter cache.  A way was needed to redirect
+	the output of a task like dparam back to CLIO in a subprocess.  A
+	hidden special file ("IPC$IPCIO-OUT" currently, but this could
+	change at any time) was defined such that if a task is run with the
+	output redirected as in "dparam > IPC$IPCIO-OUT" the stdout of the
+	task is sent to t_out, the CLIN of the subprocess which issued the
+	command.  When the task terminates the message "# IPC$IPCIO-FINISHED\n"
+	is sent to mark the end of the output from the task.
+
+	These changes are considered internal to CLIO.  The method used to
+	implement this feature is a minimum-modification approach which
+	only solves a part of a more general problem, hence this facility
+	should not be used outside of CLIO.  (6/22)

+sys/etc/main.x
+	1. Added a new routine clc_compress() to the CLIO parameter cache
+	code, with a call to this routine in clepset().  The caching
+	mechanism handles parameter updates by simply redefining the
+	parameter and its value in the symbol table; if there are many
+	parameter updates significant wasted space can result.  clc_compress
+	rebuilds the cache symbol table, saving only the most recent entry
+	for each parameter.
+
+	2. Modified clc_init() to permit it to be called repeatedly to
+	reinitialize the parameter cache.  Modified main.x to use clc_init
+	instead of clc_mark/clc_free to reinitialize the cache before
+	running a task.  This was done to eliminate the external marker,
+	which would be invalidated after rebuilding the cache symbol table
+	in an operation such as clc_compress.  (6/23)

+sys/gio/imdkern/idk.x
+	The arguments "frame" and "color" to the idk_open procedure were

+	or of the full parameter cache, to an output file using a caller

+	It was necessary to change the name of the recently added procedure

+	qsort procedure is defined in hlib$iraf.h as "xqsort".  The best
+	thing to do would have been to change this definition to something
+	more obscure, but this would have required recompiling all existing
+	applications that use qsort, and worse, since there would be a new
+	procedure xqsort with a different calling sequence, existing 
+	applications using the new shared image would get the new xqsort
+	and would have died with a segvio when the program was executed.
+	It is easier to pick a new name then force recompilation of the
+	existing applications.  (6/27)

+	1.  The image keyword list (gnfn) stuff, which was modified earlier
+	to require full keyword matches for header keywords, would still
+	permit partial matches for the standard builtin keywords (there
+	was a second call to patmatch, used to check the stadard keywords,
+	which was missed earlier).
+	2. Tightened up the keyword matching performed on the naxisN keywords.
+	Formerly there would have been a conflict if a user keyword happened
+	to have a name such as "naxisNfoo".
+	3. In imgftype, there was some code in the procedure to check for

+	1. Added a new routine hd_debug to helpdir.x.  This dumps the

+	debugging purposes (it is not used in the runtime system).
+
+	2. The routine hdb_make_rhd, used to make the root help directory
+	(directory of packages), contained a line HD_NMODULES(hd) =
+	HDB_NENTRIES(db) which was incorrect; this could add extra,
+	unitialized modules to the help directory just assembled, possibly
+	leading to a segementation violation when later the unitialized
+	entries were referenced.  This was causing segmentation violations
+	when many external packages were loaded (the bug would only come
+	into effect with root help directories, and each external package
+	has one).  The bug has always been there, it is just more likely to
+	cause a problem when there are many packages.  (7/10)

+	cases but should make it easier for people to customize things if
+	they want, without requiring a loginuser.cl.
+	2. If the file ".hushiraf" is seen during login the message of the
+	day is not printed and cl.menus is set to no.  This makes it
+	possible to get a simple cl prompt without all the other verbiage
+	being printed, which experienced users don't necessarily want
+	to see during every login.
+	3. Deleted some old stuff that has been commented out for quite a

+	The qpex_attrl routine would fail for attribute expressions

+	MIO_SETRANGE still wasn't working correctly so I had a more careful
+	look at the mio_[gp]l routines.
+
+	1. The fix made earlier to initialize the "ve" vector was incorrect,
+	as any data that wants to be saved between calls has to be saved in
+	the i/o descriptor and "ve" is a local variable.  Moved the "ve"
+	initialization to immediately before the call to imggsc, where the
+	variable is used.
+
+	2. Made extensive changes to the way the "V" vector is handled.
+	This is passed back by the routines in each call to give the
+	coordinates of the first pixel of the referenced line segment.
+	Modified the routine to pass back a vector matching the image
+	dimension rather than of length IM_MAXDIM, to lessen the chance
+	of overrunning the client's buffer.  Fixed a bug that was preventing
+	the routine from returning correct vector coordinates when doing
+	i/o on a subregion (mio_setrange) of the image.  Fixed a bug that
+	would cause the data pointer to be offset when accessing subregions.
+
+	3. By default the coordinates of the V vector returned by the
+	mio_[gp]l routines will be relative to any subregion specified
+	with a prior call to mio_setrange.  This is convenient when using
+	mio_setrange to randomly access subregions of the image.  If this
+	is not what is desired it is now possible to follow the mio_setrange
+	call with a call to "mio_seti(mio,P_REGCOORDS,NO)" to cause the
+	V vector to be returned in image rather than region relative
+	coordinates.  This is more convenient for applications that use
+	mio_setrange only to optimize i/o and want this to be transparent
+	to the rest of the code.  (7/28)
+
+pkg/images/geometry/t_imshift.x
+        The shifts file pointer was not being correctly initialized to NULL 
+        in the case where no shifts file was declared. When the task
+	was invoked repeatedly from a script, this  could result in an array
+	being referenced,  for which space not been previously allocated.

+
+unix/hlib/extern.pkg	URSA ONLY
+	Changed ccdacq from /u2/rooke/ice/ccdacq/ to

+	versions on ursa.  (7/31/91 SRo)

+	Added the copyright notice from the BSD source.  Berkeley finally
+	made this source publically available without a unix source license,

+
+sys/imio/iki/stf/stfaddpar.x
+	Added a case for TY_BOOL (LOGICAL*4), and changed the abbreviated

+
+sys/mwcs/mwgsys.x		+

+unix/sun/imtoolrc
+unix/sun/imtool.c
+	Added several new entries to the imtoolrc file.  Increased the

+
+pkg/cl/exec.c
+	There was a bug in the oneof() function in how the "alldone" flag
+	is set to cause termination of a background process.  The flag
+	would be set when attempting to pop (at task termination) a task
+	that has the T_BATCH flag set.  The problem is that this test
+	would result in the continued execution of the task *after* execution
+	of the background command completed.  In the normal case of a
+	background command submitted interactively on the command line this
+	would be harmless as the task would be "cl", which would see EOF
+	on the stdin and exit.  In more complex cases, e.g., an executable
+	task or a script reading from a file, this could result in an
+	attempt to read from a stream that existed in the foreground CL
+	but which was never opened in the background CL.
+
+	The particular case in which this showed up was in the OBSERVE task
+	in CCDACQ, when submitting the command "display <image> 1 &" to
+	the CL from the subprocess, using clcmd.  The display task would
+	run normally, being left behind in the process cache as the first
+	non-system process.  The task descriptor for the observe task in
+	the background cl would be set up to read from a connected subprocess,
+	and after execution of the display command would resume waiting for
+	commands from the subprocess.  Meanwhile, the subprocess actually
+	in the cache would be display rather than observe, and display would
+	have already terminated, resulting in deadlock with both the CL
+	(observe) and the display task executable waiting for a command.
+	Due to the deadlock the background job would never terminate and
+	after this sequence had repeated several times background job
+	submission would fail in the foreground cl with "no more background
+	job slots".  (8/18)

+	Added the six new ICE imtool frame buffer entries.  (8/27/91 SRo)
+
+sys/qpoe/qpexmodfil.x
+	There was a simple bug in the buffer reallocation code which would
+	cause filter expansion to fail for expressions longer than 1024
+	characters.  A "sz_expr = INC_SZEXPRBUF" should have been
+	"sz_expr = sz_expr + INC_SZEXPRBUF".  (9/04)
+
+unix/shlib/mkshlib.csh		[not modified]
+	After a sysgen all sparc executables would fail to run due to an
+	access violation.  This was due to a problem with the shared image;
+	the data and text segments were overlapping by 8 bytes, evidently
+	due to a linker bug in SunOS 4.1.1.  I worked around the problem by
+	manually relinking the shared image including a dummy object "foo.o"
+	in the link to make the text segment slightly larger.  Since the
+	text size of the shared image will change as soon as any code is
+	changed, it doesn't seem worthwhile to devise a more permanent
+	workaround.  It looks like the linker fails to align the data segment
+	properly if etext is close to a page boundary.  (9/07)
+
+unix/hlib/math.h
+	Changed the name of the define "E" to "BASE_E", to decrease the

+	It was possible for integer overflow to occur for case linear in the

+	(9/20)
+
+pkg/system/help/helpdb.x
+	There were still problems with the code in helpdb which reorders
+	the package index help directory to depth-first order.  A bug
+	which would cause commands such as "help lists.*" to print each
+	module twice was traced to this code.  The help directory
+	reordering code was rewritten (inverting the two main loops) to
+	ensure that the reordered help directory does not have any holes
+	in it, and that the number of modules is correct.  (9/21)
+

+	Changed aliases in dev$hosts on tucana, orion, gemini, ursa,
+	and draco for downtown node "morrison" to "vegemite".  (CB, 9/21/91)
+
+-----------------------------------------------------------------------
+Merge changes (including many minor bug fixes) from A/UX IRAF port.
+This includes support for GCC and ANSI C, and limited SYSV support.  (9/21)
+
+unix/hlib/install
+	1. Added a #!/bin/csh at the top of the script.
+	2. Added a "set path" so that explicit paths to executables can be
+	avoided.  Changed "/etc/chown" to "chown" (this utility is in
+	different places on different systems).
+	3. I had trouble on A/UX with the $hbin/sgi2* $hlib/sgi2* stuff in
+	MODEFILES.  The second did not expand to anything and the string
+	"$hlib/sgi2*" was left in MODEFILES with the * unexpanded, causing
+	problems later when appended to a directory prefix.  Since there are
+	not supposed to be any executables in hlib anyhow I deleted the
+	second reference.
+	4. In the code which checks the MODEFILES, I added a test to see if
+	$file exists as named, before looking for it in each of the
+	directories.  Otherwise the $hbin/sgi2* entries, which are already
+	fully resolved pathnames, expand to pathnames referencing
+	nonexistent directories when a BINDIRS prefix is prepended.
+	This could cause the install script to bomb on A/UX.
+	5. Changed all occurrences of constructs like `ls ...` to `$LS ...`
+	with LS defined as /bin/ls at the top of the file.  The problem is
+	that a subshell is spawned to evaluate the command in the back
+	ticks, and if "ls" is defined as an alias in a .cshrc file, as is
+	typically necessary on SYSV systems (to get -C) the alias will be
+	used, causing the output to be different than expected by the script.
+	(9/21)
+
+unix/hlib/irafuser.csh
+	Generalized somewhat - added some commented out GCC definitions,
+	and new definitions for CC, F77, HSI_F77LIBS, and RANLIB.  These
+	are used in the mkpkg.sh files (used to bootstrap the HSI).  (9/22)
+
+unix/hlib/mkfloat.csh
+	Added a definition TARXFLGS, with BSD and SYSV versions.  (9/22)

+	to "$F77".  Changed all occurrences of "ranlib" to $RANLIB.  (9/22)
+
+unix/setarch.sh
+        The A/UX version of "test" does not have the -h flag to test for
+        symbolic links, so the existing script did not work.  Still trying
+        to find a portable way to do this, I changed the script to use the
+        construct:  if [ "`ls -d as`" = "as" ]; then ...  (9/22)
+
+unix/os/alloc.c
+        1. The file header comment section contained the sequence "for the
+        /dev/* entries...".  The "/*" would cause a warning from gcc that
+        there might be a comment buried in another comment, which can cause
+        a comment to terminate prematurely.  In this case it was harmless
+        and indeed there was no error, but I changed the text to eliminate
+        the warning.
+        2. Moved the #include <sys/types.h> to before the #include <utmp.h>,
+        as the A/UX version of the latter requires the former, and SunOS
+	doesn't care.  (9/22)
+
+unix/os/prwait.c
+        In pr_getipc(), deleted unused variables error_code, error_status,
+        waitpid.  (9/22)
+
+unix/os/zalloc.c
+        1. In ZDVALL, deleted unused variable x_status.
+        2. Deleted unused variable i in loggedin().  (9/22)
+
+unix/os/zfioks.c
+unix/hlib/irafuser.csh
+        1. Deleted the old, commented out code for rcmd(), as variables
+        defined for this were being reported as unused.  Added a comment
+        explaining that rcmd and friendly-host authentication cannot be
+        used without making the process suid root.
+        2. Added #ifdef SYSV support for SYSV termio.  Terminal driver ioctls
+	are used in this routine to set raw mode for the password prompts.
+        3. GCC was complaining that the setjmp/longjmp used in zardks,
+        zawrks could cause certain register variables to become undefined
+        (op and nbytes in zardks, ofd in zawrks), so I changed the storage
+        class from register to auto for these variables.
+	4. GCC would still warn that longjmp could clobber the values of
+	several local variables in zardks.  Evidently this is a feature of
+	ANSI C.  The values of automatic variables not declared "volatile"
+	are not guaranteed to be preserved in a longjmp.  Added a -DANSI to
+	irafuser.csh and some #ifdef ANSI code to zfioks.c to provide the
+	necessary (but not non-ANSI backwards compatible) definitions. (9/22)
+
+unix/os/zfiolp.c
+        I had to change the declaration
+
+            static PKCHAR xnullstr[1] = XEOS;
+        to
+            static PKCHAR xnullstr[1] = { XEOS };
+
+        (PKCHAR=short and XEOS=0) or GCC would complain about an invalid
+        initializer.  Must be a feature of the ANSI C syntax.  (9/22)
+
+unix/os/zfiotx.c
+unix/hlib/libc/kernel.h
+        1. Modified to add #ifdef SYSV support for SysV terminal i/o.
+        2. GCC complained about some functions which were used (default
+        storage class extern) and later declared static; added static
+        declarations for these functions to the file header to eliminate
+        these (harmless) warning messages.
+        3. Another longjmp warning, this time in zgettx.  Variable "op" might
+        not be saved over a longjmp.  In this case I was able to avoid the
+        problem merely by moving the op initialization statement to after
+        the setjmp.  (9/22)
+
+unix/os/zfxdir.c
+        Deleted unused local variable "ch".  (9/22)
+
+unix/os/zgcmdl.c
+        Deleted unused local variable "ev".  (9/22)
+
+unix/os/zgtime.c
+        Had to #ifndef SYSV the #include <sys/timeb.h> as this file does
+        not exist on SysV systems.  (9/22)
+
+unix/os/zmain.c
+        Deleted unused local variables "junk" and "wsetsize".  (9/22)
+
+unix/os/zwmsec.c
+        Added "static" to explicitly specify the storage class in the first
+        declarations of "napmsx", which is declared static in the source
+        given later in the file.  (9/22)
+
+unix/os/zxwhen.c
+        1. GCC did not realize that the call to kernel_panic in zxwhen was
+        an exit, and would warn that the value of variable "vex", used later
+        in the procedure, could be unitialized.  Added a statement to init
+        this to null to avoid the warning message.
+        2. In zxgmes, the char pointer to the returned error message was
+        not being initialized if no error had occurred.  Modified to return
+        the null string in this case.  (9/22)
+
+unix/os/zzstrt.c
+        Added #ifdef SUNOS4 conditionals around certain declarations which
+        are used only the #ifdef SUNOS4 code which follows, to avoid unused
+        variable warnings on non-Sun systems.  (9/22)
+
+unix/boot/bootlib/envinit.c
+        Deleted the unused variable "osfn" in loadpkgenv.  (9/22)
+
+unix/boot/bootlib/bootlib.h
+        Deleted the commented out #define NOVOS definition, which causes
+        a /* in comment warning and doesn't need to be in this file anyhow.
+        (9/22)
+
+unix/boot/bootlib/osfcopy.c
+        1. Deleted the unused variable "binary_file".
+        2. Added a return at the end of the function, to guarantee that
+        a function value was returned.  (9/22)
+
+unix/boot/bootlib/ostime.c
+        Modified with #ifdef SYSV for SysV.  This whole business needs to
+        be redone sometime to provide rigorously correct time primitives
+        for iraf.  (9/22)
+
+unix/boot/bootlib/vfn2osfn.c
+        Local variable "first_time" defined but never used.  (9/22)
+
+unix/boot/generic/generic.c
+        1. In copy_comment(), added an entry time initializer for the
+        local variable "flag".
+        2. GCC complained about the variable "ch" in evaluate_expr() possibly
+        being used before being initialized.  This looked harmless in this
+        case, but I added a global initializer to eliminate the warning
+        message.  (9/22)
+
+unix/boot/mkpkg/host.c
+        1. Deleted a couple of unused "exit_status" variables.  Changed some
+	"return(exit_status=N)" constructs to separate assignment and return
+	statements in cases where the function does not return a value.
+        2. Deleted unused variable "ip" in search_mkpkgfile().
+        3. Added a #ifdef SYSV to the code which calls RANLIB, since this is
+        not used on SYSV (COFF) systems.  (9/22)
+
+unix/boot/mkpkg/mkpkg
+unix/boot/mkpkg/mkpkg.h
+unix/boot/mkpkg/scanlib.c
+        1. Added a #include "mkpkg.h" to scanlib.c.  This file includes extern.h
+        which references a structure defined in mkpkg.h.
+        2. Deleted unused local variable "key" in h_scanlibrary().
+        3. Replaced the MAX_SYMBOLS definition in scanlib.c by MAX_LIBFILES,
+        as there is also a MAX_SYMBOLS in mkpkg.h which means something
+        quite different.  (9/22)
+
+unix/boot/mkpkg/sflist.c
+        In sf_scanlist, the GCC static analysis indicated that variable "tail"
+        could possibly be used without being initialized.  Added code to
+        initialize tail=head before scanning the list.  (9/22)
+
+unix/boot/mkpkg/tok.c
+        1. In do_if(), in the event of a syntax error the local variable "bval"
+        could be used without being initialized.  Once again probably harmless
+        but it makes GCC complain.
+        2. Unused variable "ch" in do_call().
+        3. Module do_include() was not returning an exit status in all
+        cases.  (9/22)
+
+unix/boot/rmfiles.c
+        1. Unused variable "i" in main().
+        2. Another warning from GCC static analysis suggesting that local
+        variable "fp" might be being used before being initialized (definitely
+        not in this case, but I added an initializer to avoid the message).
+        (9/22)
+
+unix/boot/wtar/wtar.c
+        Unused variable "op" in putheader().  (9/22)
+
+unix/boot/spp/xc.c
+        1. Unused variable "cmdbuf" in main().
+        2. Variable "append" in sys() could be used before being
+        initialized.  (9/22)
+
+unix/boot/spp/xpp/xppcode.c
+        1. Unused variable "irafdefs" in do_include().
+        2. parse_task_statement() did not return a function value in all cases.
+        3. accum() did not return a function value in all cases.
+        4. Unused variable "digit" in charcon().  Function did not return
+        a value in all cases.
+        5. Variable "value" not initialized in all cases (when an error
+        occurs, but it causes a warning message).  (9/22)
+
+unix/boot/spp/xpp/decl.c
+        1. Local variable "sp" was not being initialized in all cases (i.e.,
+        when an error occurred).
+	2. Added a new procedure d_declfunc which is called to output function
+	declarations.  Currently this doesn't do anything special, but it
+	provides a single point of modification should it be necessary to do
+	any special processing of function declarations in the future (for
+	example intrinsic functions).  (9/22)
+
+unix/boot/spp/rpp/ratlibc/getlin.c
+        The local variable "c" was not being initialized in all cases.  (9/22)
+
+unix/gdev/sgidev/sgidispatch.c
+        Deleted unused local variables "maxch" and "status".  (9/22)
+
+unix/os/gmttolst.c
+        Added #ifdef SYSV support.  SYSV uses a global variable "timezone"
+	(a questionable construct - see below) while BSD uses a time_info
+	structure returned in a function call.  (9/23)
+
+unix/os/zzstrt.c
+	This problem was indirect and hence difficult to track down.  The
+	time-task feature of iraf, e.g., "$imstat dev$pix", when run for the
+	first time in a new process, would return a clock time such as
+	"-416:+0" instead of "0:13" or whatever.  Thereafter it would be ok,
+	until the process was restarted.  This turned out to be due to the
+	clock time returned by the first call to ZGTIME being wrong.  The
+	eventual solution was to add a call to TZSET to zzstrt to initialize
+	the SysV time stuff before any time calculations take place.  What I
+	suspect was happening is that in gmt_to_lst I was accessing
+	"timezone", which is a global data variable in SysV, but the value
+	was being changed sometime later in an indirect call to TZSET.
+	Using a global variable for something like this that is evidently
+	not constant is a very questionable feature of SVID (unless this
+	was a bug in A/UX).  (9/23)
+
+unix/os/mkpkg.sh
+        Changed the "rm alloc.o" to "rm -f alloc.o", as the .o file is
+        not being left behind on this system, using GCC.  (9/23)
+
+unix/os/zfiopl.c
+        In zclspl, another case of an array aggregate initializer "= val;"
+        having to be changed to "= { val };" when initializing an array of
+        length 1.  (9/23)
+
+unix/os/zoscmd.c
+        1. Modified so that if SYSV is defined, "fork" is used instead of
+        the BSD-ism "vfork".
+	2. On Sun systems <vfork.h> is included (disables the global optimizer
+	on sparc systems due to nonstandard register usage).  (9/23)
+
+unix/boot/spp/rpp/ratlibr/defs
+	Replaced by the version rpprat/defs (they should be the same, although
+	in this case the differences did not affect the ratlib code).  (9/24)
+
+unix/boot/spp/rpp/ratlibr/Makefile
+unix/boot/spp/rpp/rpprat/Makefile
+	These makefiles now use a .r.f rule using /usr/local/bin/ratfor to
+	generate the .f files, rather than using f77 -F, which requires
+	replacing the host version of ratfor.  (9/24)
+
+unix/boot/spp/rpp/ratlibf/*.f
+unix/boot/spp/rpp/rppfor/*.f
+	Regenerated all the preprocessor Fortran sources.  The new files are
+	lower case.  Although upper case source is standard Fortran, all
+	modern compilers I am aware of accept lower case source (SPP outputs
+	lower case after all), and a case sensitive compiler may generate
+	upper case externals for upper case procedure names, causing a case
+	mismatch when linking with the C support library.  (9/24)
+
+unix/boot/spp/rpp/ratlibc/r4tocstr.c
+	Installed a minor bug fix which allows the routine to accept as
+	input character arrays consisting of either one char per integer, or
+	a char plus 3 blanks per integer.  The old F66 convention of
+	assigning one Hollerith character to a binary integer can generate
+	either type of integer value.  (9/24)
+
+sys/imfort/imemsg.x
+        This file contained four Fortran escapes (error message strings)
+        which ran over the 72 character line limit of Fortran.  (9/24)
+
+sys/gio/nspp/portlib/gridal.f
+        The equivalence on line 4 was incorrect (or at least ill-advised)
+        due to a dimension error.  The code "mfmtx(1),ifmt(1))" should
+        have been "mfmtx(1),ifmt(1,1))".  (9/24)
+
+sys/gio/nspp/portlib/z8zpbd.f
+sys/gio/nspp/portlib/z8zpii.f
+	The z8zpbd.f file was using DATA statements to initialize variables
+	in common (works on most systems but is technically illegal).  I
+	moved all the remaining DATA statements out of z8zpbd.f into run
+	time initialization statements in z8zpbd.f  (9/24)
+
+unix/boot/spp/xc.c
+        The routine printargs() was attempting to print one more argument
+	than it should, due to a <= that should have been a < in a FOR loop.
+	(9/24)
+
+pkg/system/help/lroff/textout.x
+        Modified to eliminate the ENTRY point.  (9/24)
+
+sys/fmtio/ctotok.x
+        Local variable numch never used (this is old code so I don't know
+        why no other compiler has found this).  (9/24)
+
+sys/fmtio/evexpr.y
+sys/fmtio/evexpr.x
+        The second argument (a debug flag) to yyparse (xev_parse) is a
+        boolean, but xev_parse was being called elsewhere with an integer
+        argument.  Changed to a boolean since the Y*cc code contains many
+        if (yydebug) constructs.  (9/24)
+
+sys/etc/main.x
+        FREDIR is a subroutine but was being called as a function in one
+        place in this file.  (9/24)
+
+sys/tty/ttyputl.x
+        This file contained a statement  call putci (fd, "_")  which was

+        be integer.  (9/24)
+

+
+sys/libc/qsort.c
+        The static function qst() was being used before being declared,
+        resulting in an extern/static declaration inconsistency.  (9/24)
+
+sys/ki/irafks.x
+        The "task irafks = onentry" was incorrect since ONENTRY is an integer
+        function.  This was harmless since the purpose of the task statement
+        was merely to get an iraf main, but I set up a dummy t_irafks task
+        to avoid the type clash.  (9/24)
+
+pkg/cl/bkg.c

+End of revisions merge from A/UX GCC/ANSI-C/F2C work.
+
+dev/graphcap
+dev/devices.hlp
+	Output can now be directed to the default UNIX `lpr' device using
+	any of the aliases "lpr", "lp", or "lw".  The actual device is
+	defined by the value of PRINTER if defined in the user's environment,
+	else is the "lp" device in /etc/printcap.  (9/23)
+
+	(lw is no longer an alias for the NOAO/Tucson device lw1)
+
+pkg/images/iminfo/t_imstat.x
+pkg/images/doc/imstat.hlp
+	Corrected a bug in the mode computation in imstatistics. The parabolic
+	interpolation correction for computing the histogram peak was being
+	applied in the wrong direction. Note that for dev$pix the wrong answer
+	is actually closer to the expected answer than the correct answer
+	due to binning effects.  (LED 9/24)
+
+unix/hlib/iraf.h
+unix/hlib/libc/xnames.h
+	Added the following name redefinitions.  On systems where Fortran and
+	C share the same name space these can cause name collisions.  (9/28)

+Started a full bootstrap and recompile for the sparc architecture.  (9/28)
+
+sys/fmtio/tokdata.inc
+	Deleted the DATA statement for numch, which is no longer used by
+	ctotok.x, the routine which includes this file.  (9/29)
+
+lib/plset.h
+	Added PL$T_LEN defines for type long, required for the generic
+	expansion of plglr.gx in PLIO.  (9/29)

+pkg/images/imarith/mkpkg
+pkg/images/imarith/imsum.gx
+pkg/images/imarith/generic/mkpkg
+pkg/images/imarith/generic/imsum.h	-
+	Images failed to link, with all the imsum externals reported as
+	undefined externals.
+	1. Edited imsum.gx and changed `include "imsum.h"' to `include
+	"../imsum.h"'.
+	2. Deleted generic/imsum.h and the code in imarith/mkpkg which
+	generates it.  There should not be multiple copies of global header
+	files.
+	3. Rebuilt the generic/mkpkg using mkmlist, to ensure that the
+	library list is correct (all the imsum entries were missing).  (9/29)
+
+noao/artdata/mkheader.x
+	1. Fixed a "local variable ua never used" warning, caused by some code
+	being commented out.
+	2. I was also surprised to see the construct `fd = immap (fname, ...)'
+	in this file.  FD means file descriptor whereas immap returns an
+	image descriptor.  FNAME means file name but an image name is not a
+	file name.  FD is declared pointer in this file but is used later in
+	the same routine to hold a file descriptor, which is an integer.
+	This code is illegally accessing the user area of the image header.
+	(9/29)
+
+noao/twodspec/longslit/illumination.x
+	This file failed to compile, with the following errors:
+	    local variable "clgeti" never used
+	    attempt to use undefined variable "im"
+	    attempt to use untyped function "clgetr"
+	1. Changed the call to clgetr to a call to clgeti, since the
+	parameter being fetched is integer.  Added a declaration for im.
+	2. In the process of doing this I noticed that in the call
+	    iferr (axis = imgeti (im, "dispaxis")) {
+	the variable IM was being used before being initialized (or declared).
+	I changed the "im" to "in" but couldn't be certain this was correct
+	since there are two input image pointers (I think; I couldn't be
+	certain they were both input since there are no #[IOU] markers in the
+	comments).  (9/29)
+
+noao/twodspec/longslit/response.x
+noao/twodspec/longslit/fluxcalib.x
+	Similar construct.  Changed calls to clgetr to clgeti in both
+	routines.  (9/29)
+
+unix/hlib/extern.pkg
+	All the digiphot packages failed to link, due to the cross link
+	against the V2.9 versions of the TABLES libraries (due to the
+	recent name changes in iraf.h all code has to be recompiled for
+	V2.10).  I temporarily created a local copy of TABLES in
+	/u3/extra/tables and compiled this with V2.10.  (9/29)
+
+bin.sparc/S5.e
+bin.sparc/S6.e			+
+	Installed the V2.9.3 version of S5.e (the V2.9 shared image) from ursa.
+	S6.e is the V2.10 shared image.  (9/29)
+
+unix/boot/xyacc/mkpkg.sh
+	Added a rm -f *.o to delete the xyacc objects after a bootstrap. (9/29)
+
+---------------------------------------------
+Begin f68881 bootstrap and full sysgen-recompile.  (9/29)
+
+sys/ki/koscmd.x
+	The output spool file on the local node was being opened with zopntx,
+	but written to with kputtx with an invalid channel descriptor, causing
+	the output to be lost when attempting to redirect the output.  The
+	fix was to change the call to kputtx to a call to zputtx.  (9/30)
+
+dev/imtoolrc			+
+unix/hlib/install
+	Copied imtoolrc into dev so that the frame buffer entries in graphcap
+	and imtoolrc can be more easily maintained together, and so that
+	the user does not have to modify a source directory (unix/sun) in
+	order to change a runtime configuration file (imtoolrc).  Modified
+	the install script to make /usr/local/lib/imtoolrc a link to the
+	file in DEV, instead of a copy of the file.  (9/30)

+
+unix/os/zawset.c
+	Added SYSV support.  (10/02)
+
+unix/os/zfiopr.c
+	Added SYSV support (vfork is defined as fork).  On Sun systems
+	<vfork.h> is conditionally included.  (10/02)
+
+unix/os/zgtenv.c
+	Replaced a comment within a comment construct (example from <iraf.h>)
+	by a version which substitutes @ for *, to avoid GCC warning messages
+	about a possible problem with nested comments.  (10/02)
+
+unix/os/zopdpr.c
+	Added SYSV support for vfork/fork as above, plus nice() is used

+
+unix/boot/spp/rpp/rpprat/gtok.r
+unix/boot/spp/rpp/rppfor/gtok.f
+	Commented out the declaration for the unused variable "digits". (10/02)
+
+math/gsurfit/mkpkg
+	Contained a statement $ifeq (USE_GENERIC, YES) which was incorrect,
+	as a lower case "yes" is required since $ifeq uses a simple string
+	comparison.  I noticed this because a bug had been fixed in a .gx
+	file, but was still present in the real/double files, which had not
+	been modified since 1987.  (10/02)
+
+math/nlfit/nlfitdefr.h
+math/nlfit/nlfitdefd.h
+math/nlfit/nlzero.gx
+	Corrected several bugs in the way the aclr$t routines were being
+	called in the nlzero(rd) routine. (10/3/91 LED)

+pkg/plot/phistogram.x
+	Corrected some type mismatch problem in calls to gset. (10/3/91 LED)

+sys/gio/ncarutil/pwrzt.f
+        Variables HIGH,WIDE,WHITE, and LNGTH not used (same problem in

+
+sys/ki/koscmd.x
+	In the call to zopntx to open the local spool file (when redirecting
+	the output), the unpacked version of the filename was being used
+	instead of the packed version required by the kernel routine.  (10/05)
+
+pkg/plot/crtpict/calchgms.x
+	Changed the declarations for the variables min_val and max_val in
+	the procedure crt_user_hgram from int to short. (10/5/91 LED) 
+		 
+dev$hosts
+	Added felis to dev$hosts for Shopbell. On tucana only since irafks.e
+	on felis seems quirky.  (10/5/91 MJF)
+
+pkg/dataio/fits/fits_rpixels.x
+        1. The rfits task has been modified to accept a short last record, i.e.
+        a last record that has not been padded out to 2880 bytes, without
+        generating any warning messages. Short last records were only a
+        problem for IRAF 2.9 when the blocking code was rewritten.
+	(10/8/91 LED)

+	being subtracted from the sum instead of a 3.0 (10/11/91 LED)
+
+unix/boot/spp/xc.c
+	Minor typo in run() code.  (10/11)
+
+pkg/dataio/fits/fits_cards.x

+	I have been holding off on installing this for a couple of weeks
+	in the hopes of finishing the planned work, but rather than delay
+	longer I have installed this version, to be updated later.  The
+	main changes or new features are as follows.
+
+	1. Screendump parameters (R_DISPOSE etc.) are now in the setup panel.
+	2. A number of new builtin lookup table options (e.g. HEAT) have
+	been added.
+	3. User defined lookup tables are now supported.
+	4. Updating of the global screen colortable is now a setup panel
+	option.  This allows it to be turned off, which makes imtool
+	better behaved under openwindows.
+
+	Features not yet in are EPS support, more flexibility in the use
+	of FIFOs, and maybe socket support.  (10/20)

+dev/tapecap
+	Installed the new magtape i/o subsystem.  I will document this more
+	fully later.  Usage is much as before.  The key file controlling the
+	configuration is dev$tapecap.  A description of the tapecap
+	parameters is given in os$zfiomt.c.  Testing and configuration of
+	the tapecap file is only rudimentary at this point.  I have
+	successfully tested thus far with the DC2000 cartridge tape and
+	floppy disk on lepus, the DAT drive on coma, and the 1/2inch 6250
+	bpi tape on tucana.  There is some confusion (dev$devices out of
+	date) regarding the device entries for the 1/4inch cartridge drive
+	on tucana so I did not complete the tapecap entry for this drive.
+	The driver is new and MTIO has been extensively revised.  The new
+	GTY interface provides a general termcap style database facility
+	which is used for tapecap.  (10/20)
+
+dev/termcap
+	Added a new entry for "xirafhelp".  (11/10)
+
+dev/hosts
+        Added sonoma to the hosts file on tucana and ursa.  (11/13 jb)
+
+pkg/plot/t_graph.x
+plt/plot/doc/graph.hlp
+	1. Local variables overplot,append in t_graph were declared int
+	but were used everywhere as bool.
+	2. Missing .le in help page entry for overplot.  (11/20)
+
+lib/fio.h
+	Added a comment for LEN_RAWCMD.  (11/20)
+
+lib/fset.h
+sys/fio/fseti.x
+sys/fio/fstati.x
+unix/hlib/libc/fset.h
+	Added a new fset option F_IOMODE.  The value field is a bit flag
+	consisting of either IO_NORMAL (normal line by line i/o with echo)
+	or some combination of, currently, IO_RAW and IO_NDELAY.  F_RAW is
+	also still defined and if used in a fseti call will set F_IOMODE
+	to IO_RAW with IO_NDELAY disabled.  On a fstati query, F_RAW checks
+	if IO_RAW mode is set, and F_IOMODE returns the i/o mode as a bit
+	flag integer word.  (11/20)
+
+	[Note - the fset integer codes were modified.  This will require
+	[that all layered software which uses fset/fstat be recompiled.]
+
+sys/etc/prpsio.x
+	Testing revealed that while both raw mode and NDELAY (nonblocking
+	i/o) worked from a stand alone process, and raw mode worked from
+	a subprocess, NDELAY would not work from a subprocess.  This was
+	due to the prpsio code, which must check for the i/o mode control
+	strings and make a local fseti call if these are seen.  The prpsio
+	code would set raw mode but was ignoring NDELAY, hence setting
+	IO_RAW+IO_NDELAY in a subprocess would result in only raw mode
+	being set in the pseudofile i/o control process (the CL).  (11/20)
+
+sys/tty/ttyread.x
+	Modified to set F_IOMODE rather than F_RAW.  Since this routine
+	uses NDELAY it it worth updating to use the new bit flags.  Most
+	of the old VOS code still uses F_RAW=(YES|NO), which is fine so
+	long as only raw mode is being set.  (11/20)
+
+pkg/cl/mkpkg
+	Added <libc/fset.h> to the header file dependency list for
+	history.c.  (11/20)
+
+sys/tty/mkpkg
+	Entry in library dependency list for ttygsize.x was incorrect;
+	rebuilt list with mkmlist.  (11/21)
+
+dev/graphcap
+dev/imtoolrc
+	Added imt13-16, imttall128 (128x1056), imttall256 (256x1056),
+	imtwide128 (1056x128), and imtwide256 (1056x256) for use in
+	spectroscopy at request of KPNO.  Also added aliases for the new

+	if it wishes to save a particular system.  This applies only to

+unix/os/zfiomt.c
+	1. RE now causes a read error to be ignored not only when positioning

+
+sys/mwcs/wfsin.x
+	The forward transform now checks for a negative value before taking
+	a square root.  (12/06)
+
+unix/os/zfiomt.c
+	Installed a new version of the new magtape driver which adds
+	support for status output to a TCP/IP socket.  I also have a new
+	program XTAPEMON (not currently installed in IRAF) which listens
+	on a socket and accepts connections from the the new driver (or
+	any similar client) displaying tape status messages in a window
+	on any X server while the drive is being accessed.
+
+	Status output may be directed to either a file or a socket, using
+	the syntax ":so=foo:".  If foo is an absolute pathname beginning
+	with / then output is to a file (this field is interpreted by the
+	unix driver so we are talking about unix pathnames).  Otherwise, the
+	field is assumed to refer to a socket of the form ":so=[host][,port]",
+	e.g., ":so=lepus:", ":so=lepus,5138", ":so=,2345:", and so on.
+	If no host is specified localhost is assumed.  If no port is
+	specified the default port is used.
+
+	In practice, the minimal specification is ":so:".  This will cause
+	the drive to atempt to open a socket connection to the default port
+	on the local host.  If no server is registered the connection will
+	fail harmlessly.  If xtapemon is running on the local host it will
+	accept the connection.  Currently, xtapemon supports multiple
+	concurrent servers (using consecutive port numbers) but the driver
+	does not, unless the port number is given explicitly.  Multiple
+	clients are allowed to access the same server, e.g., multiple
+	processes in the same process tree.
+
+	Note that status output, if enabled, is output in an ascii text
+	stream to either a socket or a file (including things like
+	/dev/ttyX, /dev/tty, /dev/console etc. as well as disk files).
+	Hence the xtapemon utility, while useful for workstations running X,
+	is not required in any way to use the new magtape system or even to
+	view status output.  In the simplest case, "devstatus" may be used
+	to print the drive status.  (12/15)
+
+unix/os/zopdir.c
+	The zopdir routines were modified to read the UNIX directory into a

+	VOS routine).  UNIX directories are not stored in sort order on
+	disk, and previously, IRAF routines which read directories to
+	produce file lists but which did not sort the list for some reason,
+	could produce what appeared to be randomly ordered lists (for
+	example, in image templates).
+
+	A practical result of this revision is that dir sort- will produce
+	a listing which is sorted across the columns rather than along the
+	columns.  This may be preferable when listing very large directories.

+	The calling sequence for ONENTRY was modified to add a third

+	provide an alternative to the normal iraf process level command

+dev/irafhosts           +
+unix/os/zfioks.c
+sys/ki/irafks.x
+        Totally new networking driver.  This version supports both RSH and
+        REXEC connection protocols.  The default RSH protocol avoids
+        password prompts.  In addition, a feature is provided to spawn a
+        daemon process in.irafksd which makes it much faster to fork a new
+        kernel server, once the first RSH connection to a server node has
+        been made.  The new kernel server is largely backwards compatible
+        (although due to magtape i/o changes V2.10 networking cannot be used
+        with older systems anyhow).  The new driver still uses a .irafhosts
+        file, but it need not contain passwords, and the file is automatically
+        created and read protected.  Details to follow.  (12/26)
+
+	Here is some more information on the new networking system (12/31).
+
+	The new driver support three different connection protocols.  The
+	default protocol uses rsh|remsh to spawn a networking daemon which
+	is used thereafter to start iraf kernel server processes on that
+	node (more on the this later).  This is the most efficient protocol,
+	and does not require any passwords.  A rsh only protocol is also
+	supported which requires a rsh connection every time a connection is
+	made.  This is slightly more secure than the rsh/daemon protocol but
+	considerably less efficient.  Finally, the old rexec protocol is
+	still supported.  This is what is used if a password is given for a
+	node in the .irafhosts file.  It is also now possible to use iraf
+	networking even if no rsh or rexec service is available, by manually
+	starting the iraf networking daemon on a server node.
+
+	The rsh/daemon protocol works as follows.  The client calls the
+	zfioks driver to open a connection.  zfioks reads the irafhosts file
+	and determines that the rsh/daemon protocol should be used for the
+	named host.  zfioks attempts to connect to the daemon process on the
+	remote host.  If the connection is made the client passes its port
+	number and an authorization code to the daemon, the daemon forks to
+	create a new irafks kernel server, which then connects to the client
+	via the client supplied port number, and the connection is made.  If
+	the client cannot connect to the daemon, the client forks and execs
+	the rsh task which is used to start up the daemon process on the
+	remote host.  The client can then connect to the daemon in the usual
+	way.
+
+	When the daemon is first started with rsh, the client passes a
+	unique long integer authorization code.  All subsequent connections
+	to the daemon must supply the same code or the connection will be
+	refused.  The authorization code is given in the irafhosts file.
+	Since this networking scheme avoids any suid root processes, the
+	daemon process runs with the uid of the user whose client issued
+	the original rsh request to start the daemon.  Each user has their
+	own daemon process on each server node.  The daemon is started
+	automatically when the first connection is made.  After a certain
+	period of inactivity (default 1 hour) the daemon process will exit.
+
+	Once a daemon has been started with rsh (this takes several seconds)
+	a network connection can be made very quickly, as all that is
+	required is a connect to a remote socket, a fork of the daemon
+	process, and a connect back to the client supplied socket.  The
+	irafks server and the client zfioks driver will then be directly
+	connected via a socket.  The daemon process is just the usual
+	irafks.e running as a daemon, which is why it only needs to fork to
+	spawn a new irafks server.  Only one daemon process is required per
+	user per server node, but there can be any number of irafks
+	servers.  Any number of client hosts can connect to a single server
+	host via a single daemon process, provided the user has set up a
+	.irafhosts with the same authorization code on each client node (if
+	this is not done the connection will still be made, but will require
+	an expensive rsh connect on each call).
+
+	The new driver still uses the .irafhosts file, although most of the
+	motivation for including passwords in the file is gone.  The
+	.irafhosts file is required and will be created automatically by the
+	system if not present.  If an old style .irafhosts file is present
+	it will be replaced by the new version of the file.  The system
+	automatically read protects the file.  The .irafhosts file contains
+	three regions:  some header comments, some keyword=value networking
+	parameters, and the user supplied host list.
+
+	The irafhosts keywords are as follows.
+
+	port		The TCP port number used by the daemon process.
+			Normally set to "default", which tells the driver
+			to assign a port for each user based on HIPORT
+			and the user uid code.  If PORT is set to "none"
+			use of the daemon is disabled and rsh will be used
+			for every connect (this is provided in case someone
+			doesn't feel the authorization code scheme is
+			secure enough).
+
+	auth		The user authorization code.  Set to "default" in
+			dev$irafhosts, but replaced by a unique authorization
+			code when the user uses networking for the first time
+			and the .irafhosts file is created.
+
+	hiport		Used to dynamically assign unique port numbers
+			(see "port" above).  hiport defines the top of the
+			reserved port region used for the irafks daemon.
+			Normally set to "default" (47000).
+
+	timeout		The idle time in seconds after which the daemon
+			will exit.  Normally set to "default".  The builtin
+			default timeout is 1 hour.
+
+	The format of a host-list entry is as follows.
+
+		host-name  ":" login-name password
+
+	The default host-list entry is the following.
+
+		*  : <user> <user>
+
+	This enables the rsh/daemon protocol for all server nodes.
+	The login-name field may be set to "none" to disable networking
+	for a node, or to the actual user login name to cause the
+	connection to a node to be made with different login name than
+	that of the user on the local host.  Setting the password field
+	to an explicit password causes the rexec connect protocol to
+	be used for that node.  Setting the password to "?" causes the
+	driver to prompt for the password, after which the rexec protocol
+	is used to make the connection.
+
+	In actual practice, all of this is automatic and the user never
+	needs to look at or modify the .irafhosts file, unless they want
+	to customize things.  Once the .irafhosts file has been created
+	by the system it should be copied to the user's login directory
+	on other nodes in the local network.  If this is not done iraf
+	networking will still work, but will be less efficient if iraf
+	clients running on different hosts try to connect to the same
+	server (they will have different authorization codes and the
+	driver will have to fall back on the rsh connect protocol for
+	every connection).
+
+	The system template irafhosts file is dev$irafhosts.  The iraf
+	system manager can set the default network parameters in this file
+	if they don't like the builtin defaults.  Note that the hostlogin
+	file is no longer used.  It was confusing for the files to have
+	different names so dev$hostlogin was replaced by dev$irafhosts.
+
+	COMPATIBILITY.  By default the system will try to use one of the
+	rsh protocols, hence the server as well as the client must be
+	running v2.10 iraf.  To connect to a pre-v2.10 server from a v2.10
+	client the rexec protocol must be enabled by setting the password
+	field in the irafhosts file.  A v2.9 client should be able to
+	transparently connect to a v2.10 server.  In all cases where v2.9
+	and v2.10 clients and servers are being mixed, remote magtape
+	access cannot be used since the protocols have changed in v2.10.

+

+        Fixed a couple of problem in the zfiomt server code which were
+        preventing magtape i/o from working over the network.  The server

+
+unix/os/zfioks.c
+	Fixed a bug that was causing remote device allocation/deallocation
+	to fail, when accessing a device over the network.  SIGCLD was
+	being received by the server when the alloc.e terminated and was
+	executing a longjmp to a stack frame that no longer existed (the
+	zfioks driver, with all its forks, has several parallel execution
+	paths all in the same code).
+
+	With this fix remote magtape access seems to be working again using
+	the new magtape and networking drivers.  (12/30)
+
+unix/os/zfiomt.c
+	For a read (zzrdmt), the recsize output to the status output was

+	1. An interface summary was added to the README file.
+	2. Revised MTIO to add a number of new externally callable user
+	routines.  The following is excerpted from the README file.
+
+		yes|no = mtfile (fname)		# Is fname a magtape device?
+	  yes|no = mtneedfileno (mtname)	# No file number given?
+		    gty = mtcap (mtname)
+			mtfname (mtname, fileno, outstr, maxch)
+
+		        mtparse (mtname, device, fileno, recno, attrl, maxch)
+		       mtencode (mtname, maxch, device, fileno, recno, attrl)
+
+		    fd = mtopen (mtname, acmode, bufsize)
+		       mtrewind (mtname, initcache)
+		     mtposition (mtname, file, record)
+
+	Use CLOSE to close a file descriptor opened with mtopen.
+	Use GTYCLOSE to close a termcap descriptor opened with mtcap.
+	MTNAME is the full magtape device specification, i.e, "mt[...]".
+
+	The new routines are MTCAP, MTNEEDFILE, MTFNAME, MTPARSE, and
+	MTENCODE.  MTCAP opens the GTY descriptor for the device specified
+	in mtname.  MTNEEDFILE tells whether a file number is specified in
+	the given mtname.  MTFNAME constructs a magtape file name, given an
+	existing mtname and a file number.
+
+	The MTPARSE and MTENCODE routines are lower level and are provided in
+	case a mtname needs to be edited or constructed which the simpler
+	routines given above cannot deal with.  MTPARSE parses an mtname
+	into the device name, file and record numbers (set to ERR if not
+	given) and tapecap attribute list, if any.  MTNAME does the reverse,
+	building a mtname from these pieces.  (1/02)
+
+dev/tapecap
+unix/os/zfiomt.c
+	Added a new capability "fb" to tapecap.  This specifies the default
+	FITS block factor for each type of device.  (1/02)
+
+unix/os/zfioks.c
+	1. Tested the password prompting option (password = ?).  Fixed a
+	bug in the SysV version of the password prompting code.
+	2. Tested the in.irafksd idle-timeout feature, seems to work.
+	3. Added a timeout feature to the handshaking that goes on between
+	client and server during a connect.  The connect will now fail and
+	shutdown automatically if there is no response for 45 seconds during
+	a connect (e.g., because the guy on the other end is not what we
+	expect it to be).  (1/02)
+
+sys/qpoe/qpiosetrg.x
+	Changed the dimension of the VS, VE input array arguments from "ndim"
+	to "ARB".  (1/07)
+
+sys/etc/xgdevlist.x
+	Added a call to ki_xnode to propagate the network node prefix, if any,
+	to the output resource string.  (1/07)
+
+sys/ki/irafks.x
+	The devpos struct (position information) was not being passed back
+	properly when closing a magtape device opened for network access.
+	(1/07)
+
+sys/mtio/mtparse.x
+	When called with sz_attrl=0, could write to attrl[0] (write off the
+	beginning of the array).  Zero is of course not a legal index, but
+	the routine should be able to accept it as a size, indicating that
+	the attrl string is not desired.  In cases like this the application
+	must still allow space for 1 char of output, e.g., the EOS.  (1/08)
+
+sys/mtio/mtrewind.x
+sys/mtio/mtposition.x
+	These routines were constructing the magtape device name in order to
+	position to a specific file, but were discarding the attrl field,
+	preventing use of tapecap attributes on the command line in a rewind.
+	Changed to use mtfname to construct the device name.  (1/08)
+
+sys/ki/irafks.x
+	Modified the debug output logging code to print more of the ARG

+
+sys/ki/kzrwmt.x
+sys/ki/kzopmt.x
+sys/ki/kopdpr.x
+sys/ki/kgfdir.x
+	These routines were not computing the value of p_sbuflen correctly.
+	This can affect optional string arguments passed in the networking
+	packet header.  (1/08)
+
+unix/hlib/irafuser.csh
+	Changed the definition of mkz to link "-z -/Bstatic".  Omitting the
+	-Bstatic has caused too much trouble on SunOS, when linking on one
+	version of SunOS and executing on a different version.  (1/08)
+
+unix/hlib/login.cl
+	Added a definition for the convenience alias "cls" (unix clear;ls)
+	to the template login.cl.  (1/08)
+
+sys/mtio/mtopen.x
+sys/mtio/mtcache.x
+sys/mtio/mtrdlock.x
+	Modified to pass the mtname parameter though to mtallocate, which
+	can be called by mtrdlock.x in some circumstances.  (1/08)
+
+unix/os/zfiomt.c
+	1. Repeated calls to mtexamine on the same tape would result in the
+	tapeused value incrementing slightly in each iteration.  This was
+	due to the space for the last (EOT) filemark being counted in each
+	read of the tape.  The problem would only show up on some drives;
+	this was because the file mark size is only set to a nonzero value
+	for some devices in tapecap.
+	2. Modified the driver to record the checksum of the status output
+	device, and check to see if the device has changed when the driver
+	is opened repeatedly.  It will now automatically (witout flpr)
+	detect any changes and close and reopen the status device.
+	3. Status output to a file is now enabled if there is a / anywhere
+	in the filename, not just as the first character.  Hence, :so=./file
+	would write to a file in the current directory.  (1/08)
+
+sys/mtio/mtgtyopen.x
+	Modified to permit inclusion of device capabilities in the tapecap
+	definition.  The syntax of a tapecap environment definition is now
+	<tapecap-file><device-capabilities>, e.g., "home$tapecap:so".  Either
+	field can be omitted.  For example,  set tapecap = ":so=host"  would
+	cause MTIO to use the default tapecap (dev$tapecap) but enable
+	status output to the named host for all magtape operations.
+
+	Device capabilities can now be specified in the tapecap device
+	entries, in the tapecap environment variable, or on the command line
+	(as in "mta[:so=host]").  The precedence is the command line, which
+	overrides everything, the tapecap environment variable, which
+	overrides the tapecap file entries, and the tapecap file entry
+	(followed lastly by the builtin defaults where applicable).  (1/09)
+
+unix/os/zfioks.c
+	1. Modified the rsh based connect code to add a fallback to rexec
+	(with a password prompt) if the rsh fails for any reason.  If the
+	connect succeeds, the daemon process will still be started as with
+	rsh, hence all further connects will suceed by direct connection to
+	the daemon.  In practice, what this means is that if an attempt is
+	made to connect to a node to which rsh cannot connect (e.g., because
+	there is no entry in hosts.equiv on the server node), the system
+	will print "access denied", prompt for the user password, and then
+	connect normally.  Subsequent connects will succeed immediately,
+	without any further password prompts, until the daemon process times
+	out and shuts down.
+
+	2. If the integer variable "KSAUTH" is defined in the user
+	environment, the value of "auth" in the user .irafhosts file is
+	ignored and the environment value is used instead.  This makes it
+	possible to dynamically assign authorization codes in the user
+	environment at login time, if someone doesn't like having their
+	kernel server authorization code in the .irafhosts file.  (1/10)

+	The NOAO package is present but is commented out.
+	2. The USER package was redone, adding many common unix tasks
+	as foreign task aliases.
+	3. The CL parameter showtype is now initialized to yes, causing
+	packages and psets to be marked in package lists.  (2/08)
+
+pkg/images/tv/mkpkg
+unix/hlib/mkpkg.inc
+	Added a USE_IIS conditional.  This can be set to "no" in mkpkg.inc
+	on systems where the IIS package will not be used, to avoid trying
+	to build the package.  (2/10)
+
+pkg/cl/cl.par
+	Updated the value of the version parameter to V2.10BETA (should have

+
+unix/hlib/login.cl
+pkg/cl/cl.par
+pkg/images/images/cl
+	Set up a mechanism to automatically detect and warn about out of
+	date login.cl files.  A new parameter "logver", for login.cl file
+	version, was added to cl.par, with the default value being the null
+	string.  The real value is set by an assignment in the login.cl.
+	When the IMAGES package is loaded, images.cl compares the value of
+	cl.logver with cl.version and complains (harmlessly) if there is a
+	mismatch, suggesting that `mkiraf' be used.  It is a bit of a kludge
+	to use images.cl for this, but it is a simple technique and should
+	work fine, since it is unlikely that anyone using IRAF will not be
+	loading the IMAGES package at some point (clpackage.cl and system.cl
+	cannot be used as they are read too early in the load cycle, and
+	obviously login.cl cannot be used).  If there is any question about
+	the comparative dates of IRAF and the user's login.cl this can be
+	determined by executing "lpar cl" after the CL starts up.  (2/10)
+
+	It is very important with V2.10 that the new login.cl be used.

+imio/iki/oif/oifopix.x
+imio/iki/oif/oifupdhdr.x
+imio/iki/oif/oifopen.x
+	A couple of changes were made to improve error recovery for OIF
+	format images, in the event that a task aborts before an image
+	creation operation completes.  Previously this could leave a pixel
+	file behind with no associated header file.
+
+	1. The header of a new image is now updated at open time and at
+	pixel file create time, as well as when the image is closed.  A
+	legal image results even if the operation is aborted before the
+	pixel file is created, or before writing the pixel file completes.
+	2. The header file is now closed after the immap for new images
+	and read-write images, as has always been the case for read-only
+	images.  The header is reopened as necessary when updated.  In the
+	case of a new image, it is necessary to close the header or the
+	header file will be deleted by FIO if the task aborts before the
+	file is completed and closed.  Closing the header of a new image
+	also frees a file descriptor, and important consideration for
+	applications that open many images.  (2/11)
+
+unix/os/zfprot.c
+	The protection code will now silently clobber any existing ..foo
+	file entry when protecting file foo.  There is a slight risk in
+	this, but it should be miniscule as .. prefixed files are very
+	rarely encountered (other than for IRAF image header file protection).
+	Also, the clobber can only occur when a file is protected, a rare
+	operation in itself except for OIF format images.  (2/11)
+
+sys/gty/gtyopen.x
+	Modified to allow a device entry input as a character string to be
+	opened on a GTY descriptor.  The routine already permitted a caplist
+	to be input which would override selected fields of the named device
+	entry, so the change was to allow the termcap file and device entry
+	name to be omitted.  This routine is a useful corollary to GTYCAPS;
+	gtycaps takes an open GTY descriptor and returns the device
+	capability list (caplist) as a string, and gtyopen can now be used
+	to take the caplist and open another descriptor on it.  This makes
+	it possible to store device entries in any form, not just in termcap
+	file form.  (2/12)
+
+sys/mtio/mtcap.x
+	Fixed a bug in this routine.  MTCAP takes a magtape device
+	specification as input and returns as output the GTY tapecap
+	descriptor corresponding to the named magtape device.  The problem
+	was that it was calling mt_gtyopen and returning the gty descriptor
+	returned by this routine directly to the client.  The client
+	subsequently calls gtyclose to free the descriptor, but mt_gtyopen
+	is used within MTIO to cache the most recently referenced tapecap
+	device entry.  When the client closes the descriptor the cache is
+	left pointing to a nonexistent descriptor.  The routine was modified
+	to call GTYCAPS to get the caplist of the cached descriptor, then
+	open a new descriptor on this with GTYOPEN.  (2/12)
+
+sys/imio/iki/oif/oifrename.x
+	This routine calls immapz (what a kludge) to open the image header
+	and read/edit the pixel file name.  A minor modification was required
+	to preserve the header file name in the descriptor to allow the
+	subsequent header update to succeed, now that the header file is
+	closed and reopened for updating.  (2/13)

+unix/hlib/mkpkg.sf.SUN3
+	Installed a custom Sun version of the IEEE-floating to native-floating
+	conversion routines.  The code is actually fairly portable SPP code,
+	but includes Sun Fortran escapes used for NaN mapping.  The routines
+	iee[sg]nan[rd], used to set|get the reserved (native) magic value
+	used to replace or match NaNs, are now functional (formerly they
+	were stubbed out for SunOS).  On Sun-3s and Sun-4s, which are IEEE
+	and unswapped, the only function of the IEEE conversion routines
+	is to map NaNs to and from the reserved (ieesnan[rd]) value.
+
+		ieemap[rd] (YES|NO)		# enable/disable NaN mapping
+
+	A new routine IEEMAP[RD] (YES|NO) is used to explicitly enable or

+	and output, for both the scalar and vector conversion routines.

+	The SunOS IEEE conversion package was modified to add support for

+
+	The new routines are as follows.
+
+		 ieestat[rd] (nin, nout)
+		ieezstat[rd] ()
+
+	IEEZSTAT zeros the counters (since there is no "open" procedure in

+	I made one change to the IEEE interface - the calling sequence for
+	IEEMAP[RD] is now
+
+		ieemap[rd] (mapin, mapout)
+
+	i.e., mapping can be enabled independently for input and output.
+
+	The semantics of the IEESNAN routine were also changed slightly.
+	IEESNAN now has the side effect of enabling mapping for both input
+	and output (it did this before) and zeroing the statistics counters
+	(this is new).  Hence, setting the native pseudo-NaN value will
+	initialize the NaN mapping code.  (2/15)
+
+sys/osb/ieee.gx
+	Installed a new version of the "portable" IEEE conversions package.
+	This is identical to the version developed for SunOS, with the code
+	which initializes the IEEE NaN constant commented out (since the way
+	this is done is system dependent).  The new version of the portable
+	ieee.gx includes the new IEEMAP and IEESTAT/IEEZSTAT routines, and
+	if input mapping is enabled is capable of detecting and converting
+	input NaN values to the local pseudo-NaN value.  It will also
+	attempt to convert pseudo-NaN to IEEE-NaN upon output (if mapout is
+	enabled), but since the IEEE-NaN constant is not initialized the
+	output NaN value will be something else, usually zero.  An
+	as$ieee.gx version of the file is required to set the true IEEE-NaN
+	value.  In principle this can be done portably using an integer
+	equivalenced to a floating variable, but the current version does
+	not bother with that (for output; a similar technique is used to
+	recognize NaN values in the input).  (2/15)
+
+pkg/images/tv/display/t_display.x
+	Added a call to IMGIMAGE to strip any image section from the image
+	name stored in the WCS passed to the display server.  Since the WCS
+	output by display refers to the full image matrix ignoring any
+	section, defining the image as a section was incorrect.  The WCS
+	still does not deal correctly with dimensional reduction when
+	displaying images greater than 2 dimensions.
+
+	This was tested with both image raster and QPOE data using RIMCURSOR
+	to generate coordinates and seems to work correctly.  In particular,
+	the correct physical coordinates are generated for QPOE data
+	regardless of the QPOE block factor or image section.  (2/16)
+
+sys/qpoe/qpioparse.x
+	Fixed a bug that was preventing the key=(x,y) (alternate coordinate
+	system) feature of QPIO from working properly.  The code was setting
+	the IO_EVXOFF field twice but was not setting IO_EVYOFF; hence, given
+	a key such as key=(dx,dy), XOFF was being set to DY and YOFF would
+	retain its old value, probably Y.  A reasonable looking image would
+	result but it was the wrong image (we were seeing key=(dy,y)).  (2/16)
+
+sys/imio/iki/qpf/qpf.h
+sys/imio/iki/qpf/qpfwfilter.x
+	Fixed a bug in the code which writes the QPIO filter to the QPF image

+	card.  (2/16)

+	Modified rfits so that the ieee +/-NaNs, and +/-Infs are correctly
+	mapped to a user specified native floating point number. Underflow
+	values are automatically converted to 0.0. A warning message is
+	printed on the terminal if any bad pixels were replaced.  A warning
+	message is also printed if valid floating point pixel values >
+	MAX_REAL or < -MAX_REAL were detected which can happen for both fits
+	bitpix -32 and -64 images.  Imreplace can be used to replace these
+	explicitly. (LED 2/17/92)
+
+pkg/dataio/fits/fits_wheader.x
+	Modified the short_header=yes option in wfits so that the image

+
+pkg/dataio/fits/fits_params.x
+	Modified wfits so that string parameters that are 1) written

+	will have the / in column 33 instead of 2 spaces past the end of the

+	Implemented a scan mode in rfits so that devices which have a slow

+
+sys/imio/iki/qpf/mkpkg
+sys/imio/iki/qpf/qpfwattr.x		+
+	Added a new routine qpf_wattr to QPF.  This is called when an
+	image descriptor is set up for a QPOE image.  The routine checks
+	for the existence of a series of QPOE header paramters "defattr1",
+	"defattr2", etc.  If present, these are string value parameters,
+	the string value specifying the name of a parameter to be added
+	to the output image header, and how to compute the value of the
+	parameter.  For example, defattr1 might have the value
+
+		exptime = integral time:d
+
+	meaning add a parameter "exptime" to the output image header, giving
+	as the value of the parameter the integral of the range-list of
+	attribute "time", type double, of the event attribute expression
+	used to filter the event list used to create the output image.  (In
+	other words, compute EXPTIME, the total exposure time for the
+	filtered image).  Currently, the syntax of the DEFATTRn parameter is
+	very limited and must be similar to that shown in the example, but
+	the parameter and attribute names can be anything, and the datatype
+	can be int, real, or double.  Since the parameter is string valued
+	it will be easy to generalize in the future should we need to do
+	so.  (2/18)
+
+sys/imio/iki/qpf/qpfcopypar.x
+	Improved the error recovery.  (2/18)
+
+pkg/cl/gram.c
+	Constants such as 0:00:60 or even 0:00:59.999999999 could trigger
+	an "illegal constant" error abort in CL scripts, due to round off
+	errors in the CL code.  Technically there is no reason one cannot
+	have a number such as 0:00:60 (or 0:00:any-positive-number for
+	that matter), since the result is well defined, so I relaxed the
+	overly stringent error checking in the gram.c code.  (2/19)
+
+sys/gio/cursor/grcwcs.x
+	The code which computes the scale terms for an axis could die on
+	a divide by zero error when presented with an axis that has no
+	range.  It will now detect the condition and set the scale term to
+	1.0; the value is arbitrary, since there is no range on the axis
+	and deviations from the mean will always be zero.  (2/19)
+
+sys/imio/iki/stf/stfrdhdr.x
+sys/imio/iki/stf/stfwfits.x
+	The STF image kernel was modified slightly to support images with
+	GROUPS=F.  When the FITS image header is read, if GCOUNT=F the
+	parameters GCOUNT, PCOUNT, and PSIZE are initialized as for an image
+	with a single group and no GPB.  The header update code was modified
+	to omit these parameters when updating an image for which GROUPS=F,
+	since the parameters should not be present in the FITS image header
+	if the image unless GROUPS=T.  (2/19)
+
+sys/imio/iki/oif/oifrename.x
+	An image rename operation such as pix.0001.imh -> pix.imh would
+	succeed for the header file but would fail to rename the pixel
+	file.  This would often pass unnoticed using a hidden imdir, but
+	is very evident when using imdir=HDR$.  The problem was due to the
+	use of fnroot in oifrename, in a test to see if the root image
+	name is the same for the rename operation.  This would fails as
+	fnroot cannot descriminate between image extensions and file
+	extensions.  I replaced the calls to fnroot by calls to zfnbrk,
+	to get the root offset and hence strip off any logical directory
+	prefix, which was the point of the original call to fnroot.  (2/19)
+
+unix/os/zfiomt.c
+	It turns out there was still one case where the new magtape driver
+	did not emulate the simple unix model of open, write,write,write,
+	close, open, write,write,write, close, open, etc.  The exception was
+	minor, but caused a problem with the TIB SI driver for the HP drive
+	on a Sun (the only one of these we have seen so far is at STScI).
+	The result was a double EOT between each file on the tape, when
+	appending files with WFITS.
+
+	What was happening is that when the driver was opened to append a
+	file to the tape, it opened the drive read-only to position the
+	tape, then closed it and reopened write-only for writing.  This is
+	done to avoid clobbering the tape if an abort occurs during the
+	file positioning operation.  What was happening was that when already
+	positioned to EOT, the drive would be opened read-only, no positioning
+	would occur since the tape was already at EOT, the drive would be
+	closed, and reopened for writing.  Hence there was an unnecessary
+	open-read/close before writing each tape.  This should be harmless -
+	it does not move the tape or talk to the hardware - but it was
+	triggering a bug in the host driver.
+
+	Evidently (this is my theory at least), this host driver is pretty
+	clever and delays writing the double file mark marking end of tape.
+	So long as you just append files it never write the EOT, until the
+	tape is rewound.  A rewind or backspace should trigger writing of
+	the EOT.  What I think was happening was that the open-read would
+	trigger writing of the delayed-EOT.  The host driver would write
+	two tapemarks and backspace over the second one.  Only problem is,
+	it had already written one (one is always written after every file
+	even with delayed EOT), so you end up with a double file mark, or
+	EOT, between every file on the tape.  This is a blatant bug in the
+	host driver.  We were able to duplicate this using only using UNIX
+	TAR by writing a small C program which did  close(open(/dev/xxx,0));
+	and was called before using tar to append each file.
+
+	As a workaround I have revised the iraf driver to avoid opening the
+	tape read-only for positioning unless some positioning is actually
+	necessary.  If all one does is append files, the positioning open
+	is avoided and the simple unix semantics are exactly duplicated,
+	i.e., all the driver does is open for writing, write the file, and
+	close.  (2/19)
+
+pkg/dataio/fits/fits_write.x

+	Changed the default for the "initcache" parameter from yes to no.
+	initcache causes rewind to "forget" how many files there are on the
+	tape, forcing a rescan the next time one seeks to EOT.   It is
+	arguable whether it is safer to init the tape status cache on a

+sys/osb/ieee.gx
+	Fixed a typo in the generic code for ieevupk - an "amovr" should have

+	to fail for large numbers.  (2/25)
+
+unix/os/zfiomt.c
+	Added a new capability "fe" to tapecap.  This stands for "file
+	equivalent" and is the amount of tape in Kb which, in a file read,
+	is equivalent to a file-skip-forward 1 file operation.  This
+	capability can be used by applications which scan large tapes
+	containing many files to decide whether to read the rest of the
+	file, or close the file immediately and open to the next file (which
+	implies a FSF).  On devices (like some DAT drives) where a FSF
+	operation can be slower than a file read, it is faster to read
+	small files than to FSF to the next file.  If the fe parameter is
+	missing the value is assumed to be zero, meaning that FSF is faster
+	than reading the file.  Note that "fe" is not used by the driver,
+	it is an optional parameter provided for use by tape applications
+	as a device-dependent optimization.  (2/27)
+
+pkg/dataio/fits/fits_read.x
+	Changed the interpreation of the fe parameter as read from

+
+	    onerror_remove (procname)

+	Previously there was no way to deactivate such procedures, other than
+	during error recovery or task termination.  (2/29)
+
+sys/mtio/mtupdlock.x
+	This procedure calls FATAL if an error occurs while updating a lock
+	file.  This was causing problems with magtape error recovery,
+	because mt_sync, which causes the lock files to be updated, is
+	posted by MTIO as an ONERROR procedure.  If an error occurred and
+	the lock file could not be updated, FATAL would abort the task,
+	error recovery would call mt_sync, which would try again to update
+	the lock file, leading to error recursion or errors during error
+	recovery, and various nasty scenarios.  With this change magtape
+	error recovery appears to be working correctly again.  I tried
+	several mtexamine runs, aborting each with a ctrl/c (but omitting
+	the flpr) and the system recovered perfectly each time.  (2/29)
+
+sys/mtio/mtdealloc.x
+	Added calls to mtdeallocate to sync the MTIO cache (update the lock
+	files with the current tape position) and then clear the cache,
+	clearing the entry for the deallocated device as well as forcing all
+	devices to reload their lock files.  This was the source of the
+	problem where allocating and deallocating device A and then allocating

+	were performed without seeing any problems.  (2/29)
+
+pkg/system/rewind.par
+	Changed the default for the initcache parameter back to yes.  It is
+	essential that the cache be initialized when a tape is removed and a
+	new tape mounted, and it more likely that the user will rewind the
+	tape (in software) than that they will deallocate/reallocate.  (3/01)
+
+	rewind init[+|-] appears to be working correctly now, probably as a
+	result of one of the bug fixes made during the period 2/29-3/01.
+
+unix/os/zfiomt.c
+	The tapeused counter is now cleared when opening a tape and the tape
+	position is undefined.  This condition forces a rewind and clears
+	all cached data.  (3/01)
+
+sys/ki/kzopmt.x
+sys/mtio/mtcache.x
+sys/mtio/zclsmt.x
+sys/mtio/zopnmt.x
+	A number of changes were made to these routines during two days of
+	beating on the system with ctrl/c interrupts to improve error
+	recovery.  With these improvements the magtape i/o system again
+	appears to be solid with respect to error recovery.  A tape task can
+	be interrupted either during positioning or during a read and the
+	system should recover completely, without need to do a flpr (I
+	didn't do any flprs during all this testing).  Interrupting a write
+	is ok too, but will leave a partial file on the tape.  Any kind of
+	interrupt will cause the tape position to be marked undefined,
+	forcing a rewind the next time the tape is accessed, and clearing
+	all cached information (clearing cached tape information when an
+	interrupt occurs during a read is not necessary in all
+	circumstances, but simplifies things and is probably safer).
+
+	1. The kzopmt routine (KI) had a serious bug in that it did not
+	allocate a KI channel descriptor until after the device open.  This
+	is ok for most devices, but not for tapes since the device open
+	implies a tape positioning operation which may take a very long
+	time, and hence is suspectible to interrupts.  FIO and MTIO error
+	recovery has to be able to close a tape device which is "partially
+	open", or open read-only for positioning, prior to the i/o operation.
+	The close operation would fail as the kzclmt routine would be
+	expecting a KI channel descriptor but would not get one, causing
+	a bogus file descriptor to be closed.  This would cause the tape
+	close to fail and could in some cases result in a segmentation
+	violation or process panic shutdown.
+
+	2. zopnmt was modified to update the cached file position after
+	the driver open.  This was necessary to mark the cached entry
+	for updating, to allow an undefined position to be written in the
+	event that an interrupt occurred during i/o.
+
+	3. zclsmt required minor changes for both the interrupt-while-
+	positioning and interrupt-during-i/o cases.  In the IWP case mt_sync
+	is now called with a status of ERR to cause an undefined position
+	to be written.  In the IDIO case MT_FILNO = -1 in the internal
+	MTIO descriptor is used to flag error recovery, but due to the
+	calling sequence of the driver open having changed with the new
+	driver, MT_FILNO was being overwritten with a valid tape position
+	during the device close.  This would cause a valid position to be
+	written to the .lok file when a tape operation was interrupted
+	while i/o was in progress.
+
+	4. The file position cache code underwent several subtle modifications.
+	Probably these were not necessary but they bullet-proof the code a
+	little bit.
+
+	The result of all these changes is that, following an interrupt of
+	a tape operation, 1) devstatus should always show file=-1, record=-1,
+	and 2) the next tape operation should cause an automatic rewind
+	followed by a space forward to the indicated file.  It should not be
+	necessary to flush the process cache.  Any other behavior, even if
+	harmless, is considered incorrect.  (3/01)
+
+sys/etc/xalloc.x
+sys/mtio/mtalloc.x
+sys/mtio/mtstatus.x
+	Modified the "devstatus" command to print the tape status file
+	(.lok file) even if the device is not allocated, provided the file
+	exists.  This is desirable since taping is now permitted even on
+	unallocated devices, and it is useful to be able to see the tape
+	status file to see what file the tape is positioned to, how much
+	tape has been used, etc.   If the device has not been allocated
+	devstatus will still issue a warning message to that effect, as it
+	has always done, followed by the contents of the .lok file (tape
+	status file), if such exists.  Since existence of the tape status
+	file no longer necessarily implies that the tape has been allocated,
+	the header message in the file was changed from "Magtape device X
+	allocated to ..." to "Magtape device X status ...".  (3/01)
+
+sys/mwcs/mwshow.x		+
+	Added a new routine MW_SHOW to MWCS.  This is used to print a
+	representation of a MWCS to an output file (usually, for debugging
+	purposes when writing an application).
+
+		call mw_show (mw, out, what)
+
+	The routine does not yet print all that it could about the MWCS.
+	The argument "what" is not yet used.  This routine was described
+	in the original interface but had never been implemented.  (2/25-3/01)
+
+sys/mwcs/mwcs.h
+sys/mwcs/mwsv.h			+
+sys/mwcs/wfinit.x
+sys/mwcs/mwload.x
+sys/mwcs/mkpkg
+	In IRAF v2.10 we increased the max number of WCS attributes, which
+	affected the size of the MWCS descriptor.  This caused the WCS stored
+	in old QPOE files to be unreadable, since it turns out that while
+	the MWCS interface (mw_save) encodes a MWCS descriptor in a machine
+	independent form for external storage, this form is essentially just
+	a copy of the internal MWCS binary descriptor.  When the internal
+	descriptor changed the old saved descriptors could not be read.
+	Since QPOE is a runtime binary format there is no requirement that
+	the files be readable from one version of iraf to the next, but it
+	is desirable to minimize such incompatibilities, or at least detect
+	them and issue an appropriate error message.
+
+	Really fixing this problem in a general way is not easy given the
+	complexity of the MWCS descriptor.  What I did was define a separate
+	MWSV save file descriptor in mwsv.h, deleting the old SV_ entries
+	from mwcs.h.  The old save structure had some extra space in it for
+	just this sort of emergency, which is zeroed out in the old MWCS
+	savefile descriptors.  Fields giving the MWSV version number, number
+	of WCS, and WCSLEN (WCS substructure length) were added to the save
+	descriptor.  Since these fields are zero in the old descriptors the
+	"version number" of these old descriptors is zero.  The mw_load code
+	was modified to use a builtin MWSV version zero value for WCSLEN,
+	and calculate NWCS, allowing it to read these old descriptors.  New
+	descriptors are written using the actual values for NWCS and WCSLEN
+	and a version number of 1.  Hence, the new mw_[save|load] code can
+	both read old descriptors and write and read the new descriptor with
+	its larger max number of WCS attributes.
+
+	I also discovered and fixed a minor problem in the save code.  The
+	SV header (integer) was being read and written directly without use
+	of the MII routines, hence the MWCS save/load code was not fully
+	machine independent.  The appropriate MII routines were added to
+	pack and unpack (byte swap) the save header.  This won't affect
+	existing saved MWCS written on big-endian machines like Sun, since
+	the MII routines merely copy the data on such machines.  (2/25-3/01)
+
+sys/mwcs/mwsctran.x
+	Fixed a typo in the error checking code.  There was a "mw_system"
+	reference which should have been "mw_ssystem".  (3/04)
+
+plot/pltwcs.x
+plot/t_graph.x
+	Modifications were made to produce a label appropriate for the
+	wcs type selected rather than always use the world system label
+	in the image; i.e. if plotting in logical wcs the label is
+	"Logical pixel" rather than something like "Wavelength (Angstroms)".
+	The change affects pcol(s), prow(s), and graph.  (3/04 FV)
+

+	Added solarium and taco to the hosts file on tucana and orion.  Nigel

+        Added two new parameters wxformat and wyformat to the rimcursor task.

+
+sys/mio/mtupdlock.x
+	This, routine, which updates the magtape device status file (aka

+	to update the status file and cause a fatal exit of the task in
+	circumstances where this was not really necessary, for example when
+	the old status file did not exist or could not be read.  This could
+	result in the message "fatal error while closing magtape file".  I
+	modified the routine to recover if the old file could not be read
+	and to take an error exit only if the new status file could not be

+sys/imio/iki/stf/stfaddpar.x
+	The stf_addpar routine is used for a new image or a new copy of a

+	added a parameter is also added to the open image descriptor (image
+	header).  The imaddX calls for the image header would initialize
+	the value of any existing header parameters, causing any existing
+	WCS to be lost (since the standard GPB parameters are for the WCS).
+	The fix was to omit the imaddX call if the named parameter already
+	exists in the image header.  (3/10)
+
+sys/imio/iki/stf/stfaddpar.x

+
+unix/os/zfiomt.c
+	Discovered and fixed another error recovery problem.  During testing
+	using WFITS to write a number of very small images, the program was
+	spending most of the time doing the file close on the magtape device
+	(which writes a tape mark and takes a finite time for such a device).
+	An interrupt would therefore usually occur during the close, resulting
+	in a half-completed file close; error recovery closes open files, and
+	the driver was bombing as part of the descriptor had already been
+	deallocated.  The fix was to modify ZZCLMT to check for a partially
+	deallocated descriptor before proceeding to close the file.  (3/14)
+
+unix/os/zfiomt.c
+	When appending files to a tape, the space for the file mark was not
+	being counted, causing an incorrect tapeused value when writing to
+	DAT or Exabyte.  (3/14)
+
+unix/os/zfiomt.c
+	Added two new tapecap device parameters "ro" and "rr".  If "ro"
+	(rewind-on-open) is set the tape is rewound on every open to get to
+	a known position, after which the driver will space forward to the
+	desired file.  If "rr" (rewind-after-close-readonly) is set the tape
+	is rewound when closed following a readonly operation.  These
+	options are rather drastic, but are provided to deal with drives that
+	leave the tape in an unknown position after a file operation.  (3/15)
+
+	I also looked into the problem of fast techniques for finding the EOT
+	of large tapes containing hundreds of files.  This is important as
+	seeking to the end of tape file by file where are hundreds of files
+	can be very time consuming.
+
+	At least in the case of a DAT with the ApUNIX driver there is no
+	system and driver independent way to do this because the driver does
+	not report an error if one attempts a fsf N where N is greater than
+	the number of files on the tape.  However, such an operation *does*
+	leave the drive positioned to EOT, hence operations with large N can
+	be used to position to EOT or append to a tape.  This is perhaps
+	most easily explained with some examples.  Assume we have a tape mta
+	with 100 files on it.
+
+	    wfits dev$pix mta[999]	appends a file
+	    mtex mta[999]		positions to EOT
+	    mtex mta[998]		after the above, reads last file
+
+	After one of the above operations the driver will report that
+	there are 999 or 998 files on the tape.  A mtex of the full tape
+	would automatically correct this figure.
+
+	Of course if the user knows that there are 100 files on the tape
+	they could just write to mta[101] or read mta[100], and the driver
+	would immediately position to the indicated file using a multifile
+	space operation (if enabled in tapecap).
+
+	Further studies will be needed to determine if there is any way
+	to exploit this sort of drive behavior in the driver to make things
+	transparent to the user.

+
+sys/fmtio/dtoc3.x
+	The DTOC3 code had a very nasty problem which showed up on a specific
+	machine (lepus, mc68882 fp).  There is some code in this routine which
+	goes as follows:
+
+	do i = 1, no_digits {
+	    v = v * 10.0d0
+	    j = v
+	    v = v - j
+		(etc.)
+
+	where V is double and J is integer.  In the case where this failed
+	the number being printed was 6 and upon entry to the above loop V
+	was 0.6 (normalized to 0-1).  The int operation J=V was setting J to
+	5, but the V=V-J was returning 1.0.  In the next loop V was 1 and
+	V * 10 was 10, causing digit conversion to fail, since the value 
+	being digitized must be a single digit.
+
+	In mathematical terms the code was correct but evidently it was
+	failing due to some sort of roundoff problem.  I added some code
+	to try to detect this condition and correct it.  The statement
+	J=V was also replaced by J=INT(V+EPSILOND) to round up numbers
+	which are integral to within the machine epsilon (e.g., 5.99999999
+	with 16 or so 9s becomes 6).  (3/22)

+	in the CLOUT.  The CL (actually prpsio code) would get both in the
+	same read and it was causing some problem which I did not have time
+	to investigate.   Added a call to flush(CLOUT) to avoid the problem,
+	is safer anyway.  (3/22)

+
+unix/os/zfaloc.c
+	Since I was already working on zfaloc I also added a feature to

+	preallocate only the last block of the file, leaving the remainder
+	of the file blocks to be allocated when data is written to the file.
+	Now, if "ZFALOC" is defined in the user's host environment, full
+	preallocation of the file is enabled.  If the variable is defined
+	but has no string value all zfaloc files are fully preallocated,
+	otherwise, the string value is a comma delimited list of substrings,
+	and a file will be fully preallocated only if one of those substrings
+	matches a substring of the file name in the zfaloc call.  This allows
+	files in certain directories or of certain types to be fully
+	preallocated while others are allocated in the normal fashion, so
+	that the behavior of the routine can be customized for a given
+	type of application.  (4/07)

+pkg/cl/exec.c
+	The symptom of this bug was that if a package which has package
+	parameters was loaded at login time and the package parameters were
+	later edited, the edited values would not be used.
+
+	This was traced to a problem with the pfile pointer in the package
+	descriptor pointing to a discarded copy of the package pset.  The
+	PACKAGE command, executed in the package script task when the package
+	was loaded, would quite correctly set up the package descriptor 
+	pointing to the runtime copy of the package pset for the package
+	script task.  When EOF of the login.cl was reached the package
+	script task would terminate and the runtime pset would be copied
+	back to the main package pset and the runtime pset freed - but the
+	package descriptor was left pointing to the old, no longer used pset.
+
+	The fix was to modify oneof() (that's "on-eof"), called when a task
+	terminates, to check if the task is a package script task and if
+	so fix the package descriptor to point to the main pset.  (4/09)

+	routines avoid the varargs stuff, and do automatic type conversion.

+pkg/cl/mkpkg
+	Added the long-awaited ability to scan from a pipe (or whatever the
+	stdin is connected to).  Also added the new formatted scan and print
+	routines scanf, fscanf, and printf.  These are like the unix/stdio
+	versions but use FMTIO, supporting such FMTIO features as %h and
+	%*.*.  For example,
+
+	    cl> printf ("%d foo %g\n") | scanf ("%d foo %g", i, x)
+
+	or
+		while (fscanf (list, "%d %s", i, s1) != EOF)
+		    printf ("i=%d, s1=`%s'\n", i, s1)
+
+	Don't forget the [f]scan routines, which may still be more convenient
+	for simple unformatted scans.
+
+	The new printf routine uses the VOS PARG routines to pass argument
+	operands, hence provides automatic type conversion on output.  If an
+	incorrect number of arguments are passed an incomplete format error
+	will result.  The scanf routine is an interface to the LIBC scanf
+	routine (actually, u_doscan).  The CL scanf/fscanf routines call the
+	LIBC scanf which parses the format string and writes the output
+	values whose addresses are passed in a manually crafted varargs
+	argument list.  Since scanf writes directly into the value fields of
+	the output parameter descriptors, no automatic type conversion is
+	possible and there is no checking for string overflow when writing
+	to a string valued parameter.  Care should be taken to make sure the
+	scanf format matches the datatypes of the output parameters.  (4/11)

+sys/mwcs/mwloadim.x
+sys/mwcs/mwsaveim.x
+	Various changes were made to fix the MWCS "dimension mismatch"
+	problem.  This would happen during an image open (iw_saxmap) when
+	the dimension of the WCS was different than that of the image and 
+	an image section was in use.  The error was being detected in
+	mw_saxmap and was correct, i.e., the routine was being called
+	incorrectly by iw_saxmap, part of the image header interface code.
+
+	Evidently axis mapping was not fully implemented; it worked for
+	runtime read-only maps of an image, but failed when making a new
+	image which was a reduced-dimension section of another image
+	(e.g., imcopy dev$pix[*,10] pix1 would do it).  The new image would
+	retain the original WCSDIM which would not match the physical image
+	dimension when the new image was later opened with a section and
+	a new axis map created.
+
+	The fix was to preserve the axis map in an mw_saveim/mw_loadim
+	operation, and in iw_setaxmap, merge the new axis map for the
+	reduced-dimension image into the axis map associated with the stored
+	MWCS.  A new image header parameter WAXMAPnn was added to store the
+	axis map.  iwsaxmap.x now reads the old axis map of dimension

+	CD matrix to the unitary matrix.  The old code had two bugs: 1) the
+	full WCSDIM dimensioned CD matrix was not being initialized when
+	CDELT/CROTA2 were used instead of the CDi_j notation, and 2) mk_idmd
+	was being used to initialize IW_CD to the unitary matrix of dimension

+	The symptoms of the bug fixed here were as follows: when testing the

+	but rfits make- would fail with a read error.  The failure would only
+	occur the second time the task was run, on the tenth file, and only

+	because, for some reason, the read request being issued by IRAF was
+	not a multiple of the device block size for this fixed block device.
+
+	It took about 5 hours to track this one down as it took a while to
+	find a repeatable test case (I used LOGIPC), and the actual bug was
+	far removed from the read error seen during testing.  What was
+	happening was that the 1) the read error was due to a read request
+	not a multiple of the device block size, 2) the bad read request
+	was due to a device open with no tapecap information (the driver
+	actually works in this case, using all the builtin defaults which
+	are correct for most variable block UNIX devices), 3) the lack of
+	tapecap information was due to an invalid string pointer passed to
+	the zopnmt routine at open time, 4) the bad pointer was due to the
+	real GTY pointer being clobbered by a bug in the mtcache code.  The
+	entire MTIO descriptor was being cached, including the runtime fields
+	as well as the positional fields.  When a cached entry was recalled
+	the GTY pointer stored in the descriptor would be overwritten.  Since

+	3. Made the "setenv iraf" a bit smarter.  iraf is still set to a

+	permission, but some of the new hardware does.  This was causing a

+unix/hlib/install
+	1. Smartened up the code used to guess the iraf root directory.  It now

+	directory actually exists and if not sets the value to (cd ../..;cwd)
+	instead, assuming install is being run from $iraf/unix/hlib.  This
+	latter feature also has the effect of ignoring an incorrect value of
+	$iraf set before running the install script.
+	2. Added a "set hlib = " to the "Set the BINDIRS" section.  An old
+	value of hlib set when install was run would otherwise be inherited
+	ignoring the new value of $iraf set in the script.  (5/02)

+
+unix/os/zfioks.c
+	Fixed a minor bug in the new zfioks code.  If client authorization
+	fails (as when one has different authorization codes in .irafhosts
+	files on different nodes) the driver is supposed to shutdown the
+	old in.irafksd daemon and start another one via rsh for the new
+	authorization code.  This was failing as a status value was not being
+	cleared before doing the rsh.  The rsh would succeed but then the
+	client would see a bad status and give up (unnecessarily), falling
+	back on a password prompt and rexec call to make the connection.
+	It was actually working due to the redundancy in the driver, but
+	due to the bug one would get the unnecessary password prompt for the
+	rexec.  (5/04)

+	as rfits.  Currently the :se capability is only enabled for the QIC
+	drive on ursa, since this appears to be needed only for the ST
+	driver bug seen on this system.  The fb#2000 capability (which avoids
+	file skip operations which cause problems on the QIC drives due to
+	(I think) buffered data being lost) is more generic and harmless so

+sys/imio/iki/iki.h
+	IKI was modified to add a flag word for each driver which can be
+	used to note IKI level characteristics of the different image kernels.
+	This was used to flag that the QPF driver cannot write to or create
+	QPOE images.  In a new copy operation, iki_open will not automatically
+	preserve the image type if the read-only flag is set for the input
+	image type.  Hence, in a new copy of a QPOE image, the type of the
+	new image will be controlled by the imtype environment variable rather
+	than trying to make a .qp image.  For other images types a new-copy
+	operation will preserve the image type as before.  Explicitly giving
+	the image extension for a new image always forces that type of image
+	to attempt to be created, whether it can be created by the image
+	kernel or not.  (5/07)
+
+sys/imio/iki/stf/stfhextn.x
+	This bug was unrelated to the above change but was found during
+	testing (in fact it has been there for years).  In v2.10, "imtype"
+	is set by default, with value "imh".  In an imcopy operation such as
+
+	    imcopy foo.hhh foo2
+
+	the output image preserves the image type of the input image,
+	i.e., an STF image is created.  What was happening was that an STF
+	image was being created named "foo2.imh", since imtype was set to
+	"imh" and this is a legal STF image extension.  I hacked stfhextn.x
+	to ignore imtype if set to "imh".  (5/07)
+
+pkg/dataio/fits/fits_wheader.x
+pkg/dataio/fits/mkpkg

+	Added 'dynamo' to orion, gemini, and ursa.  Primary name is
+	'dynamo.kpno.noao.edu' since this is all it responds to, but made an
+	alias named 'dynamo'.  Not added to Tucana while release being worked 
+	on, I'll do it later.  (5/8/92  MJF)
+
+dev/termcap
+	Made an entry for the machine in Pat Osmer's office, lw8, on gemini,
+	ursa, and orion.  Added to Tucana by JB.  (5/8/92  MJF)
+
+unix/os/zfiomt.c
+	1. Changed the builtin defaults for the maximum and optimum record
+	sizes to 64512.  This is a more conservative value, smaller than the
+	original defaults (maxrec was previously 65535), hence less likely
+	to cause a read error.  The builtin defaults are overridden in most
+	tapecap entries but will be used in user-written tapecap entries
+	which do not set maxrec/optrec explicitly and are likely to rely
+	heavily on the builtin defaults.  The value 64512 is the largest
+	multiple of 1024 less than 65536, and is the minphys value in SunOS.
+	On some devices a read request larger than this value cannot be
+	serviced and will result in an i/o error.
+
+	2. The maxrec value set in tapecap was not being used for file
+	positioning where the driver searches for EOT by skipping a file
+	and reading a record to check for EOT (a read after a fsf which
+	returns zero signals EOT).  On some devices the large read request
+	could cause the read operation to return an error.
+
+	3. If a nonzero maxrec value is set, the driver now guarantees that
+	optrec will not be greater than maxrec (this was not necessary since
+	MTIO does this anyway, but it seems advisable to apply the constraint).

+	Fixed a bug in the definition of variance in the imstatistics

+
+sys/mtio/mtio.h
+	Changed the magtape lock file directory from uparm$ to tmp$.  Storing
+	the lok (magtape position) files in uparm causes problems if the
+	user starts up two concurrent CLs with different uparms, and then
+	tries to command the same device from both CLs.  Since they would have
+	different uparms they would have different copies of the lok file for
+	the device, and MTIO could get confused about the tape position.
+	Years ago, in the early days of MTIO the lok files were moved to
+	uparm to avoid multi-user problems (see below), but the multi-user
+	problem is tractable and less of a problem than the concurrent-CL
+	problem dealt with here.  (5/29)

+sys/mtio/mtclean.x		+
+	Added a new (hidden) system task called MTCLEAN.  This is called at
+	CL startup time to delete old magtape lok files.  Previously the
+	login.cl file would delete these files using "delete
+	uparm$mt*.lok".  This approach is no longer discriminating enough
+	however, when the lok files are stored in tmp$ which is a public
+	directory.  The MTCLEAN task is like "delete uparm$mt*.lok" except
+	that it leaves a lok file alone if it belongs to a different user
+	who currently has the drive allocated.  If the lok file is for a
+	device which is not currently allocated it is unconditionally
+	deleted.  If the lok file belongs to the current user it is deleted
+	only if it is "stale", i.e., older than a certain interval
+	(currently one hour, and a parameter default).
+
+	It is harmless to delete lok files in the sense that MTIO will
+	automatically recover (by rewinding the tape) if the lok file is
+	lost, so it is safest to err on the side of occasionally deleting a
+	lok file which is current.  However, this will only happen if the
+	user has not allocated the drive and someone starts up a CL, or if
+	someone using an allocated drive starts up a second CL and the lok
+	file is older than the "stale" threshold.  (5/29)

+
+unix/hlib/login.cl
+	Several minor changes were made to the template login.cl over the
+	past couple of weeks.
+
+	1. The "stty xterm" statement in if(envget("TERM")=="xterm") was
+	changed to "stty xterm nl=44".  Since xterm does not have a screen
+	size sense query (like gterm) we can't set the screen size correctly,
+	but it is better to set a small wrong value than a large wrong value
+	like the termcap default of 65.
+	2. Added an if(deftask("mtclean")) to prevent mtclean from being
+	called if it isn't defined, i.e., when running irafo=v2.9.
+	3. Moved the cl<loginuser.cl to after the user package task
+	definitions, to allow the user to override these definitions in
+	their loginuser.cl file.  (6/20)
+
+pkg/plot/t_pradprof.x
+        The new pradprof task was using the file name template expansion

+	producing an error if the input image name was an image section.
+	(6/23/92, Davis)

+
+pkg/images/filters/t_gauss.x
+	An incorrect convolution kernel was being computed in the case

+	Added benhur (Ron Probst's Sun) to the hosts files on tucana, orion,
+	gemini, and ursa - this is not a new machine but it must have slipped
+	through the crack during the v2.10 upgrade.  (7/24 jvb)
+
+--------------------------------
+IRAF V2.10.1 (patch-1) released.  Tucana system version number incremented to
+V2.10.2 (7/24)
+
+lib/finfo.h
+	1. This file contained a series of defines FI_[RW]OWNER etc. giving
+	the bit *number* (1, 2, 3, etc.) for the file permissions bitflags.
+	Bitflags are preferable and more conventional so I added a parallel
+	set of statements FF_[RW]OWNER, FF_[RW]GROUP, etc., defining the
+	bitflags.
+
+	2. Two new file permissions flags FF_RDLOCK and FF_WRLOCK were added.
+	These are normally zero (as before) but can be set by the zfinfo
+	kernel routine to indicate that a temporary read or write lock is in
+	place on the file.  (7/24)
+
+sys/fio/fwtacc.x
+	The routine had a number of problems.  It was rewritten to use the
+	new FF_{RD|WR}LOCK flags returned by zfinfo to determine whether a
+	temporary lock is preventing access to a file.  The "wait for
+	access" will occur only if "filewait" is enabled in the environment
+	and a temporary lock is in place on the file.  This should fix the
+	bogus "waiting for access to file" messages we have been seeing
+	occasionally.  (7/24)
+
+sys/gty/gtyopen.x
+sys/tty/ttyopen.x
+	The code which scans along looking for the `:' character when
+	expanding ":tc=device:" fields could run off the end of the string
+	if the : character was missing.  Added checks for beginning of
+	string and EOS.  (7/28)
+
+pkg/images/imfit/t_imsurfit.x
+        Fixed a bug in the section reading code. Imsurfit is supposed to switch
+        the order of the section delimiters in x and y if x2 < x1 or y2 < 1.
+        Unfortunately the y test in the code was if (y2 < x1) instead of 
+        if (y2 < y1). Whether or not the code actually works correctly
+        depends on the value of x1 relative to x2. This bug was not present
+        in 2.9.1 but is present in subsequent releases. (7/30 LED)
+
+mkpkg
+noao/mkpkg
+	Added a means to set the spoolfile name to the "mkpkg summary"
+	function of the package root mkpkg file.  One can now generate the
+	summary with a command such as
+
+	    mkpkg summary spool=filename
+
+	to cause the sumary to be generated from file "filename".  (8/03)

+	1. There was a (normally) harmless bug here in that the real and
+	double versions of the ieenan common had the same name, i.e. were
+	shared.  There are now separate ieenanr, ieenand commons.
+
+	2. The code which detects a NaN uses the technique of equivalencing
+	an integer array of length  1 (real) or 2 (double) to the floating
+	value so that a bitmask can be used to check for the NaN exponent
+	(here NaN actually means any non-finite IEEE value).  On most systems
+	the exponent for a double will be in the first integer of the 2
+	element array, but on a 386i (Intel) the second longword is used.
+	The code was modified to parameterize this offset and flag it as
+	machine dependent.  (8/15)
+
+unix/hlib/mkpkg.sf.I386
+	1. Added entries for the i386 versions of ieeer.x, ieeed.x.
+	2. Set up mwcs$wftan.x to be compiled with no optimization.  The
+	optimized version of this routine returns a garbage value for the
+	declination (it calculates it correctly but the code which outputs
+	the value to the w[] output array is incorrect).  (8/16)
+
+pkg/cl/pfiles.c
+	When pfileload is called to load the parmeters for a pset task the
+	parameter file name assigned to the pset can come from the pset
+	parameter of a running task which uses the pset.  Hence, pfileload
+	scans the task descriptors on the task to see if any reference the
+	pset.  The "newtask" pointer, set during task startup, was being
+	used to start the scan of the control stack containing the task
+	descriptors.  This could fail in some circumstances as newtask is an
+	invalid pointer except when a new task is being initialized.  (8/17)
+
+	This problem was an interesting case study in debugging techniques.
+	I at first tried to use dbx on this problem; this is normally
+	desirable with CL problems due to the lengthy procedures common in C
+	code.  This was on the Sun 386i where the problem was seen.  I had a
+	lot of trouble getting dbx on the 386i to use the source files, even
+	though the files were compiled -g.  Eventually it became clear that
+	dbx will not permit source code debugging on the 386 if the iraf
+	shared image is used (there is no such problem on the other Suns).
+	Source code debugging would work if the process was linked -z.  Of
+	course, then the problem went way.  The 386i is very slow so by the
+	time I determined that I was wasting my time I had wasted 2 hours.
+	Looking at the problem with adb, I found the problem within 20
+	minutes.

+pkg/images/filters/fmedian.x

+pkg/images/filters/fmd_maxmin.x
+	The fmedian task could crash with a segmentation violation if image
+	pixel to integer mapping was turned off (hmin = zmin and hmax = zmax)
+	and the input image contained data outside the range defined by zmin
+	and zmax. Added calls to amink and amaxk for integer images and a
+	call to amapr for floating point data to protect against out of bounds
+	data. (8/18/92, Davis)
+
+sys/imio/iki/qpf/qpfwattr.x
+	Modified to return INDEF as the value of the integral over an
+	attribute range list, if no range list is defined or either or both
+	ends of the range are open.  (8/18)
+
+sys/mwcs/mwsaveim.x
+	The expression "if (ndim == 1 || (ndim == 2 && ...))" was incorrect
+	as the ndim==2 case contained references to CD matrix elements that
+	might not contain valid floating point values in the case of a 1 dim
+	wcs.  (8/18)
+
+pkg/images/imutil/imcopy.x
+	Added a call to flush after the verbose status output so the the
+	output will appear immediately on the terminal. (8/19 LED)
+
+unix/os/zxwhen.c
+	Added some #ifdef i386 code to reenable the floating point exceptions
+	following such an exception.  On the other Sun systems this is
+	automatic, but on the 386i it has to be done explicitly.  (8/20)
+
+	Note 8/21 - the above fix works fine under the debugger, but there
+	are still problems trapping repeated floating exceptions when a
+	386i process executes normally.  There are no such problems on any
+	of the other Suns (the interface is the same) so this tends to
+	indicate a problem with the 386i.
+
+dev/termcap
+dev/graphcap
+	Added entries for Kermit terminal emulator supplied by Pat Seitzer.  
+	The termcap entry is for MS Kermit 3.0 in VT320 mode; graphcap for 
+	Kermit3.10 and CGA or VGA display.		(8/20 ShJ)
+
+unix/os/zfiomt.c
+	1. The "ue" option (update-eot, or force search for EOT) was not
+	working correctly - it had never been used until recently.
+	2. The "ow" option (overwrite EOF) was tested and optimized.  (8/20)
+
+sys/fmtio/dtcscl.x
+	This routine scales a double floating value to determine its mantissa
+	and exponent when printing the number.  For numbers smaller than .1
+	this is done as follows:
+
+	    while (v < 0.1d0) {
+		v = v * 10.0d0
+		e = e - 1
+	
+	The problem with this seemingly simple piece of code is that if V is
+	an IEEE subnormal value and IEEE underflow-to-zero is enabled, any
+	arithmetic operation on V will return a zero.  Hence, even though
+	V is nonzero to start with, V * 10 returns zero.  If V underflows to
+	zero the code segment above will enter an infinite loop.  To fix
+	this a test for v==0 was added to the loop to check for underflow.
+
+	On machines which have good hardware support for IEEE floating
+	computations involving subnormals the best thing to do is to NOT
+	underflow to zero, but rather to retain the subnormal values.  This
+	increases the precision of floating point computations in small
+	number arithmetic.  On some systems however, underflow (or inexact)
+	requires a trap and recomputation in a trap handler to produce the
+	correct IEEE result, and this can be very inefficient.
+
+	As an example, In the case of Sun/IRAF we currently have underflow
+	to zero enabled due to the expense of recomputation for the ffpa and
+	some early sparc systems.  Suns with these processors will silently
+	underflow to zero.  Some other Sun systems do not employ
+	recomputation of subnormals and these systems ignore the request to
+	underflow to zero, returning a valid IEEE subnormal instead.  This
+	includes the 386i and some sparc based systems (different sparc
+	systems have different floating point units).  Hence, the behavior
+	of systems even within the Sun product line will vary in the way
+	subnormals are treated.
+
+	(A subnormal is a number smaller than about 1.175e-38 for real and
+	2.225e-308 for double).  (8/21)
+
+sys/gio/fpnormd.x
+sys/gio/fpnormr.x
+	These routines (called by fp_equal[rd]) scale floating point numbers
+	in a way similar to dtcscl.x, above.  In principle they could be
+	subject to the same problem with underflow to zero and infinite loops,
+	so I added a check for underflow to these routines as well.  (8/21)
+
+unix/os/zfioks.c
+	1. Fixed a byte swap bug in the server side code that was preventing
+	it from constructing the network address properly to call back the
+	client.  This affected only the "little-endian" machines, such as
+	the decstation and 386i.
+	2. Changed the default value of MAXCONN from 0 to 1, since that is
+	probably what it should be anyway (I think I got the 0 out of someone
+	else's code).  (8/21)

+
+unix/os/tape.c
+	1. Increased the maximum i/o buffer size to 262144 and changed the
+	default read request size to 64512.
+	2. Added a "seek" command, for testing i/o to devices that respond
+	to a seek request.  "seek" to report the current offset, seek nnn[bkm]"
+	to seek to the given block, kilobyte offset, or megabyte offset.
+	The block size is whatever was used in the last read request, or
+	64512 at program entry.  (9/07)
+
+sys/osb/zzeps2.f
+	Added an alternate version of the machine epsilon computation program
+	which may avoid problems seen on some systems with excess precision
+	due to the epsilon value being accumulated in a register.  (9/10)
+
+sys/imio/imaccess.x
+	Was failing to strip off the ksection before calling iki_access.

+sys/osb/strupk.c
+	This routine was calling the C strlen(), which was an inadvertent
+	interface violation (VOS code bypassing the kernel and using host
+	facilities.  This caused a link failure on VMS/IRAF, after the
+	str routines in the VMS/IRAF kernel were renamed to avoid name
+	collisions with host library routines (hence strlen was no longer
+	in libos.a).  The routine was rewritten to use a for loop instead

+	The weighting was changed from using the square root of the exposure

+
+dev/hosts
+	Modified a number of these hosts files on different CCS Suns and
+	IRAF development systems to establish and check IRAF networking
+	to/from felis.  (10/5 jb)
+
+unix/os/zfioks.c
+	A new connect protocol has been added to iraf networking called
+	rexec-callback.  This is a variation on the rexec protocol.  Rexec
+	is used to start up the remote kernel server as before, but instead
+	of communicating via the rexec stdio stream to the remote process,
+	the server calls the client back on a private socket set up by the
+	client.  This ensures a direct socket connection, which is not
+	always guaranteed when using the rexec stdio streams.  For example
+	when using rexec to start up a kernel server on a VMS host running
+	Multinet, the stdio streams are routed through a VMS mailbox on the
+	VMS side.  This fails due to lost data resulting from the mailbox
+	being too small, and would be inefficient even if it worked.
+
+	The rexec-callback connect protocol is enabled in the .irafhosts file
+	entry for a node (since this is where protocol selection currently
+	occurs for rexec vs. rsh).  To enable the rexec-callback protocol,
+	one adds the string "rexec-callback" after the password field for a
+	node, e.g.,
+
+		robur		: <username> <password> rexec-callback
+
+	A number of related changes were made to the VMS/IRAF networking
+	driver, which is new for V2.10.  These are documented in the VMS/IRAF
+	upgrade notes file.  (10/06)
+
+	[NOTE - the way the rexec-connect protocol is enabled was changed;
+	see the entry for zfioks below.  10/11]
+
+sys/mtio/mtlocknam.x
+	The magtape lock file name is now constructed as "node!tmp$mtxx.lok"
+	rather than "tmp$mtxx_node.lok", causing the lock file to be
+	maintained on the same node as the drive itself.  (10/07)
+
+sys/ki/kienvreset.x
+	This routine is called to propagate runtime changes of environment
+	variables to remote iraf kernel servers.  It was passing all
+	variables, but was modified to filter out redefinitions of the
+	host-specific variables "iraf", "host", and "tmp".  This is necessary
+	as these variables may have different values on different hosts.
+	It is also needed to be consistent with kiopenks.x.  (10/07)
+
+unix/boot/bootlib/tape.c
+unix/boot/rtar/rtar.hlp
+unix/boot/wtar/wtar.hlp
+	Replaced RTAR and WTAR by new versions updated for V2.10 magtape
+	i/o.  The old versions read the dev$devices file to map iraf device
+	names like "mta" to the corresponding host device names.  In V2.10
+	the tapecap file replaces the devices file, and the tapecap file
+	format is too complex to be worth parsing in a HSI utility, so in
+	V2.10 host magtape device names such as "/dev/nrmt8", "MSA0" etc.
+	must be used with RTAR and WTAR.  The VMS/IRAF versions of these
+	utilities now restore file dates properly, provided the VMS logical
+	name IRAFGMTOFF is defined correctly (see the VMS notes file for the
+	details).  (10/10)
+
+sys/ki/ki.h
+sys/ki/kiconnect.x
+	The dev$hosts file now supports two types of host entries, "connect"
+	entries and "route" entries.  A connect entry is what we have always
+	had, e.g.
+
+	    ursa u	: ursa!/iraf/iraf/bin.sparc/irafks.e
+
+	A route entry is an entry such as that for node "draco" below:
+
+	    robur	: robur!irafks
+	    draco	: @robur!draco
+
+	another use is for logical node names, e.g.,
+
+	    lpnode	: @ursa
+
+	A route entry is denoted by the character `@' as the first character
+	in the server command field.  In a reference to a network object
+	such as "node!foo", if node is defined as "@bar", the string "node"
+	is replaced by "bar", i.e., by whatever follows the @, after which
+	the network object name is rescanned.  For example, given the
+	definitions for node robur and draco above, "draco!foo" and
+	"robur!draco!foo" are equivalent references.  IRAF networking will
+	automatically map the former reference to the latter internally.
+
+	This facility provides a simple static routing capability for IRAF
+	networking, allowing connects to specific nodes to be routed through
+	another node.  This can be used, for example, to use a certain node
+	as a gateway between different types of networks, such as tcp/ip and
+	decnet.  (10/11)
+
+unix/os/zfioks.c
+	A number of features were added to the unix/iraf network driver.
+
+	    o	The connect protocol may now be specified in the hosts
+		file entry for a node.  For example,
+
+		    robur	: -rcb robur!irafks
+
+		causes the rexec-callback connect protocol to be used to
+		connect to node robur.  The possible protocols are -rsh
+		(rsh), -rex (rexec) and -rcb (rexec-callback), with the
+		default being -rsh.  (The "irafks" in the above example
+		is a VMS symbol defined in the VMS/IRAF irafuser.com file,
+		used to start the kernel server on a VMS node).
+
+	    o	A new argument "-log <file>" is now supported on the irafks
+		command line.  Since the irafks command line is taken from
+		the dev$hosts file in a normal client connect, the hosts
+		file can be edited to turn on zfioks level debug logging.
+		For example,
+
+		    tucana t	: -log ks.out tucana!/usr/iraf/bin.sparc/...
+
+		Any file can be specified, for example /dev/tty.  If the
+		-log argument is given before the node!cmd as in the example
+		above, logging is enabled on the local node.  If the -log
+		argument follows the node!cmd, it is processed by the kernel
+		server on the remote node and enables logging on that node.
+
+		This is related to irafks level logging.  irafks level
+		logging is a feature that irafks has supported for some
+		time.  It is enabled by including "-d <file>" on the irafks
+		command line.
+
+	    o	The networking daemon for the in.irafksd daemon may now be
+		started manually (normally it is started via a rsh command
+		from a client during a rsh connect).  For example,
+
+		    irafks.e in.irafksd <port> <auth> [timeout]
+
+		would start the daemon on the specified port.  Clients would
+		have to specify the given auth code to connect to the port.
+		The daemon executes with the UID of the calling process.
+		Care should be taken to avoid security problems, e.g., this
+		should be used only with "safe" accounts.  Currently,
+		commands such as sps, ps, etc. will show the full command
+		line including the auth code so there is little security.
+
+		When the daemon is started in this way the irafks.e will
+		exit immediately, leaving the daemon running as a forked
+		process.  The daemon runs forever until killed, unless a
+		timeout is specified.
+
+	    o	Arguments such as "rexec-callback" are no longer supported
+		in the .irafhoss file.  Instead, this scheme has been
+		generalized to permit any network parameter to be overridden
+		for a particular node in the user's .iraf hosts file.
+		The parameters that can be set are "port", "auth", "hiport",
+		"timeout", and "protocol".  These are all numeric parameters
+		except "protocol" which should be specified as "rsh", "rex",
+		or "rcb".  For example,
+
+		    corvus	: none none port=20000 auth=12345
+
+		would cause connects to node corvus to be directed to
+		socket 20000 using the auth code 12345.  The login name
+		and password are not used when connecting to a running
+		daemon, so they are given as "none" in the example.
+
+	These changes should be backwards compatible with the V2.10.1
+	version of IRAF networking.
+
+	In case it isn't obvious, the above changes combined with the
+	enhancements to VMS/IRAF networking support (tcp/ip servers, runtime
+	selection of either tcp/ip or decnet transport) allow connections to
+	be made transparently to any VMS node running decnet, using a node
+	running both tcp/ip and decnet (e.g. a VMS node running Multinet) as
+	a gateway between SPAN and the Internet.  For example, "type
+	draco!login.com", where draco is a decnet node, given the hosts file
+	configuration showed in the examples, would result in 1) "draco"
+	being replaced by "robur!draco" causing the reference to be routed
+	to node robur via rexec-connect, 2) robur passes the request to node
+	draco via decnet.  This requires a .irafhosts file on the gateway
+	node (robur) since there is no way to respond to a password prompt
+	from a kernel server running as a network process on a remote node.
+	(10/11)
+
+unix/os/zmain.c
+	Problems were encountered passing irafks commands such as -log or
+	-rcmd to the irafks task when called as a standalone host process.
+	This was because the IRAF zmain for unix/iraf was intercepting all
+	`-' prefixed command arguments.  The zmain was changed to filter out
+	only those arguments it uses, e.g., -c, -C, -d <file>, and -w.  For
+	completeness a new flag -h (host process) was added.  This is the
+	same as calling the process with no arguments, i.e., it is the
+	default.  Unknown flags will no longer cause a usage message to be
+	printed, instead they are just passed on to the iraf task.  (10/11)
+
+pkg/cl/builtin.c
+	The internal name clscan(), used to implement the CL scan() function,
+	was changed to clscans() to avoid a name clash with the FMTIO routine
+	clscan.  This only happens on systems where Fortran and C externals
+	share the same name space, and shared libraries are used.  (10/12)
+
+pkg/system/references.cl
+	Changed a couple of "uniq"s to "unique", which is the full name of
+	the LISTS task used in the script.  (10/12)
+
+pkg/cl/grammar.y
+	The CL grammar was changed to give a higher precedence to the
+	exponentiation operator than to unary minus.  The former precedence
+	was inconsistent with the Fortran expression syntax that the CL
+	is supposed to emulate.  (10/12)
+
+sys/ki/kbzstt.x
+	This routine was calling zsttks (the status routine for the networking
+	driver) with a fixed channel code of zero.  This worked up until now
+	as most iraf network drivers ignore the channel code in zsttks, but
+	this is not the case with the new VMS/IRAF driver.  (10/13)
+
+dev/graphcap
+	Added entries for em4010vg (em4010 for VGA) and vwsregis (regis
+	emulator for VWS 3.3 and later).  (10/14)
+
+sys/gio/fpequalr.x
+sys/gio/fpequald.x
+	These routines could fail when comparing small numbers to zero.
+	For example, fp_equalr (1.0e-10, 0.0) would return false even though
+	the numbers are equivalent to within the machine epsilon.  This is
+	incorrect given the definition of fp_equal, even though the numbers
+	are in fact not equal.  The routine would fail because zero is a
+	special case: it cannot be normalized with fp_norm.  It was necessary
+	to add code to handle the special case of either input operand being
+	exactly zero.  (10/18)
+
+unix/os/zfiomt.c
+	1. Two new device capability switches were added.  ":ce" means
+	ignore the status of the close() system call when closing a device
+	opened read-only.  ":eo", used only in the VMS version of the
+	driver, disables writing of the double tape mark at EOT when a tape
+	opened for writing is closed.
+
+	2. The ":nf" parameter was modified to allow an integer value to be
+	given.  Without a parameter, ":nf" means rewind and space forward
+	to backspace files on a tape, e.g., because this is faster than BSF.
+	An entry such as ":nf#5" means do a BSF if the file is 5 files or
+	less back, but if more files must be skipped do a rewind and space
+	forward.  This parameter is intended mainly to help optimize file
+	seeks on slow devices like cartridge tapes.
+
+	3. The ":fc" parameter (device does a FSF on CLRO [close read-only])
+	was put in when the driver was written to accomodate some SysV systems
+	but had never been tested.  As it turns out, AIX is such a system and
+	it was necessary to make minor changes.  In particular, the OS does
+	not always do a FSF - it only does this when the file is partly read.
+	If EOF has been reached on the file (hence the tape is positioned to
+	the first record of the next file) then the FSF is skipped.
+
+	4. I added a couple of zmtdbg calls during multifile skips to cause
+	the file number to be updated more frequently, when using the status
+	output feature.  (10/18)
+
+pkg/proto/t_imcntr.x
+	Modified the imcntr task to use image templates and to check for
+	constant data. (10/27/92 LED)
+
+dev/termcap
+dev/graphcap
+	Added "lwg", an HP IIIp LaserJet on Canopus, to these files on Ursa
+	and Gemini at Frank Bull's request.  (10/27/92  MJF)
+
+dev/termcap
+dev/graphcap
+	Added entries for xgterm.  (10/27)
+
+sys/libc/cenvget.c
+	Changed envgets() to use ENVFIND rather than ENVGETS, so that the
+	routine will detect the environment variable not found condition
+	and return NULL in that case.  (10/27)
+
+sys/gio/gks/gschup.x
+	Changed the character up vector to be calculated as the nearest integer
+	instead of just being truncated to an integer.  (ShJ 10/29/92)
+
+dev/hosts
+        Added BigX to the hosts files on tucana, BigX, ursa, gemini, and
+        orion to establish IRAF networking for our new server.  (11/12 jb)
+
+dev/hosts
+        Added claret to the hosts files on tucana.  (11/13 RLS)
+
+sys/symtab/stalloc.x
+sys/symtab/stsqueeze.x
+sys/symtab/stpstr.x
+sys/symtab/symtab.h
+	The symtab package could fail with an "out of memory" error during
+	symbol table or string buffer reallocation in applications which
+	call stsqueeze to free unused storage (as when doing an stsave to
+	save to a file).  This was caused by the buffer increment being
+	increased by a factor of two during overflow, combined with stsqueeze
+	returning the unused space.  Two changes were made, either of which
+	will avoid the problem: 1) stsqueeze now reinitializes the buffer
+	increment when the buffer length is reset, and 2) the buffer increment
+	is now allowed to grow larger than a fixed value (32K) defined in
+	symtab.h.  (11/16)
+
+sys/qpoe/qpmacro.x
+	1. The code which scans a file and decodes macros was using a large, but
+	fixed size, string buffer to store the macro value.  This was
+	overflowing when extremely large time filters were stored in QPDEFS
+	as macros.  The routine was rewritten to use a dynamically reallocated
+	buffer.
+	2. The variables nodeffilt and nodefmask, which are false by default,
+	could only be set true since the "set nodeffilt" type statement does
+	not have a value and there is no unset.  For the moment, this was
+	fixed as a special case by initializing the values of these parameters
+	to the default before scanning the QPOE macro file.  (11/17)
+
+sys/qpoe/zzdebug.x
+	In the expand debug routine, used to test macro expansion, increased
+	the size of the output buffer to 128k to accomodate extremely large
+	macros.  (11/17)
+
+sys/qpoe/qpioparse.x
+	A bug which would cause "filter=..." terms in expressions to be
+	discarded was fixed.  (11/17)
+
+sys/qpoe/README
+	Added optbufsize to the list of QPDEFS parameters.  (11/17)
+
+sys/mwcs/imwcs.h
+	Increased the size of the string buffer used in the FITS read code
+	from 20480 chars to 102400 chars.  This fixed size buffer is not
+	(easily) reallocatable because the card descriptors use pointers to
+	point to the FITS card data in the buffer.  The buffer is only
+	allocated while a header is being read so the size isn't really an
+	issue.  (11/17)
+
+sys/mwcs/mwsctran.x
+	The internal variable pdim, the dimensionality of the linear portion
+	of the transform, used to size the vector and matrix buffers for the
+	linear algebra, was not being computed correctly.  This could cause
+	problems when the dimension of a WCS in the transform was less than
+	the dimension of the full MWCS system.  The problem was a typo in the
+	statement
+
+		pdim = min (WCS_NDIM(w1), WCS_NDIM(w1))
+
+	the second w1 was changed to w2.  (11/17)

+
+sys/imio/iki/qpf/qpfwfilter.x
+	The QPF interface uses a sequence of QPFILTxx cards to record in the
+	image header the QPOE filter used to generate an image.  To avoid
+	overfilling the header, excessively long filter strings are truncated.
+	The truncation limit was increased from 1024 chars to 4096, increasing
+	the number of output cards from a maximum of 16 to 64.  In addition,
+	if truncation occurs the string "..." is now written to the end of the
+	last card to indicate that the filter string has been truncated. (11/20)

+
+pkg/cl/unop.c
+	On some systems (sparc) CL expressions such as -(big-floating) would

+	Modified to use the TCSETAW ioctl instead of TCSETAF in some cases
+	(SysV systems only).  (1/15)
+
+pkg/dataio/reblock/t_reblock.x
+pkg/dataio/doc/reblock.hlp
+	Added support for multiple disk file input and output to the reblock
+	task. (1/20/93 LED)
+
+dev/hosts
+        Added Daryl Willmarth's machine "jannu" on Tucana.
+	(1/20 FV)
+
+dev/hosts
+	At Ed Anderson's request, added nodes anasazi and prometheus to
+	dev$hosts on tucana, ursa and gemini.  The lacerta pathname was 
+	updated in these files as well.			(1/21/93 ShJ)
+
+dev/termcap
+dev/graphcap
+	Cleaned up the VMS specific entries for lw6-10 so all are available
+	now from VMS/IRAF.  Graphcap needed a vapl6 entry; termcap needed
+	entries for vapple[6,8-10].			(1/20/93 ShJ)
+
+dev/devices.hlp
+	Updated the first section of this file to have accurate locations for
+	the various printers and to include the device names for generating 
+	PostScript output files. 			(1/21/93 ShJ)
+
+pkg/images/filters/fmedian.x
+	The fmedian task was printing a lot of garbage debugging information
+	under iraf 2.10.2. Removed the eprintf statements. (1/25/93 LED)
+
+pkg/system/phelp.cl
+	Changed the default value for the parameter "all" to "yes".  This
+	causes phelp to print help for all modules matching the given
+	template, rather than just the first one.  (1/26)
+
+pkg/system/doc/help.hlp
+	Added a description of the "all" parameter.  (1/26)
+
+sys/etc/xerstmt.x
+	The code which modifies the `error (ddd, "message")' command sent to
+	the CL when a task aborts was modified to eliminate characters such
+	as newline or double quote which could cause the syntax of the
+	generated command to be invalid.  (There are 31 cases of "call error"
+	statements in the core distribution which contain unwanted newline
+	characters in the message string).  (1/27)
+
+pkg/images/tv/wcslab/wcslab.x
+        Fixed a bug in the axis mapping code in wcslab which was causing the
+	task to fail in some circumstances if the input image was a section 
+	of a higher dimensioned parent image. (1/28/93, Davis)
+
+vms/gdev/sgidev/sgi2veps.for +
+vms/gdev/sgidev/mkpkg.com
+vms/hlib/sgiqueue.com
+dev/graphcap
+	Added an SGI translator for Encapsulated PostScript to VMS/IRAF.
+	As with the Unix version of the translator, the device names are
+	eps, epsl and epsh.  The output file is named sgixxxxx.eps and
+	is left in the users home$ directory.	(2/1/93 ShJ)
+
+unix/hlib/install
+	Added a number of statements such as "rm -f $TEMP >& /dev/null" to
+	ensure that any existing temp files are deleted before trying to
+	create new ones (file creation can fail due to permissions problems).
+	(2/01)
+
+vms/gdev/sgidev/sgi2vapl.for
+	Modified to close the output file before sending it to the printer
+	queue with sndjbcw.  Without this, the file wouldn't be closed until
+	the program finished, possibily resulting in an intermittent error:
+	%RMS-E-FLK, file currently locked by another user.  This was more
+	likely to be seen on a [relatively] fast machine such as Robur, when
+	the queue processing could turn on before the translator completed.
+	In this case, the output file would still be open [and locked] by the
+	executing sgi2vapl program.		(2/2/93 ShJ)
+
+dev/hosts
+        Modified this file on all hosts for Fred Gillett's new Sun called
+        turkey.  (2/2/93 jb)
+
+dev/hosts
+	Added the GONG machines soi and mdi to hosts files on tucana, orion
+	and ursa.  Added on gemini by Nigel.  (2/2/93 MJF)
+
+pkg/images/tv/wcslab/wcslab.h
+pkg/images/tv/wcslab/wcs_desc.h
+pkg/images/tv/wcslab/wcslab.x
+pkg/images/tv/wcslab/wlwcslab.x
+        Removed a dependency on the file gio.h from the wcslab task.
+	(2/11/93 LED)
+
+pkg/images/imutil/t_imslice.x
+	Removed an error check in imslice, that was preventing the task from
+	being used to reduce the dimensionality of images where
+	IM_LEN(im,slice_dimension) = 1.
+	(2/16/93 LED)
+
+dev/imtoolrc
+dev/graphcap
+	Added a new frame buffer, imt37, at Skip Schaller's request for
+	the Loral 1200x800 CCDs. (2/17/93 MJF)  Modified imt37 and imt26
+	(cryocam) to suit KPNO nomenclature.  (2/18/93 RLS)
+
+pkg/images/tv/imexamine/ierimexam.x
+pkg/images/tv/doc/imexamine.hlp
+	The simple gaussian fitting was inadequate and gave biased answers.
+	Replaced this algorithm with NLFIT version.  It is still just a two
+	parameter fit with the center and sky being determined and then fixed
+	as before.  (3/2/93, Valdes)
+
+dev/hosts
+        Merged all differences on ursa, gemini, orion, and bigx back into
+        tucana's hosts file.  (3/5/93 jb)
+
+pkg/images/tv/imexamine/iestatistics.x
+	The statistics computation was done in real precision, using aavgr,
+	which gives an incorrect standard deviation, presumable because of
+	precision truncation, when the mean is large and the actual data
+	noise is small.  The routine was changed to use the double
+	precision version, aavgd, which gives the correct results.
+	(3/10/93, Valdes)
+
+noao/mkpkg
+	Added support for HPUX.  (3/14)
+
+pkg/cl/main.c
+	Modified memneed(), used to allocate space at the end of the
+	dictionary, to quad align the allocated storage.  (3/14)
+
+pkg/cl/pfiles.c
+	Modified this code to remove an assumption about the amount of
+	space allocated by memneed.  (3/14)
+
+sys/imfort/tasks/mkpkg		-
+sys/imfort/tasks/README
+	Deleted the mkpkg, which is system dependent.  (3/14)
+
+unix/os/alloc.c
+	Modified alloc to allow the drive in it unallocated state to be
+	owned by any system uid (any uid < 10), rather than insisting that
+	the drive be owned by root.  If the drive is owned by any system
+	uid and has world rw permission it can be allocated under this
+	new scheme.  This avoids requiring that the system manager set
+	the device ownership to root on systems where the device is owned
+	by bin or some other system uid.  (3/15)
+
+mkpkg
+	Added irix and hpux support.  (3/15)
+
+dev/hosts
+	Added otter to hosts file on tucana, ursa, gemini, orion, and 
+	bigx.  (3/24 jb)
+
+dev/graphcap
+dev/termcap
+	Added entries for lw15|lwcloset to tucana, ursa, gemini, orion, and
+	bigX.  (3/26 ShJ)
+
+sys/libc/cread.c
+	The case of EOF on a text file was not being handled correctly.  (3/31)
+
+sys/fio/ffilsz.x
+	The file size was not being computed correctly in the case of a file
+	opened for writing and positioned to EOF, with some unwritten data
+	in the file buffer.  (4/05)
+
+pkg/cl/exec.c
+	The LT_STDINB, LT_STDOUTB flags were not being propagated into the
+	task descriptor correctly (they were being treated as additional
+	cases of mutually exclusive task types).  (4/07)
+
+pkg/images/doc/gauss.hlp
+	Fixed two sign error in the equations in the documentation for
+	the gauss task. (4/13 LED)
+
+unix/hlib/libc/stdio.h
+	Added a declaration for gets().  (4/16)
+
+pkg/images/imarith/imcombine.gx
+	There was no error checking when writing to the output image.  If
+	an error occurred (the example being when an imaccessible imdir was
+	set) obscure messages would result.  Errchks were added.
+	(4/16/93, Valdes)
+
+pkg/images/doc/rotate.hlp
+	Fixed a bug in the rotate task help page which implied that automatic
+	image size computation would occur if ncols or nlines were set to 0
+	instead of ncols and nlines.  (4/17/93, LED)
+
+sys/imio/iki/stf/stfrgpb.x
+	This code was directly referencing fields of the GPB in calls to
+	imaddX routines to build the image header.  Since fields in STF
+	group parameter blocks are often not aligned, this could fail for
+	type double on machines that require that double values be double
+	aligned.  The code was modified to copy the values out to
+	temporary variables (which the compiler will automatically align),
+	passing the aligned temporary values in the imaddX calls.  (5/04)
+
+dev/graphcap
+	Merged in latest xgterm entries (these are not compatible with
+	early prerelease versions).  (5/05)

+	The changes should be backwards compatible; any compatibility

+
+pkg/images/geometry/t_imshift.x
+	Added support for type ushort images to the imshift task in the
+	case that the pixel shifts are integral not fractional.
+	(5/8/93 Davis)
+
+pkg/images/imarith/icmedian.gx
+	The median calculation is now done so that the original input data
+	is not lost.  This slightly greater inefficiency is required so that
+	an output sigma image may be computed if desired.  (5/10/93, Valdes)
+
+images/doc/imshift.hlp
+	Fixed a typo in the name of the "interp_type" param. (5/13/92 MJF)

+	Fixed a bug in the way the phistogram task was reading in data
+	redirected from the standard input. (5/20 LED)
+
+/dev/hosts
+	Added lemming to all hosts files. (5/25 jb)
+
+images/imarith/icgdata.gx
+	There was an indexing error in setting up the ID array when using
+	the grow option.  This caused the CRREJECT/CCDCLIP algorithm to
+	fail with a floating divide by zero error when there were non-zero
+	shifts.  (5/26/93, Valdes)
+
+sys/ki/kixnode.x
+	This routine used a fixed length intermediate buffer which could
+	result in truncation of a resource name.  Modified to base the buffer
+	size on the size of the resource string being edited.  (5/29)

+dev/hosts
+	Added odysseus to tucana/orion.  Nigel added it to ursa/gemini.
+	(6/15MF)
+
+sys/vops/arav.gx
+	Changed the termination condition to cause loop termination if an
+	interation results in fewer pixels being rejected.  This shouldn't
+	happen, but is possible due to arithmetic errors when the algorithm
+	is near convergence.  (6/19)
+
+sys/imio/iki/oif/oifopix.x
+	Improved the error handling for the case where there is no pixel
+	storage file.  (6/21)
+
+gio/ncarutil/conbd.f
+gio/ncarutil/conrec.f
+	Dimension of array IR in subroutine STLINE was increased from 20k 
+	to 80k.  This array, in common block CONRE2, holds the starting
+	location of all contours at a given level.  Larger data arrays, and 
+	users wanting to contour each pixel rather than subsampling or block 
+	averaging, have necessitated the gradual increase of this array 
+	over the years from its original value of 500 to 80000.  (ShJ 6/21)
+
+pkg/plot/phistogram.x
+	Fixed a bug in the way phistogram was binning real data read in from
+	a list or image that was causing to create one less bin than required
+	to hold the data. (26/6/93, Davis)
+
+dev/hosts
+        Added sandalwood to all hosts files, ie tucana, bigx, ursa, gemini,
+        and orion.  (jb 7/1/93)

+doc/vmsiraf.ms		+
+doc/vmsiraf.ms.v29	+
+	Installed the new, extensively revised VMS/IRAF manual.  (7/01)
+
+unix/hlib/buglog.csh
+	Modified to also append a new buglog entry to the bugs.log file in

+	A task for fitting a 2D function or "surface" to an irregularly

+
+pkg/images/geometry/geomap.par
+pkg/images/geometry/t_geomap.x
+pkg/images/geometry/geogmap.x
+pkg/images/geometry/geofit.x
+	Fixed a bug in the error handling code in geomap which was producing
+	a segmentation violation on exit if the user's coordinate list
+	had fewer than 3 data points. Also improved the error messages
+	presented to the user in both interactive and non-interactive mode.
+	(7/7/93, LED)
+
+unix/os/zfmkcp.c
+	This routine makes a zero-length copy of a file, preserving the file
+	mode bits so that the application need not know about the host
+	system's view of file types, permissions, etc.  The routine was
+	modified to preserve the file mode bits EXCEPT that the new file has
+	read and write permission enabled for the owner (it is likely that
+	an IRAF application creating a new, zero length copy of a file or
+	file template will want to write to the file).   (7/07)
+
+dev/hosts
+        Added pandora.  (7/10/93 jb)
+
+sys/mwcs/mwsave.x
+	Added a missing call to sfree.  (7/13)
+
+pkg/system/doc/help.hlp
+	Deleted a comment about using device=text with the help task and

+
+pkg/images/filters/t_median.x
+pnkg/images/filters/t_mode.x

+-------------------
+V2.10.3 BETA, first release.  (7/29)
+
+mkpkg
+unix/hlib/strip.iraf
+	Minor updates to strip a few things that were being missed.  mkpkg
+	strip at the iraf root now prints some helpful messages.  (8/01)
+
+unix/hlib/login.cl
+	Added dbx and gdb to the default user package.  (8/01)
+
+pkg/images/imarith/t_imcombine.x
+	The algorithm for making sure there are enough file descriptors
+	failed to account for the need to reopen the output image header
+	for an update.  Thus when the number of input images + output
+	images + logfile was exactly 60 the task would fail.  The update
+	occurs when the output image is unmapped so the solution was to
+	close the input images first except for the first image whose
+	pointer is used in the new copy of the output image.  (8/4/93 fv)
+
+pkg/images/imfit/fit1d.x
+	When the input and output images are the same there was an typo error
+	such that the output was opened separately but then never unmapped
+	resulting in the end of the image not being updated.  Fixing the
+	typo means that only one I/O pointer is used in READ_WRITE mode
+	as intended.  (8/6/93 fv)
+
+sys/mkpkg
+sys/memdbg/			+
+lib/libmemdbg.a			+
+unix/hlib/mkpkg.sf.SUN4		+
+unix/as.sparc/zrtadr.s		+
+	Added a new system library -lmemdbg.  This is a debug version of MEMIO,
+	used to log calls to the MEMIO routines and check programs for
+	memory leaks (unfreed buffers).  See the README file in the memdbg
+	directory for details on usage.  (8/08)

+	Added a new task MEMCHK to the softools package.  This is used in
+	conjunction with the memdbg facility.  (8/08)
+
+pkg/system/sort.x
+	This very old program had some pretty small buffer sizes and hence
+	was slow sorting large files.  The buffer sizes were increased by
+	about a factor of 10.  (8/08)
+
+sys/clio/clclose.x
+sys/clio/mkpkg
+sys/etc/main.x
+	Made a minor modification to the IRAF main to close the stdio
+	streams during process shutdown.  This makes memdbg output a little
+	less confusing, although the system still allocates a number of
+	buffers that exist for the lifetime of the process and are never
+	freed.  (8/08)
+
+sys/fio/stropen.x
+	Added a call to strclose to free the file pushback buffer if any.
+	This is only necessary when pushback is used on a string buffer
+	opened as a file, as in parsers.  (8/08)
+
+sys/fio/vfnmap.x
+	Added a missing sfree.  (8/08)

+sys/vops/lz/mkpkg
+sys/vops/mkpkg
+sys/vops/vops.calls
+sys/vops/vops.men

+
+unix/boot/mkpkg/host.c
+	The routine h_direq in this file is supposed to be smart enough
+	to be able to match up directories even when symbolic links are
+	used.  It was being fooled by a case where the name of the iraf
+	root directory is not a simple "iraf" - for example on tucana the
+	root directory is currently called "iraf/iraf.develop".  When
+	h_direq fails it can cause mkpkg special file list entries to
+	be ignored.  (8/11)
+
+sys/fmtio/evvexpr.gy
+	Swapped the precedence of the unary minus and exponentiation operators
+	(the latter should have higher precedence).  (8/12)
+
+sys/fmtio/evvexpr.gy
+	1. The input arguments to the intrinsic functions INT and NINT were
+	being coerced to floating before performing the operation (harmless
+	but unnecessary, and inefficient).
+	2. The code for the intrinsic functions "short" and "long" was missing
+	and was added.  (9/04)
+
+unix/hlib/mkpkg.sf.SUN3
+unix/hlib/mkpkg.sf.SUN4
+	Added the compiler switch "-Ns2048" for fmtio$evvexpr.x.  This routine
+	(which is computer generated from evvexpr.gy and which is enormous)
+	was overflowing the Fortran compiler symbol table.  Interestingly,
+	I got the same error message and had to add exactly the same switch,
+	using the Sun Fortran compiler on the Sun and F2C on A/UX!  (9/04)
+
+dev/termcap
+dev/graphcap
+	Added HP LaserJet 4M 600dpi printer 'lw16' to graphcap/termcap file

+
+pkg/images/imarith/icscale.x
+pkg/images/doc/imcombine.hlp
+	The help indicated that user input scale or zero level factors
+	by an @file or keyword are multiplicative and additive while the

+sys/gio/gmprintf.x
+	1. gmsg (and indirectly gmsg[bcsilrdx]) was modified to format a

+	Previously it was working, but it would send any message to any

+sys/gio/stdgraph/stgopenws.x
+	When reactivating a device in certain circumstances a flag was not

+	actually being output but since the dialog box was never activated
+	they were not being printed).  (10/01)

+	The stdgraph kernel was modified to allow a message to be returned
+	as part of a cursor read.  The cursor value struct for devices such
+	as xgterm contains a field "nchars" defining the number of chars,
+	default zero, following the fixed size cursor value struct.  If this
+	data is present it is read as part of the cursor read, and played
+	in a dynamically reallocatable message buffer in the stdgraph
+	kernel.  The next stg_readtty call (as used in CL cursor reads or
+	when reading from STDIN when graphics is activated) returns data from
+	this message buffer rather than reading from the terminal.  A new
+	routine stg_msglen was added to allow the kernel to be queried to
+	see how much message data is buffered.  The message buffer is
+	emptied in each cursor read or after the first stg_readtty call.
+	(10/7)
+
+sys/gio/cursor/rcursor.x

+	If there were fewer initial pixels than specified by nkeep then the

+
+unix/as.sparc/zrtadr.s
+	MEMDBG was not returning valid values for the RETADR (return

+	Evidently the real zrtadr.s was lost back when MEMDBG was written,
+	probably due to an accidental cc -S after the package had already
+	been debugged.  The version in as.sparc was the assembler for the

+
+dev/graphcap
+gio/stdgraph/stggim.x
+	The refresh pixels function was broken due to the graphcap entry for

+	would cause an "incomplete or reentrant format" error when trying to
+	do a gim_refreshpix from an IRAF imaging application.  (2/24)
+
+gio/gim/gimrefpix.x
+	Edited the procedure header description to reflect a change in the

+
+dev/graphcap
+sys/gio/stdgraph/stggim.x
+	The name for the ME capability (refresh mapping) used in the xgterm
+	graphcap entry was a redefinition of the marker-end capability used
+	for drawing polymarkers.  Changed the name to MN.  We need a more
+	rigorous way to register device capability names to avoid this sort
+	of problem.  I usually search the graphcap file, but in this case
+	the named was used in the stdgraph kernel but was not actually defined
+	for any existing device.  (3/03)
+
+sys/imio/imwrpx.x
+	This code assumed that IM_PIXTYPE was int, the same as the type of
+	the pixel masks.  Modified to convert the pixel values if necessary
+	when writing to the output mask.  (Note that this is not necessary
+	when *reading* a mask, as IM_PIXTYPE will always be int in that 
+	case).  (3/07)
+
+sys/plio/plp2l.gx
+sys/plio/plp2r.gx
+	Modified this code to apply a max(0,value) to the input pixel values,

+	Negative input values could cause the data to be improperly encoded.
+	(3/07)
+
+pkg/math/gsurfit/gs_eval.gx
+	The sfree statement was commented out in the routines gs_evpoly
+	and dgs_evpoly. This results in over-utilization of memory and
+	occasionally in out of memory errors for tasks which make many
+	successive calls to gsvector or dgsvector if the surface type
+	is polynomial. (3/08/94 LED)

+sys/fio/mkpkg
+sys/fio/ndopen.x
+sys/fio/zzdebug.x
+	Installed a new FIO driver, the ND or network device driver.  This
+	driver can potentially support any connection oriented, streaming
+	type network or IPC communications domain.  The initial set of
+	supported communications domains are Internet sockets, UNIX domain
+	sockets, and FIFO pipes.  The type of connection is specified by
+	the "filename" argument to the driver at open time.   Both client
+	and server connections are supported.
+
+	A client or a server opens a network device connection as follows:
+
+		fd = ndopen (filename, mode)
+
+	The mode is NEW_FILE for a server, anything else for a client.
+	The file descriptor is bidirectional.  The "filename" string syntax
+	is determined by the ND driver and is transparent to IRAF system
+	and applications code.  For the UNIX/IRAF ND driver, here are some
+	examples:
+
+		inet:5177			# Internet socket, server
+		inet:5177:foo.bar.edu		# Internet socket, client
+		unix:/tmp/.IMT%d		# UNIX domain socket
+		fifo:/dev/imt1i:/dev/imt1o	# FIFO (named pipe)
+
+	Refer to the comments in fio$ndopen.x and os$zfiond.c for further
+	information.  The file fio$zzdebug.x contains sample client and
+	server tasks.  (5/01)
+
+sys/fio/zzdebug.x
+	Added two tasks "client" and "server" for testing the ND driver.
+	These also demonstrate how to do bidirectional i/o on a streaming
+	file descriptor.
+	(5/01)
+
+dev/graphcap
+unix/gdev/zfiogd.x
+	Modified the display server interface to use the ND driver.  These
+	changes allow use of socket connections to talk to the display
+	server, but are backwards compatible and will work with older
+	display server that only support fifos.
+
+	1. The "/dev/imt1" was deleted from the imtool graphcap entries and
+	replaced by the null string.  This causes the GD (not ND) driver
+	to use a default network address for the connection: the default
+	is 1) personal (per-user) unix domain socket at /tmp/.IMT<uid>,
+	2) standard imtool fifo pair at /dev/imt1[io], 3) fail.
+
+	2. The GD driver was modified to use the ND driver instead of
+	the BF driver for generic device "imtool".  The user may define
+	IMTDEV in their host environment to override the ND "pathname"
+	given in the graphcap entry for the device.
+
+	The new image display server ximtool also supports all three ND
+	protocols (tcp/ip sockets, UNIX domain sockets, fifos) and will
+	simultaneously listen for connections on all three.  Multiple
+	connections are supported, e.g. the user can be running imexamine
+	on one frame while client applications load images into 1 or more
+	other frames.  Problems can still result if multiple clients try
+	to simultaneously access the same frame buffer, or if different
+	clients have different notions of the frame buffer configuration.

+
+sys/gio/cursor/gtrctrl.x
+	Modified to set the SKIPOPEN flag on openws only for interactive
+	(inline) graphics kernels.  A F_CANCEL on the graphics spool
+	buffer in the prpsio code was cancelling the openws for a subkernel
+	and preventing it from being passed to the kernel.  The SKIPOPEN
+	is used to keep the giotr code from sending the openws again
+	when the grahics data is processed.  A better solution might be
+	to just omit the gki_write in gtrctrl but the current approch
+	appears to work.  This fixes several bugs seen recently with
+	graphics subkernels (SGI, IMD, etc.) where e.g. a gflush was
+	necessary to make a plot appear, or to keep separate plots from
+	being overplotted.  (5/07)
+
+sys/fio/putline.x
+        Putline would flush the output buffer after the last character
+        written if the number of characters written exactly filled the
+        buffer.  This was harmless in most cases, but would prevent using
+        putline to write the last character in a stropen file.  This
+        behavior was not quite correct, as FIO normally flushes the buffer
+        only when one tries to write to the next character after the end of
+        the buffer.
+
+	This bug was causing the STF image kernel to fail to read STF
+	images, due to the use of stropen in the kernel.  The bug was seen
+	only recently due to a recent fix to stropen which caused the top of
+	the buffer to be changed by one character.  The routine was changed
+	to flush only when writing beyond the end of the current buffer.

+unix/gdev/sgidev/sgi2ueps.c
+	Merged in changes from Solaris port having to do with the declaration
+	of a file descriptor as (FILE *) rather than int, added some #idefs
+	to sgi2uapl.c needed by Solaris.  Also modified the header ID string
+	produced by sgi2uapl to be "%!PS", this is required by certain HP
+	LaserJet 4M printers.		(7/8/94 MJF)
+
+pkg/utilities$t_polyfit.x
+        Revoved the dependent variable normalization which was not doing
+	anything to improve the numerical statbility of the routine and which
+	was causing problems in the computation of the reduced chi-squared
+	and standard deviation statistics.
+        (7/11/94 LED)
+
+sys/fio/zfiott.x
+	Modified the ttyio logging code to flush the output after each
+	log message.  (7/23)
+
+pkg/images/tv/wcslab/wcslab.x
+        Fixed an initialization bug in wcslab that was causing the axis labels
+        of the plot to be drawn incorrectly the first time wcslab was run. 
+        This was only a bug under 2.10.3
+        (26/7/94 Davis)
+
+pkg/images/geometry/xregister/rgxregions.x
+        The routine strncmp was being called (with a missing number of
+	characters argument) instead of strcmp. This was causing a bus error
+	under solaris but not under sun os whenever the user set the regions
+	parameter to "grid ...". (7/27/94 LED)
+
+unix/hlib/libc/kernel.h
+	Replaced this file with the version from the Solaris port, which

+
+unix/os/zfiotx.c
+unix/os/zzstrt.c
+	The terminal driver (zfioty i.e. zfiotx) has long had a weakness
+	in that it had no protection against confusion over the terminal
+	state if the terminal was accessed by two or more different file
+	descriptors.  This was the chief cause of the cursor hang problem
+	seen with xgterm occasionally.  The ehist/eparam code in the CL
+	was using two different file descriptors to set the terminal modes,
+	and when the second when in and out of raw mode it would leave the
+	first descriptor thinking the terminal was in raw mode while it was
+	not, causing the cursor to be read in "cooked" mode.  This would 
+	cause the \r (CR) delimiter in a cursor read to be mapped to \n
+	hence making it impossible to read the cursor.
+
+	The terminal driver was rewritten to maintain an internal array
+	of descriptors of open terminal devices.  When a file descriptor
+	is used to access a terminal device the driver maps the file
+	descriptor to its internal terminal device descriptor, which is
+	used to uniquely maintain state information for the device.  This
+	ensures that the device is handled consistently regardless of what
+	file descriptor is used to set the device mode.
+
+	The zzstrt code had to be modified to call ZOPNTY on each of the
+	three stdio streams, to initialize the terminal device descriptor
+	for the user terminal.  The driver looks for a special filename
+	("unix-stdin" etc.) and uses the already open stream (stdin, stdout,
+	or stderr) if one of the standard streams is specified.  (8/02)
+
+dev/graphcap
+	Changed the xgterm graphcap entry to recognize either \r or \n as
+	the trailer code for a cursor read.  This is a safeguard to permit
+	terminating a cursor read should the tty port somehow get raw mode
+	cleared, e.g. by some third party process.  (8/02)
+
+pkg/images/tv/imexamine/ierimexam.x
+	World coordinates printed in the 'r' profile graph are now formated.
+	(8/02, Valdes)
+
+unix/hlib/login.cl
+	Modified to eliminate the stty xterm case.  This causes problem when
+	TERM is set to xterm in the host environment, but the terminal is
+	an xgterm.  Now, if the user sets the terminal type to xgterm in
+	their mkiraf, this is the value which will be used.  (8/10)
+
+unix/hlib/mkiraf.csh

+unix/boot/spp/xc.c
+	Modified XC to support PKGENV values listing multiple packages.
+	Formerly XC supported multiple package environments (-p pkgenv)
+	on the command line, but permitted only a single package to be
+	given in PKGENV.  MKPKG has long supported both options.  (8/18)
+
+unix/os/zfiotx.c
+	The terminal driver had a bug affecting nonblocking raw mode
+	(IO_RAW+IO_NDELAY).  IO_NDELAY was implementing using fcntl O_NDELAY
+	on the file descriptor, which sets asynchronous mode on the
+	device with which the file descriptor is associated, i.e., the
+	tty port for a terminal device.  This will fail if some other
+	process, e.g. the unix wall/rwall task, opens and writes to the tty
+	device, clearing asynchronous mode and causing the next read of
+	the tty by the IRAF process to block.  It was necessary to modify
+	ZGETTX to handle a nonblocking raw mode read as a special case.
+	Select() is used to poll the device to see if there is any data to
+	be read, and the read is performed only if there is data to be
+	read.  (8/18)

+sys/fmtio/dtoc3.x
+	Fixed a bug that would prevent numbers from being rounded correctly
+	in special cases.  The bug affected only fixed format where the
+	number being printed was smaller than the number of decimal places.
+	For example, 0.09 printed with %.1f would be printed as 0.0 as

+sys/etc/prenvset.x
+sys/etc/prupdate.x
+	Modified prupdate to add an argument "flushout", used to force flushing
+	of the command output to the specified subprocess.  Modified prchdir
+	and prenvset to use the new calling sequence for prupdate.  prchdir
+	calls prupdate with flushout=YES, prenvset uses flushout=NO.  This
+	should fix a problem where chdir requests could be buffered and later
+	flushed after one of the referenced directories had been deleted,
+	causing the chdir sequence to fail.  (9/14)

+	When rotating about a nonzero center this code was failing to

+        Replaced a seek to EOF call with a flush call in the the tvmark task
+        "add object" procedure. On SunOS systems the seek to EOF was apparently
+        forcing the flush while on Solaris systems it was not, resulting in the

+------------
+The following changes are being merged back in following the DEC Alpha/OSF
+port.  (12/30)
+
+unix/hlib/libc/spp.h
+	Set XLONG to int (32 bits) instead of long.  This should work for
+	both 32 and 64 bit platforms.  (12/30)
+
+unix/os/zdojmp.c
+	This code assumed that jmpbuf was an int array and that a pointer
+	could be stored in the first integer element.  This fails on 64
+	bit machines where pointers are 64 bits and ints are 32.  Modified
+	to coerce the jmpbuf array to long so that both 32 and 64 bit 
+	machines will be supported.  (12/30)
+
+unix/boot/wtar/wtar.c
+	Fixed a bug in WTAR involving coercion of a pointer to an integer
+	(line 536, bp = ...).  (12/30)
+
+sys/gio/gks/gcas.x
+	Changed the procedure name from "gca" to "gcas".  There is already
+	another procedure in the same library called "gca".  "gcas" is
+	supposed to be the type short version.  (12/30)
+
+sys/gio/ncarutil/autograph/agrstr.f
+	Commented out statements number 901, 902: "no path to this statement".
+	These statements are never called as the code that calls them is also
+	commented out.  (12/29)
+
+sys/gio/ncarutil/autograph/agsave.f
+	Same thing, statement 901.  (12/29)
+
+sys/gio/ncarutil/conlib/consld.f
+	Commented out statement functions SCRTCH and IARVL.  These are never
+	called and result in a warning message.  (12/29)
+
+sys/gio/ncarutil/conrec.f
+	Commented out three lines around line 1226.  These lines were no
+	longer used because other code had been commented out, and were
+	resulting in a "Variable XX is used before it value has been
+	defined" warnings.  (12/29)
+
+sys/gio/nspp/sysint/encd.f
+	Commented out several lines that were no longer used and were causing
+	a "no path to this statement" warning.  (12/29)
+
+math/deboor/setdat2.f
+math/deboor/setdat3.f
+	This library contains three files setdat.f, setdat2.f, setdat3.f
+	all of which contain a procedure "setdat", causing library conflicts.
+	These routines are not really part of the library anyway and are
+	only used to generate data for examples in DeBoor's book, but to
+	avoid the library conflicts I changed the names of the second and
+	third procedures to setdt2, setdt3.  (12/29)

+pkg/cl/stack.c
+pkg/cl/task.c
+        The CL has long defined the dictionary and stack as arrays of
+        unsigned integer.  This causes problems on a 64 bit machine like
+        the Alpha where integer and pointer are not the same size.
+        To avoid this problem a new type "memel" was defined in a typedef
+        in config.h.  The CL code was modified as necessary to declare
+        all dictionary and stack storage and references using this new
+        type.  (12/29)
+
+pkg/cl/scan.c
+        The varargs code in this routine failed to compile on the Alpha,
+        which defines va_list as a structure rather than a variable.
+        This caused a (va_list) cast to fail.  After studying this for
+        a while I couldn't find any way to safely and portably use varargs
+        to fake an argument list as an array.  The solution adopted was
+        to just make a normal call to sscanf, putting the variable number
+        of arguments on the argument list in the normal fashion as v[0],
+        v[1], v[2], and so on.  The current implementation imposes a
+        limit of at most 32 arguments for a CL scan operation.  (12/29-30)
+
+mkpkg
+noao/mkpkg
+	Added an entry for the "alpha" architecture.  (12/29)
+
+unix/hlib/mkfloat.csh
+	1. Modified to look for .E files as well as .e files.
+	2. The script was failing because tar -tf would output file names
+	with a trailing space after the filename (surely a bug in OSF1 tar).
+	Had to add a filter to trim the whitespace.
+	3. Modified the script to treat the "generic" architecture specially,
+	avoiding any attempt to restore any binaries etc.  (12/29)
+
+sys/libc/zzdebug.c -> zztest.c
+	Renamed zzdebug.c zztest.c to avoid a name conflict with the zzdebug.x
+	in the same directory.  (12/29)
+
+unix/hlib/libc/stdio.h
+	In struct _iobuf, changed the type declarations from long and int
+	to XLONG and XINT.  (12/29)
+
+dev/hosts
+	Added an entry for "lyra" to the hosts table.  (12/29)
+
+unix/os/zopdir.c
+	1. Modified to use (conditionally) the newer versions of
+	opendir/readdir.
+	2. Testing revealed a bug in this file.  This was preventing commands
+	such as "dir /" from working on Solaris, due to a bug in the code
+	which strips trailing slashes from directory names.
+	3. zopdir would pass back a pointer coerced to an int as the "file
+	descriptor" but this would fail on 64 bit systems where pointers
+	don't fit in 32 bits.  Modified the routine to allocate a kernel
+	file descriptor for the directory and pass back a normal fd instead.
+
+	Items 1 and 2 above were actually made in the Solaris port.  (12/30)
+
+pkg/dataio/fits/t_wfits.x
+	Wfits was using the name of the @file instead of the first file  as the
+        root output fits file name if the number of output files was 1.
+        (1/18/94 LED)
+
+unix/os/alloc.c

+	Added a check for the status returned by getstr() to avoid attempting
+	undefined operations on a null return value.  (1/27)
+
+sys/fio/zzdebug.x
+	Added a task "daytime" to the FIO zzdebug.  This demonstrates use
+	of the zfiond driver to connect to the TCP/IP "daytime" service to

+	Fixed a pointer addressing error found by Zarate.  (2/16 FV)
+
+pkg/plot/t_implot.x
+pkg/plot/pltwcs.x
+	When trying to plot a column of a 1D image the physical axis was
+	being set to zero and then used inapproprriately as a pointer offset
+	causing an error on the Dec Alpha port.  The axis now defaults to
+	1 and also the task now beeps when attempting a column plot rather
+	than plotting a point point line.  (2/16 FV)
+
+sys/imio/iki/stf/stfopix.x
+	The pointer o_im (old image header) was being used in an expression
+	even for new (non new-copy) images.  Whether or not the pointer was
+	actually referenced would depend on the Fortran compiler and how
+	it evaluated the expression.  (2/18 1995)
+
+sys/gio/cursor/grcread.x
+	A call to grc_message was missing the "stream" argument.  (2/23)
+
+pkg/system/help/helpdb.x
+	The final call to error() was missing the errcode argument. (2/23)
+
+sys/gio/gki/gkiexe.x
+	The code for GETCELLARRAY was incorrectly using zcall7 instead of
+	zcall6.  (2/23)
+
+sys/gio/stdgraph/stgreset.x
+	Not all polyline and fillarea attributes were being reset when a
+	open or close workstation (stg_reset) occurred.  Added initializations

+unix/hlib/extern.pkg
+	Installed IMCNV for use on tucana.  (3/2 MJF)
+
+pkg/images/geometry/xregister/rgxtools.x
+	Changed some incorrect amovr and amovi calls to the correct amovkr
+	and amovki calls. (3/15 LED)
+
+pkg/dataio/fits/fits_cards.x
+	Added some wfits code to filter any "END     " keywords out of the 
+	image header userarea. (3/17 LED)
+
+pkg/images/tv/doc/display.hlp
+	Clarified the explanation of the 'zrange' parameter to indicate that
+	if min/max values are defined they will be used, otherwise the image
+	is subsampled using nsample_lines to approximate the min/max when
+	determining the mapping.  (3/22  MJF)
+
+pkg/plot/t_gkixt.x
+pkg/plot/doc/gkiextract.hlp
+	Increased the size of the index array from 2048 to 8192 to accomodate
+	very large metacode files.  Added a note to the help page mentioning
+	the limit. (3/22  MJF)
+
+pkg/images/geometry/xregister/t_xregister.x
+	Added a test on the status code returned from the fitting routine to
+        prevent the xregister task from writing an output image when the user
+	quits the task in in interactive mode. (3/31/95, Davis)
+
+dev/hosts
+	Added 'vanilla' to the mountain sites on all servers.  (4/5/95  MJF)

+
+sys/gio/imdkern/t_imdkern.x
+	The IMD kernel was modified to add a new debug option that will
+	work even when the kernel is run as a generic subkernel of the CL.
+	For example if we do a "set idkdebug = /tmp/idk.out" then the
+	kernel will log GKI input to the file ikd.out.  In debug mode output
+	is flushed after every output line, hence one can do a "tail -f" on
+	the file to monitor the kernel during execution, to see what the
+	CL is sending it.  Currently this feature is only available in the
+	IMD kernel but it would be easy to add it to other graphics kernels 
+	if needed.  (4/13)
+
+sys/etc/prpsio.x
+	The pseudofile i/o controller was modified to fix what has been
+	referred to as the "imdkern bug", where the IMD kernel would not
+	flush its output to the image display as it used to prior to 2.10.3.
+
+	What happened was that the addition of GUI support in 2.10.3
+	included support for bidirectional GIO, where the application sends
+	a request to the graphics server and reads back the response.  The
+	pseudofile i/o system buffers messages in the graphics streams in
+	the CL and in order to support bidirectional transfers it is
+	necessary to cancel the i/o buffer for the graphics stream to
+	prepare for a possible response.  No bug was found in this code, but
+	what was happening was that when a control message was sent to
+	PSIOCTRL a request such as close-workstation would write the GKI
+	request to the graphics stream; this stream is just a file buffer in
+	the CL and any data written there is not passed to the graphics
+	subkernel until the subkernel reads from its input stream.  In most
+	circumstances subsequent graphics output would cause the buffered
+	control request to be passed on to the subkernel and this is what
+	was happening in versions of IRAF prior to 2.10.3.  The addition of
+	the cancel-stream statements in 2.10.3 would cause these buffered
+	control requests to be discarded.  In the case of imdkern the kernel
+	would never see the close-workstation request, and the output would
+	not be flushed until an event occurred such as shutting down the
+	kernel with gflush.
+
+	The fix was to modify the PSIOCTRL handling in prpsio.x to push an
+	XMIT request on the psio control stack, to cause the buffered
+	control requests to be passed on to the subkernel in the next
+	iteration of the pseudofile i/o controller.  (4/13)

+	KI was modified to change the way logical node names are handled.
+	A logical node name is an environment variable which maps to a
+	node name from the dev$hosts table.  Logical node names are used
+	to create symbolic links to physical node names, providing physical
+	node name independence, or to otherwise alias node names without
+	having to modify the hosts table.
+
+	The initial implementation of this feature was dangerous as logical
+	node names and other environment variables share the same name
+	space and inadvertent name collisions could occur.  The fix was to
+	require a special syntax to define a logical node name: an environment
+	variable is treated as a logical node name only if the node delimiter
+	character "!" is appended to the value string.  For example, "set
+	alpha = foo.bar.edu!" would define logical node alpha to be the same
+	as foo.bar.edu.  (4/13)
+
+unix/hlib/motd
+	Version number incremented to V2.10.4BETA.  (4/13)
+
+sys/fmtio/evvexpr.gy
+	This routine was modified as follows to fix bugs seen in IMEXPR.
+	1. There was a bug affecting binary scalar/vector boolean operations
+	where the vector operand was the second operand: the type conversion
+	would fail if the vector operand was of type boolean.  The routine
+	xvv_boolop was modified to treat any input boolean operands as
+	integer (they are stored in expressions operands as integers anyway),
+	this avoids the special case and is a bit more general.  The test
+	case used was the expression "(J <= 5 && I <= 10) ? 0 : a".
+	2. xvv_quest was modified to permit int as well as bool for the
+	input conditional.  A bug was fixed where the routine would fail
+	if the input conditional was a scalar but the data operands were
+	vectors; the code was assuming a vector conditional in this case.
+	For example, "(J <= 5) ? 0 : a" would fail, as (J <= 5) is a scalar
+	(J is a constant when evaluating the expression for a line).  (4/14)
+
+sys/gio/gascale.x
+sys/gio/grscale.x
+	These routines can modify or set a WCS but they were not setting
+	the WF_MODIFIED flag, a recent addition with the GUI support.  This
+	fixes a problem first seen with IMPLOT where cursor reads would in
+	some cases print NDC coordinates instead of pixel coordinates.  (4/15)
+
+sys/osb/miinelem.x
+	The miinelem routine was incorrectly rounding up to the next full

+	a char array of a given length.  (Bug reported by Phil Hodge May94).
+	(4/17)
+
+pkg/images/doc/fit1d.hlp

+
+sys/mwcs/mkpkg
+sys/mwcs/mwsave.x
+sys/mwcs/mwload.x
+	1. The mw_save/mw_load routines are supposed to encode a MWCS in a
+	machine independent form and later restore it, but due to a bug the
+	encoded MWCS was not fully machine independent.  mw_save uses pl_p2li
+	to compress the integer part of the MWCS descriptor, but mw_save
+	was using miipak32 to encode this for external storage.  This is
+	incorrect since pl_p2li produces a type short rather than integer
+	array.  The bug was harmless on big-endian machines like a Sun or
+	on any machine when the saved MWCS was read back on the same machine,
+	but would cause the saved MWCS to fail to load when tranferred to a
+	machine with a different architecture.  The fixed code now uses
+	mii{pak,upk}16 to transform the data.  mw_load can still read old
+	saved MWCS provided they were written on a machine of the same
+	architecture.
+	2. mw_load now initializes the axis map to a 1 to 1 mapping as in
+	a call to mw_open to create a new MWCS (formerly the axis map
+	storage was zeroed following a mw_load).  The axis map is not saved
+	and restored over a mw_save/mw_load sequence.  (4/18)
+
+sys/mwcs/zzdebug.x
+	Added two new debug tasks "save" and "load".  SAVE creates a dummy
+	MWCS, calls mw_save to encode it , and then saves it to a file
+	"mwcs.sav" in the current directory.  LOAD calls mw_load to load
+	the named MWCS save file.  Both routines call mw_show to display
+	the MWCS so that one can easily verify that it has been saved and
+	restored correctly.  (4/18)
+
+sys/mwcs/iwewcs.x
+	The routine iw_enterwcs could set the RA axis incorrectly for a ra/dec

+	The maximum number of WCS attributes was increased from 256 to 512.
+	The WAT and WSV keyword handling code was modified to permit more
+	than 999 keywords to be output; the format changes to omit the
+	underscore if the index value exceeds 999.  These changes should be
+	backwards compatible while allowing more complex WCS to be stored.

+pkg/system/doc/rename.hlp
+	Modified the task to allow a destination directory to be specified
+	without changing the filename.  A new "field" parameter option "all"
+	was added and made the default so the entire filename is changed (or
+	moved in the case of a destination directory).  When field is set to
+	"extn" filenames without an extension will not have the new
+	extension appended so a filename isn't generated which can get
+	overwritten.  (3/14/95 MJF 4/19 DCT)
+
+pkg/cl/builtin.c
+	Appending the output of a foreign task now works correctly; previously
+	it would overwrite any existing output file.  For example, "ls >> foo"
+	will append the output of ls to file foo.  The bug addressed here
+	affected only explicit redirection of the output of a foreign task.
+	Previous version of the CL would correctly redirect the output of a
+	foreign task so long as the task was called indirectly, e.g. from
+	within a CL script.  (4/19)

+sys/etc/oscmd.x
+	Added clobber checking for the output redirection files if any.

+
+unix/shlib/mkshlib.csh
+	We had another one of those nasty occurrences where the iraf shared
+	library is rebuilt and suddenly nothing runs anymore (this happened
+	after the trivial modifications to oscmd.x above).  The problem was
+	traced to the setting of the "environ" pointer in low shared image
+	memory by vlibinit when the shared image is mapped by zzstrt.  The
+	environ variable is part of the Sun startup code and is one of the
+	first objects linked into the shared library image.  The problem was
+	that the data for this variable was located in the end of the last
+	page of text, but since the text was mapped readonly a segvio would
+	occur when attempting to write to this variable.  The fix, at least
+	for the moment, was to add a ".align 4096" to the end of V.s to
+	force the data segment to be aligned to a page boundary.  (4/20)
+
+sys/imio/iki/stf/stfdelete.x

+
+unix/hlib/zzsetenv.def
+	The default printer and stdplot devices were changed to "lp", which
+	on unix systems is the default line printer device.  If the user
+	has PRINTER set in their host environment IRAF printer output will
+	be directed to the user specified device.  The default printer
+	device may still be overridden from within IRAF by setting an
+	environment variable or via a parameter override.  (4/28)
+
+unix/hlib/libc/kernel.h
+unix/os/zawset.c
+	A number of changes were made to ZAWSET (called by BEGMEM) to improve
+	memory utilization for IRAF tasks that request and use very large
+	amounts of memory.  These changes should be backwards compatible and
+	the usages of ZAWSET and BEGMEM were not changed.
+
+	1. Modified to make it easier to determine whether the setrlimit
+	code is used on different platforms.
+	2. Removed the setrlimit that was being performed at process
+	initialization time to set the soft limit on a processes memory.
+	It is questionable whether this should be limited by default on
+	modern systems which are mostly personal workstations, and it
+	is better to use the "limit" command in the CSH (or equivalent)
+	to do this outside of IRAF, under user control.
+	3. In kernel.h, increased the default WSS to 8 Mb and the builtin
+	max WSS to 256 Mb.  These values are used only on platforms where
+	ZAWSET can't determine the value from the UNIX kernel, e.g. using
+	getrlimit.  Assuming MAXWORKSET is not defined (see below) the
+	max WSS value compiled into the IRAF kernel, e.g. 256 Mb, will
+	however serve as an upper limit on the amount of memory reported
+	as available to an IRAF task.
+	4. Added support for an environment variable "MAXWORKSET".  This
+	value if defined sets an upper limit on the working set reported
+	to a task via ZAWSET (or BEGMEM).  This can be used to override
+	the builtin upper limit.  If the platform supports getrlimit and
+	a memoryuse limit is defined which is less than MAXWORKSET, the
+	getrlimit value will be used instead: this the current limit,
+	as opposed to the maximum limit.  The units of MAXWORKSET are Mb,
+	e.g. "setenv MAXWORKSET 32" sets the maximum working set to 32 Mb.
+	Since MAXWORKSET is used by the host-level kernel code it must be
+	set in the host environment, not in IRAF.
+
+	A quick survey of SunOS, Solaris, and OSF/1 shows that the system
+	default getrlimit returns the amount of available physical memory
+	(57 Mb) on OSF/1, but an "unlimited" value (2 Gb) on the Sun systems.
+	The OSF/1 value is what zawset ideally wants to return, i.e. the
+	maximum amount of physical memory available to the process before
+	paging occurs.  This can be difficult to determine on many unix
+	platforms and currently the builtin kernel limit of 256 Mb will be
+	what is returned on platforms like SunOS/Solaris that don't report
+	the physical memory value.  With further research we may be able to
+	find a way to do reliably return the correct value on platforms
+	like Sun, however this can be a very system dependent feature to
+	implement.  In the meantime the MAXWORKSET environment variable,
+	or "limit" in the cshell (etc.) can be used to fine tune ZAWSET on
+	platforms that can't determine the max physical memory.  (5/02)

+	tucana.  Showed up right away when V2.10.4 moved to the user nodes.
+	(5/15)
+
+unix/os/zawset.c
+	On Solaris it turns out that setrlimit, when used to set the soft
+	memory limit, sets a hard limit on memory allocation for the process,
+	causing malloc requests to fail if the set limit is exceeded.  This
+	is not really the point of begmem/zawset, so the code was modified
+	to only call setrlimit if one attempts to increase the current "soft"
+	memory limit.  Requests for less working set than the soft limit
+	do not result in a call to setrlimit, and the routine merely indicates
+	that the requested space is available.  (5/15)

+sys/fmtio/evvexpr.gy
+	1. Modified the conditional expression code (xvv_quest) to consider
+	the dimension of the condition operand as well as that of the two
+	data operands when computing the dimension of the expression result.
+	For example, if the condition is a vector but the two data operands
+	are scalars, the expression result should be a vector (formerly it
+	was a scalar).  The datatype of the expression is still determined
+	solely by the datatypes of the two data operands.
+	2. The condition operand for a conditional expression may now be any
+	integer type, i.e. short or long as well as int, in addition to bool.
+	If int is permitted it doesn't make much sense to exclude short and
+	long.
+	3. The logical not code (e.g. "!a") was modified to permit integer
+	class operands (short, int, long) as well as boolean.  (5/27)

+sys/gio/gctran.x
+	The WCS transformation caching mechanism used in gctran was not

+	frequently than gctran was called.  To make caching of WCS related
+	information more robust a new field GP_WCSORD was added to the GIO
+	descriptor.  This is set to a unique integer ordinal when a WCS is
+	fixed.  If the ordinal changes any routines that cache WCS information
+	should invalidate their cache (unless they cache it on the basis of
+	WCSORD).  WCSORD will differ for WCS stored in different graphics
+	descriptors, so testing WCSORD also does an implicit test that the

+	When copying an image section IMIO will call MWCS to update the Lterm

+	was modified to put the mw_open in an iferr block, printing a warning

+sys/mwcs/imwcs.h
+	CROTA was being stored internally as an integer, causing small
+	truncation errors of non-integral rotational angles.  (10/18)
+
+dev/graphcap
+dev/imtoolrc
+	Added a new 8192x8192 frame buffer (imt7|imt8192).  Redefined the

+	New FWHM estimates based on the enclosed flux and a direct

+
+dev/hosts
+	Corrected path to irafks.e for cephus on all servers (11/30 MJF)
+
+unix/boot/spp/xpp/xppcode.c
+	Modified XPP to make keyword recognition case sensitive.  Keywords

+pkg/cl/prcache.c
+	1. Fixed minor bugs in the CL array code which showed up on the 64bit
+	DEC Alpha.  The array code had builtin assumptions about the size of
+	structures stored in CL memory, but on 64 bit systems the CL stack
+	and dictionary have a 64 bit memel size, rather than 32 bit.
+
+	2. Added a new builtin "d_trace" which permits instruction and
+	process tracing during execution.  Typing d_trace without any
+	arguments toggles this feature.  An optional argument 0 or 1 may be
+	used to disable or enable instruction tracing.  A source line trace
+	feature might have been nicer, but instruction tracing should still
+	be of use for tracking down bugs in scripts, or otherwise revealing
+	what is going on when the CL executes a task.  (12/16)
+
+sys/fmio/zzdebug.x
+	Added a parameter to the create datafile task to allow specification
+	of FM_MAXPTPAGES (max page table pages), for testing large datafiles.
+	(12/18)
+
+dev/hosts
+	Added new solaris machine oso to all servers. (1/29/96 MJF)
+
+pkg/images/imarith/imexpr.gx
+	Modified imexpr so that it will accept an image name that looks like
+	a number in the first few characters, but which is really an image
+	name.  For example, "123.imh" or "../foo.imh".  The previous version
+	of imexpr was treating any string which looked like a number in the
+	first few characters as a numeric constant.  (2/8/96 LED  2/14 DCT).
+
+dev/hosts
+	Eliminated all references to /gemini and /ursa since all machines
+	have been updated such that /iraf is the correct path.  Merged all
+	changes from other servers to tucana so all hosts files are now
+	identical, new machines added include ozzie, verdi, corondito and

+
+pkg/images/geometry/t_geotran.x

+pkg/images/doc/geomap.hlp
+         Corrected the definition of skew in the routines which, compute the
+	geometric interpretation of the 6-coefficient fit, compute the
+	coefficients from the geometric parameters, and in the relevant help
+	pages.  (2/19/96, LED)
+
+sys/fio/zzdebug.x
+	Spiffed up the "daytime" debug/test task to permit entry of a host

+
+pkg/images/tv/imexamine/iejimexam.x
+pkg/images/tv/jimexam.par
+pkg/images/tv/doc/imexamine.hlp
+	There were several errors in this which only showed up when using a

+	(2/27/96, FV)
+

+	The inverse WCS function was incorrect and is fixed.  (2/27/96, FV)

+	1. Changed the lfile pagemap (LF_PAGEMAP) from type short to int.
+	This is entirely an internal array, created at lfile open time from
+	the global pagemap, and never written out, so there should be no
+	problem changing the datatype of the array.  A type short lfile
+	pagemap limits the maximum datafile size by limiting the max file
+	offset to 32K datafile pages.  This is not a problem for the global
+	page table as the global table stores the lfile number in each PTE,
+	with the offset of the PTE entry giving the associated file offset
+	(page number).
+	2. Increased the default lfile pagemap size and increment on
+	overflow.  (3/11)
+
+lib/qpset.h
+sys/qpoe/qpoe.h

+sys/qpoe/qpseti.x
+sys/qpoe/qpopen.x
+sys/qpoe/qpmacro.x
+sys/qpoe/qpbind.x
+	Added a new parameter "maxptpages" (QPOE_MAXPTPAGES) to QPOE.  This
+	is a datafile control parameter similar to "maxlfiles" or "pagesize".
+	The pagesize and matptpages together determine the maximum datafile
+	size.  In the past we have had to increase the pagesize to accomodate
+	very large datafiles, but beyond a certain point it is better to
+	increase the maximum page table size (maxptpages).  Since QPOE files
+	can be very large it is necessary to allow control of this parameter
+	from within QPOE.  (3/11)
+
+dev/hosts
+	Added Doug Geisler's machine kukita to all servers. (3/11/96  MJF)
+
+sys/fmtio/dtoc.x
+	Added some rounding to avoid printing numbers such as 12:29:60.0
+	when formatting sexagesimal (HMS or MS) numbers.  (3/12)
+
+sys/mwcs/iwewcs.x
+	Modified the code which computes the CD matrix from CDELT/CROTA.
+	The old code computed the diagonal (scale) terms correctly but the
+	rotation terms were evidently incorrect.  The old code was based on
+	the 1988 Hanisch and Wells WCS paper and the new code is based on a
+	more recent paper by Mark Calabretta et. al. which supercedes the
+	1988 representation.  The affect of this change should be limited
+	as it only affects rotated images for which CDELT is given but no
+	CD matrix is defined.  (3/13)

+	The radial profile fitting and width measurements now have an option to
+	use a Gaussian or Moffat profile model.  The model is selected by a
+	new "fittype" parameter.  A new "beta" parameter may be specified as
+	INDEF to be determined from the fit or have a fixed value.  The Moffat
+	profile model does better in producing consistent FWHM values so
+	this is the default.  (3/16, Valdes)
+
+math/gsurfit/gsrestore.gx
+math/gsurfit/gsrestorer.x
+math/gsurfit/gsrestored.x
+	Changed the type declaration of the xmin, xmax, ymin, ymax variables
+        from real to PIXEL to avoid machine precision problems.  (3/21 Davis)
+
+pkg/cl/builtin.c
+	Modified the clprintf code to support INDEF operands.  (3/23)
+
+pkg/images/tv/imedit/epsearch.x
+pkg/images/tv/imedit/epgcur.x
+	1.  The search algorithm produced incorrect results if part of the
+	    aperture was off the edge (negative image coordinates).
+	2.  The rounding was incorrect when part of the aperture was off the
+	    edge (negative image coordinates).
+	3.  A floating operand error occurs when a key is given without
+	    coordinates.
+	(3/26, Valdes)
+
+pkg/plot/t_implot.x
+	When the vector being plotted was constant the 'l' and 'c' keys
+	selecting lines/columns from the right plot axis did not work.  The
+	code was fixed for this case. (3/27, Valdes)
+
+pkg/images/geometry/xregister/rgxfit.x
+        Changed several Memr[] references to Memi[] in the rg_fit routine.
+        This type conversion bug was causing a floating point error
+	in the xregister task on the Dec Alpha machines if the coords file
+	was defined, and could potentially cause problems on other machines.
+	(Davis, April 3, 1996)
+
+unix/os/gmttolst.c
+unix/boot/bootlib/ostime.c
+	Removed the type long variables gmtl, lstl and modified all calls to
+	localtime() so that the argument is of type time_t.  This is standard
+	for all modern systems.  Some older systems still require that the
+	argument be type long, but as this is nonstandard it should be
+	ifdef-ed in the source for these older systems.  (4/04 1996)
+
+unix/hlib/libc/libc.h
+	The macros Memcptr and Memiptr included a "+ 1" which shouldn't have
+	been there.  The one indexing correction was already being done in
+	the Memc/Memi macros and Memcptr/Memiptr take a zero indexed C pointer
+	as input.  This was causing a bug in LIBC version of realloc, which
+	is not used anywhere in the IRAF system code.  (4/05)
+
+pkg/images/tv/imexamine/ierimexam.x
+pkg/images/tv/imexamine/stfmeasure.x
+	Fixed incorrect datatype declaration "real np" -> "int np" in various
+	related places.  (4/9/96, Valdes)
+
+unix/os/zmain.c
+	Added a #ifdef SYSV conditional to change the calling sequence for
+	setpgrp() for SYSV and BSD systems.  (4/24)
+
+sys/imio/iki/plf/plfopen.x
+	Fixed an imerr() call which had the wrong argument type.   (5/06)
+
+sys/libc/realloc.c
+	Modified to work when called with a null pointer.  (5/06)
+
+sys/gio/stdgraph/stgdrawch.x
+	The text drawing routines were not controlling the polyline width
+	when drawing characters in software mode using polylines.  There is
+	no line width attribute for graphics text and we probably don't want
+	one, so the code was modified to force the line width to 1 when
+	drawing software characters.  (5/10)
+
+unix/boot/bootlib/osgetenv.c
+	The envinit code calls _os_getenv to fetch the value of "pkglibs".
+	This code assumes that _os_getenv returns the string argument, but
+	nothing was being returned if the named environment variable was not
+	found.  Changed it to return a NULL-terminated empty string in this
+	case.  (5/10)
+
+sys/etc/mkpkg
+sys/etc/onentry.x
+sys/etc/main.x
+unix/os/zmain.c
+	1. The IRAF main (irafmn) was changed to an integer function and
+	modified to return an exit status.  If a task aborts and the main
+	exits without running any more tasks (as when executing a task at
+	the host level where only a single task is run) then the error status
+	of the task is returned.  In normal use as a connected process this
+	condition never occurs and the main always returns XOK as the status.
+
+	2. Several calls to sys_panic in various etc$ routines were modified
+	to ensure that a zero error code is not returned.  sys_panic returns
+	the error code as the exit status of the process.
+
+	3. The process main (zmain.c) was modified to call IRAF_MAIN as an
+	integer function and to return its exit status.
+	4. The call to exit() in zmain.c was changed to _exit().  (5/11)
+
+pkg/plot/t_graph.x
+pkg/plot/graph.par
+pkg/plot/doc/graph.hlp
+	Added parameters "ltypes" and "colors" to specify a list of line types

+pkg/proto/doc/fields.hlp
+	Changed the default lines in FIELDS to an open upper limit.  (8/22 FV)
+
+pkg/images/tv/imexamine/stfmeasure.x
+	Fixed bug in evaluation of enclosed flux profile in which the scaled
+	radius was used for the gaussian subtraction stage instead of pixels.
+	This does not currently affect IMEXAM because the scale is fixed
+	at 1.  (8/29, FV)
+
+unix/os/zfnbrk.c
+	Modified this routine to ignore file or directory characters other
+	than those it considers to be file or directory name delimiters.
+	On platforms that permit it, the effect is to permit characters (such
+	as + and -) in filenames other than simple identifier characters.
+	There is no expectation at this point however that all IRAF code will
+	permit this.  (9/03)
+
+dev/hosts
+	Updated the hosts file on all Tucson servers for rainbow, Jim
+	Deveny's new Sun.  (9/10/96 jb)
+
+pkg/system/phelp.cl
+	Modified to copy the "template" argument into a local variable since

+
+sys/fio/fioclean.x
+	The file descriptor was being accessed after the file had been
+	closed.  (10/11)
+
+unix/os/zfiond.c
+	Added a ":<flag>" field to the ND network driver.  The only protocol
+	flags currently supported are "text" and "binary".  If "text" is
+	specified then the datastream is assumed to consist of byte packed
+	ascii text, and the driver will automatically convert to and from
+	SPP chars during i/o.  (10/29)
+
+sys/fio/zzdebug.x
+	Added a new debug task "http".  Given a hostname and a HTTPD-root
+	relative file path the task will connect to the HTTP server on the

+dev/hosts
+	Added driftwood to all downtown servers. (11/18/96 MJF)
+
+dev/hosts
+	Updated block of KPNO hosts on solaris tree on Gemini.

+
+sys/fmtio/sscan.x
+sys/fmtio/fscan.x
+sys/fmtio/clscan.x
+sys/fmtio/scan.com
+	Modified scan.com to dimension scanbuf locally as SZ_SCANBUF instead of

+
+pkg/images/tv/display/iishdr.x
+pkg/images/tv/display/iisers.x
+	Replaces SPP int -> short assignments by calls to achtiu because of

+	(12/6/96, Valdes as reported by Zarate)
+
+pkg/images/tv/display/imdmapfr.x

+Did a diff/merge of recent tucana HSI changes into the Solaris/IRAF HSI.
+Replaced the "unix" directory on tucana SunOS/IRAF by the version from
+Solaris/IRAF.  This HSI is supposed to work for both SunOS and Solaris
+(SunOS compatibility was preserved but never tested during the Solaris/IRAF
+port).  Did a bootstrap and sysgen under both SunOS and Solaris.
+
+Mounted tucana iraf.develop as iraf.develop on Data.  tucana iraf (irafx)
+is now solaris/iraf as well as sunos/iraf, they are the same thing.  One
+benefit of this is that irafx is now available on solaris systems in the
+building (although we do have to update the ssun binaries periodically or
+it does no one any good).   A complication is that since we have to update
+the ssun binaries, it is now more likely that the architecture may be set
+to something other than sparc.  (3/19 1997)

+--------------------------------
+The following series of revisions were made to increase the size of various
+system buffers.  This included a full system reboot and recompile.  (3/24)
+
+lib/fio.h
+sys/fio/vfnmap.x
+sys/fio/vfntrans.x
+	Various buffer sizes affecting filename mapping were increased.
+	SZ_VFNFN (max length of the root field of a VFN) went from 32 -> 127.
+	SZ_OSDIR (max length of the osdir field of a VFN) from 79 -> 255.
+	SZ_FFNAME, an internal filename buffer, went from 127 -> 255.
+	In an unrelated change SZ_SPOOLBUF, the intial size of a spool
+	buffer, was increased from 1024 to 4096.  (3/23)
+
+unix/hlib/config.h
+	1. MAX_ROOTLEN was increased from 32 to 128.  This is supposed to be the
+	limit the host system places on the root portion of a filename (that
+	is, only the root name, not the pathname).  Anything in the range
+	128-256 is typical for unix systems today.
+	2. The maximum number of open VOS files was increased from 128 -> 256.
+	(3/23)
+
+sys/fio/fntgfn.x
+	SZ_PATTERN, SZ_TEMPLATE, SZ_LDIR, SZ_PATSTR were all increased,
+	although so far as I know there has never been a case of pattern
+	buffers overflowing.  The new limit for a pattern string is about
+	1024.  (3/23)
+
+unix/hlib/iraf.h
+	SZ_FNAME went from 63 -> 255.
+	SZ_PATHNAME went from 127 -> 511.
+	SZ_LINE went from 161 -> 1023.
+	SZ_COMMAND went from 1024 -> 2047.  (3/23)
+
+unix/hlib/iraf.h
+unix/hlib/mach.h
+	MAX_EXPONENTD went from 38 (same as real) to 308, the value for
+	IEEE double.  MAX_DOUBLE increased from 0.99d37 to 0.99d307.
+	INDEFD was changed from 1.6d38 to 1.6d308 for IEEE systems.  (3/23)
+
+unix/hlib/libc/libc.h
+unix/hlib/libc/spp.h
+	FIO_MAXFD, INDEFD, SZ_LINE, SZ_FNAME, SZ_PATHNAME, SZ_COMMAND were
+	updated to agree with the SPP values.  (3/23)
+
+sys/imio/iki/stf/stfrdhdr.x
+	Unrelated STF bug fix.  stfrdhdr.x was modified to handle the case
+	where datamin/datamax were not defined in the GPB, but were defined
+	in the main image header.  (3/24)
+
+unix/boot/spp/xpp/xppmain.c
+	Removed a redundant SZ_PATHNAME.  (3/24)
+
+unix/shlib/mkpkg
+unix/shlib/mkshlib.sos4
+	Changed the address of the shared library from 0xa000000 to 0x10000000.
+	This increases the maximum available per-process dynamic memory from 
+	167 MB to 268 MB (much more is possible if the process is statically
+	linked).  (3/24)
+
+unix/os/zzstrt.c
+	Changed some address-related ints to unsigned just to be safe.  (3/24)
+
+sys/etc/pagefiles.x
+	Increased SZ_LONGLINE from 1024 to 4096.  At 1024 it was the same as
+	the new SZ_LINE, causing a loop test to fail.  (3/25)
+
+pkg/images/tv/rimexam.par
+pkg/images/tv/doc/rimexam.par
+	Changed the zero point of the magnitude scale from 30.0 to 25.0

+
+pkg/images/tv/imexamine/ierimexam.x
+	The log output for 'a' or 'r' has one line per measurement as in

+lib/imhdr.h
+lib/imio.h
+	The sizes of the pixel file, header file, title and imhistory strings
+	were increased.  Defines were added for the image header file and

+	It was necessary to change the OIF kernel to increase the maximum
+	path length for header and pixel files.  This made it necessary to
+	change the disk image format, since the old format only allowed 80
+	characters for the pixel file pathname.  In the process reading and
+	writing the disk header was separated out from the in-memory
+	header.  Support for two versions of the image and pixel file
+	headers were added.  The "magic" string in the image or pixel file
+	header identifies the version.  Old (version 1) image headers have
+	"imhdr" at the head of the file, with the string in SPP chars.  The
+	new (version 2) headers have "imhv2" as the magic string.  V2 headers
+	are byte packed and machine independent.  The path limit is 255.

+	1. Support was added for byte swapping pixels.  With the machine
+	independent V2 image header, this allows .imh images to be read on
+	any node (integer) or any IEEE-compatible node (floating).  The
+	pixels are written in the native swap order of the creating host,
+	but the order is recorded in the IM_SWAPPED field of the image header,
+	and IMIO uses this to determine whether or not the pixels need to
+	be byte swapped during i/o.
+	2. Minor changes to trim junk data after EOS delimited strings.
+	Since the V2 headers are byte packed the string data in these headers
+	can be viewed with Unix tools such as "less" and "strings".  (3/31)
+
+	Some pointers: "strings foo.imh" (or other tools like less) can be
+	used at the Unix level to look at V2 image headers.  New images are
+	always written with host-native binary format pixels, so there is no
+	byte swapping involved for images read and written on the same
+	host.  Images can any other (IEEE) host can be read or written but
+	there may be some slight overhead for byteswapping.  If the image is
+	rewritten however using imcopy, the bytes will be swapped to the
+	native ordering of the new host.
+
+pkg/images/imutil/src/imheader.x
+	The only change so far was to eliminate some histogram dependence,
+	since this unused feature was removed from the standard IMIO in-memory
+	image header.  (3/31)

+unix/hlib/login.cl
+	Increased the default size of the user area (min_lenuserarea) to
+	64000 (about 800 80 char cards).  There was some ambiguity about
+	units for min_lenuserarea; it should be consistently chars now.
+	Also increased the "padding" added to the header when creating a
+	new copy of an existing image which has a large header.  (4/01)
+
+sys/imio/immaky.x
+	When the header of an old image is copied during an open-new-copy,
+	IMIO now recomputes the length of the user area of the input header.
+	Formerly if the header had grown since the image was opened, the
+	added data could be lost in a subsquent new-copy operation.  (4/01)
+
+sys/etc/oscmd.x
+	Changed an fclobber(outfile) to fclobber(errfile).  (4/02)
+
+sys/imfort/bfio.x
+	The little Fortran-callable file i/o package BFIO used in IMFORT
+	was enhanced to support writing and reading of fractional file blocks
+	so that files can be any size.  The default random and sequential
+	buffer sizes were increased.  In addition to the old random access
+	i/o routines bfread/bfwrite there are now sequential i/o routines

+	1. IMFORT was brought up to date with IMIO to read and write the new
+	version 2 ".imh" images.  As with IMIO, the old V1 format is still
+	supported but new images are written using the new machine independent
+	V2 format.
+	2. Image headers can now be any size (the old IMFORT had a very
+	strict limit on the image header size).  Since BFIO now writes partial
+	blocks, headers are no longer blocked out to 32768 bytes.
+	3. "min_lenuserarea" is now supported as for IMIO (since IMFORT is
+	host level it must be defined in the host environment).  The builtin
+	default header buffer is 64000 chars, which is about 800 card images.

+	[INTERFACE CHANGE]
+	The calling sequence for qpio_readpix was modified to replace the

+	NOAO (including xray) currently uses this routine.  (4/04)
+
+sys/plio/plrio.x
+	The plrio package provides an efficient lookup-table-based means of
+	randomly sampling 2D pixel masks.  The code which recursively divides
+	a region into 4 quadrants could fail if the region being subdivided
+	was 1 pixel wide in either axis.  If this happens 2 of the "quadrants"
+	will be valid and 2 will be degenerate.  Added a test to detect and
+	discard these degenerate subregions.  (4/04)
+
+sys/plio/plsectne.x
+sys/plio/plsectnc.x
+	Both of these routines had a bug that could prevent them from
+	examining the full region requested (the routines check for section
+	not empty and section not constant).  Line lists are segmented in
+	segments of at most I_DATAMAX (4095) pixels.  If the mask is large
+	and has large regions of constant value, the list will consist of
+	successive segments all at the same value.  The routines were only
+	checking the first such segment.  The corrected code reads successive
+	segments until all the pixels in the region have been examined.  (4/04)
+
+sys/plio/zzdebug.x
+	Fixed a couple of bugs and added several new routines to test the
+	above fixes.  SECNE and SECNC test pl_sectnotempty and pl_sectnotconst.
+	RIO tests plrio random mask access.  INVERT inverts a mask.  (4/04)
+
+sys/imio/implhdr.x
+	These routines, which copy an image header to and from an encoded title 
+	string in a PLIO save file, were modified to save the ctime, mtime,
+	limtime, minpixval, and maxpixval static fields of the image header
+	in addition to the title string.  (4/04)
+
+sys/qpoe/qpexeval.x
+	The value of "pass" was not being initialized before starting
+	subprogram execution when evaluating a complex LUT bin.  Added the
+	initialization and also some comments giving an overview of how the
+	evaluation is performed (since it took me several hours to figure
+	this out again).  (4/04)

+sys/imio/iki/qpf/qpf.h
+	Modified to support separate x and y blocking factors.  (4/05)
+
+sys/plio/plupdate.x
+	This routine contains code which collapses successive mask lines
+	in Y to a single encoded mask line if the mask lines are equal,
+	thereby compressing the encoded mask in Y.  The encoded mask lines
+	are encoded in short integer arrays and a multiply referenced
+	line has a reference count which is stored in a short integer field.
+	The code was modified to stop when this counter reaches MAX_SHORT,
+	adding a new line to the encoded mask and starting over.  Combined
+	with the X segmentation of lines into blocks of at most 4095 pixels,
+	this should allow masks to be nearly any size despite the use of
+	short integers for the encoding.  (4/05)
+
+sys/qpoe/qpiolwcs.x
+	Modified the LTV_2 term of the logical transformation to set the
+	fractional pixel zero point resulting from blocking the input data.
+	If for example 2 input pixels map to 1 on output, the range of the
+	output pixel (e.g.  0.5 to 1.5) maps to the range covered by the two
+	input pixels (e.g.  0.5 to 2.5), and the center of the output pixel
+	(e.g.  x = 1.0) maps to the center of the range spanned by the input
+	pixels (e.g. 1.5).  For 3 to 1, 1.0 maps back to 2.0 in the input,
+	for 4 to 1, 1.0 maps back to 2.5, and so on as (block+1)/2.  (4/05)
