+Subject: I/O redirection support for IRAF/VMS
+ 
+Added the ability to do I/O redirection on the command line (Unix-style).
+
+	interactive	$ cl
+	i/o to files	$ cl  <infile  >outfile     (or >>outfile)
+
+This allows people to run the CL in a VMS batch job or as a "background" 
+subprocess, specifying the CL commands in a text file.
+
+
+sys$os/zmain.c
+	Added code to support I/O redirection  (parsing, file setup, etc.)
+
+sys$os/zfiotx.c, zfiofi.c
+	Fixed ZSEKTX to work correctly (had troubles with redirected i/o for
+	some reason).
+
+	Changed append mode access so it has RMS Update access (for seeking).
+
+pkg$cl/exec.c
+	Added a global variable 'logout_on_eof' (default=0), which is set
+	by the VMS ZMAIN when I/O is redirected to files.  If the user forgets
+	to put the 'logout' command in the infile, then EOF will get him out.
+	Otherwise, it's very easy to fill up a disk with "ERROR: use 'logout'.."
+	messages in a file, something we definitely want to avoid.
+
+	This is only a TEMPORARY fix.  The same thing happens under Unix, so 
+	maybe their should be some way of handling this in a general,
+	system-independent way.  Will users use the CL with input from a file 
+	instead of the terminal?  They are here (for now) and the capability 
+	should probably be supported, since it is automatically supported 
+	under Unix.
+
+	This fix does not affect normal operation of the CL in interactive mode;
+	the user still has to say 'logout' to get out of the CL.
+
+	Note:  If a user has a parameter which has a range specified, and the
+	value is out-of-range, while running the CL in this "OS-background"
+	mode, it will probably just loop until death saying "parameter out of
+	range", and fill up a disk with these error messages.  This is also
+	a problem, but not sure how (or if) to fix it; the user should make
+	sure that the parameters are indeed correct when running the CL this
+	way to avoid this problem (?).

+Subject: pkg$cl/eparam.c
+ 
+Hacked EPARAM to fix a number of problems with multi-line prompts, arrays,
+and other things.  There are still a few known "features", but they are so
+obscure and such special cases that I'm not going to worry about them now
+(there are easy ways to "reset" eparam to fix these offset problems).
+
+Also, changes so that value field is not overwritten by prompt string.

+Subject: Parameter cacheing  (pkg$cl/exec.c)
+ 
+Parameter cacheing mechanism (pkg$cl/exec.c  mk_startupmsg, sys$etc/main.x,
+clio$clcache.x, etc.) does not handle array parameters.  Eventually, it should,
+but this will mean some non-trivial changes in all of these places.  There
+are a few places in SDAS that do indeed have array parameters, so the course
+of action for now is to not pass them in the startup message (as is done with
+list-structured parameters).  This fix is a simple "if" statement in exec.c/
+mk_startupmsg().

+ 
+Changed to generate the CLDATE file in MACRO rather than C (i.e. cldate.mar).
+This is so IRAF/VMS sites don't need a C compiler to relink IRAF (one site had
+this problem already).

+Subject: sys$os/  [VMS Kernel]
+ 
+The VMS Kernel routines have been overhauled.  The large number of changes
+consisted of: deleting obsolete code, consolidating common code segments,
+some name changing, improving readability and consistency, and some tweaks
+for efficiency.  Most of the changes were indeed cosmetic, in an effort to 
+bring the code into conformance with the IRAF coding standards (though perhaps
+not 100% there).  To list all the changes would be impossible, so here are
+some of the major ones...
+
+A number of files have been renamed, as well as support routine names, to be 
+more descriptive (and to remove the "z" on many of the support routine names).
+
+File name changes:
+	zconvtim.c  -->  convtime.c
+	zexit.c	    -->  exit.c
+	zget*.c     -->  get*.c
+	zprocname.c -->  procname.c
+	ztrnlg.c    -->  tranlog.c
+	zfiofi.c    -->  rms.c
+	ast.c	    deleted (no longer needed)
+
+Function name changes:
+	_zopnfi, _zclsfi  -->  _rms_open, _rms_close
+	_ztrnlg, _zcrelg  -->  _tranlog, _createlog
+	_zrequestio       -->  _zqio
+	_zsttfi		deleted
+	others...
+
+New files:
+	dirname.c
+	queue.c
+	eprintf.c	(from Kitt Peak, VMS net stuff)
+
+The file status functions (formerly in _zsttfi) have all been moved into each
+of the ZFIO* drivers, with appropriate buffer size values in the include file
+"vms.h".  Some of these values have been modified, where appropriate, or as a
+result of recommendations from Kitt Peak.
+
+No effort was made to completely redesign anything, though some files and
+routines were restructured quite a bit.  The effect on executable sizes of 
+these changes is negligible.
+
+--------------------------------
+Friday  22-NOV-1985 10:43:50.93
+ 
+Subject: pkg$softools/boot/...
+ 
+All of the VMS source code for the boot utilities (MKLIB, XC, support ...)
+have been overhauled to look like the rest of IRAF (at least partially), just 
+as the VMS Z routines.  Besides a few name changes because of Z-routine
+name changes, there was only 1 functional modification:
+
+	pkg$softools/boot/spp/xc.c	[VMS]
+			     /dcl.c +
+		Changed to use the function DCL instead of ZOSCMD.  DCL does
+		everything ZOSCMD does without all the weird features to 
+		support interactive commands.  The output is much more 
+		consistent here as well, no longer generating ".;" and ".LOG;"
+		files all over the place when running XC and MKLIB in batch
+		or background.  (DCL is essentially an earlier, stripped-down
+		version of what eventually became ZOSCMD).
+ 
+--------------------------------
+Monday  25-NOV-1985 15:41:56.73
+ 
+Subject: Support for VMS batch jobs
+ 
+The VMS kernel has been modified to support VMS batch jobs as well as
+parallel subprocesses for IRAF background jobs.  Changes in the higher level
+IRAF code is necessary to selectively use these two options.  Since the
+calling sequence for ZOPDPR has been changed, the new one is currently 
+commented out until these higher level changes are finished (at Kitt Peak).
+
+[received CL and system lib changes, 9-DEC]
+
+The changes include:
+
+	ZOPDPR -- extra parameter 'batch_queue', null or "" for subprocesses,
+		  a batch queue name for a VMS batch job.  A few new routines
+		  in this module were added and everything was reorganized a
+		  bit.
+
+	ZMAIN  -- some extra checks were added to deal with the batch case.
+
+	ZFIOTX -- In ZSEKTX, added a check for STDIN/STDOUT when a VMS batch
+		  job.  This is necessary to avoid seek errors on NLA0: and
+		  the batch log file.  (VMS really makes it hard to deal with 
+		  I/O in a consistent manner.)
+
+	queue.c - Contains VMS batch and print queue support functions.  Used
+		  by ZOPDPR and ZFIOLP.
+ 
+--------------------------------
+Monday   2-DEC-1985 09:40:50.23
+ 
+Subject: pkg$cl/builtin.c
+ 
+Changed SZ_FNAME to SZ_PATHNAME in cledit() to handle longer VMS filenames
+resulting from filename mapping.
+ 
+--------------------------------
+Monday   9-DEC-1985 08:27:39.00
+ 
+Subject: pkg$cl/prcache.c
+ 
+Interrupts were not being enabled if connected subprocess create failed.
+Added call to intr_enable() in before returning NULL.

+Tuesday  10-DEC-1985 12:39:20.67
+ 
+Subject: New version of IRAF/VMS from Kitt Peak.  Merge notes:
+ 
+sys/os/*
+	Remerged the VMS kernel.  No major problems, even though we both had 
+	made a number of changes.  Will test it all out soon.
+
+sys/os/net/decnet.c +
+	   zfioks.c
+	   Makelib
+	   eprintf.c --> ../
+
+	Added support for DECnet, though this is not fully tested yet.  This 
+	is a compile time option (DECnet or TCP) in ZFIOKS and will not affect
+	the TCP implementation.  The eprintf.c file was moved to the sys/os/ 
+	directory, since some debugging code there uses it now as well.
+
+sys/gio/gks/gtx.f
+	Did NOT use KPNO version of file since it was calling f77upk with
+	the wrong number of arguments.  There is no min-length arg to f77upk
+	in either version of IRAF.
+
+sys/osb/f77pak.f
+	Changed DO loop to pop out when done, rather than going around until
+	it reaches 9999.
+
+sys/gio/ncarutil/sysint/uliber.f
+	Following change need to compile on VMS.
+		integer*2(80) sppmsg  -->  integer*2  sppmsg(80)
+
+pkg/images/imarith/imadiv.x
+		   imamax.x
+		   imamin.x
+		   (>>> imarith.x)
+	POINTER --> PIXEL
+
+pkg/imred/generic/Makelib, x_generic.x, generic.cl
+	Removed references to 'cmdstr' in these files.  Assumed 'cmdstr' was
+	moved to the system pkg, since no cmdstr.* files on the tape. (?)
+
+sys/fio/vfnmap.x
+	Reference to ztslee changed to zwmsec.
+
+pkg/system/x_systest.x
+	Removed reference to mtdevlist.
+
+pkg/images/tv/display/t_mkdisplay.x
+	Moved call to open_display_header to AFTER getting name of stdimage
+	and frame number.  Was before it, resulting in dev$_0.imh, instead
+	of dev$deanza_1.imh.
+
+pkg/language/doc/*.hlp
+	Some of these files were updated recently to correct errors, typos,
+	misspellings, etc.  Forgot to note these changes before.
+
+Testing re-merged system
+	Tested out a number of the usual things: CL, test scripts, SYSTEM and
+	LISTS pkgs, some graphics and image tasks, etc.  Everything seems to
+	be working okay.  There are still a number of known bugs, especially
+	in eparam and procedure scripts (history gets a 'begin' in the history
+	for procedure scripts).  I'll be looking into these again soon.
+
+VMS Batch Jobs
+	Tested out the CL with both types of background jobs, subprocesses and
+	batch.  Both work fine.  A logfile for the batch job case is kept
+	in the user's sys/login directory with a name like "12345678_D_1.LOG",
+	(i.e., like detached subprocess names).  This logfile is largely
+	login garbage, but if the user does not redirect output, it will go
+	here as well.  When things settle down and everything is working okay,
+	we may want to have the logfile deleted, or add an option for keeping
+	it or not.
+
+	Logical names for batch queues work as expected.  For example, the 
+	following can be done:
+
+		$ define  b  sys$batch
+		$ define  f  localfastbatch
+		$ define  s  localslowbatch
+			...
+
+		cl> task >&task.out &f	   # IRAF bkg job to 'localfastbatch'
+
+	This means that zopdpr.c can remain system-independent, with system
+	dependent batch queues set up in logical names or spelled out fully
+	when in the CL.
+
+Magtapes
+	Tested the tape stuff with all the new changes from Kitt Peak merged
+	in.  Used mtexamine and rfits and was able to read in about 20 small
+	FITS images and run some tasks from the images and plot pkgs on them 
+	with no problems.

+Added NEXT_PAGE and PREV_PAGE sequences to edcap files for EDT, EMACS and VI.
+
+edt --
+	NEXT_PAGE        \033Ow		 keypad-7
+	PREV_PAGE	 \033OP\033Ow	 gold-7
+

+ 
+Subject: pkg/cl/builtin.c
+ 
+Fixed a bug in clflprcache() so that everything is not flushed if the named
+task is not found in the process cache.  Previously, if a user said 
+
+	cl> flprcache notask
+	Warning: 'notask' not in cache
+
+Then everything would go anyway, including locked tasks.  The fix is simply
+to do a 'continue' in the while loop when we print out this warning message.
+ 
+--------------------------------
+Wednesday  18-DEC-1985 18:44:37.98
+ 
+Subject: sys/fmtio/lexdata.xi
+ 
+Changed action table for  +/-  in state QRX from Rvt to QRX.  This is to fix
+a bug when getting numbers like 1.0e-10 which returned nchars=3 instead of
+nchars=7.  This code is (eventually) used to check the type of command line
+arguments in the CL when lexmodes=yes, which is where the problem was first
+noticed. 
+
+The code in lexnum.x along with the action table are somewhat difficult to
+follow and there may be other implications here which are not apparent, but
+based on other entries in the table, this looked like it was indeed a bug.
+Ran the debug code in sys/debug/nop.x (lex task) and things worked correctly
+in all cases tested.
+

+Friday  20-DEC-1985 11:42:48.72
+ 
+Subject: VMS batch jobs and DCL commands
+ 
+When running a DCL command as an IRAF/VMS batch job (e.g. a foreign task), if
+the output just goes into the logfile, it ends up being written into files with
+names like .;1 and .;2, etc.  This goes back to all the old crazies with the
+funny ZOSCMD to defeat slow spawning and still provide interactive
+capabilities.  The user should redirect output in this case somewhere else and
+not let it go to the VMS logfile.  Tried a few changes in zoscmd.c and open.c
+to no avail, so I'm just going to let this slide for now. 
+

+Subject: pkg/system/help/Help.hlp

+ 
+--------------------------------
+Monday  23-DEC-1985 10:35:15.82
+ 
+Subject: Help task (discussion)
+ 
+Some SDAS users have voiced a "concern" over the help task.  When saying "help
+abc", everything that matches "abc" is given, even if something has already
+matched it in the current package.  This is confusing to novice users, even
+though it is documented in the help that it will perform this way.  A more
+concrete example: 
+
+	cl> system
+	sy> help co
+		... concatenate
+		... copy
+		... count
+		... imred.coude
+		... language.command
+		...
+	
+Would it be possible (and/or desireable) to stop the searching if help is found
+somewhere in the current package for a named task or abbreviation?  
+
+Another problem is getting help on something in a different package than what
+was intended because of a common abbreviation (and no help file for the task in
+the current package).  The fix for this might be to limit the help search to
+the current loaded packages, unless an explicit pkg-template.module-template
+were given by the user. 
+
+To go one step further, a suggestion by some SDAS people was to have an extra
+parameter that controlled the search.  For example, if matchall=yes, then help
+would act as it does currently, otherwise, it would only search the current
+package.

+Subject: CL Changes  Nov-Dec 1985
+	 (T.McGlynn, J.Travisano)
+
+grammar.y
+	- delete opnl's in procedure declarations to eliminate s/r conflicts.
+	- create LP and RP for parentheses to eliminate some expressions.
+	- repositioned initialization processing.
+	- modified var_decls slightly.
+	- if/else fixes, so don't need { if ... }.
+	- better syntax error reporting in scripts: gives (correct) line number,
+	  points to offending position, and continues parsing script for errors.
+
+history.c  gram.c
+	- changes to support above grammar changes
+
+history.c  exec.c  pfiles.c  decl.c
+	- changes to deal with script line numbers correctly, i.e.
+	  task->t_scriptln, which is used in syntax error messages; also,
+	  a fix in the skip_to() function in decl.c.
+
+history.c
+	- problem of getting a "begin" in the history when running (or parsing)
+	  a procedure script was fixed.  The original command is now recorded
+	  in the history (and logfile) correctly.  Unfortunately, there is
+	  one case where this does not work -- when get an error parsing the
+	  parameter declarations in a procedure script.
+
+eparam.c
+	- format changes for real arrays (so exponent shows up)
+	- tried to fix MOVE_END problem when going across page boundaries;
+	  can't seem to find the bug, so for now just print out a message that 
+	  says to use NEXT_PAGE a few times instead of MOVE_END.
+
+pfiles.c  param.c  gram.c
+	- added support for '\r' and '\f', so can be used in prompt strings 
+	  for better formatting control  (\f not fully supported in EPAR yet)
+
+modes.c  decl.c  pfiles.c
+	- whitespace-only filename parameters are turned into null strings;
+	  so users can check null filenames easily in a script (fn != "")
+	  without having to deal with whitespace.  Filenames with whitespace
+	  only are not really legal anyway (?).
+
+modes.c 
+	- bug fix to prevent trashing of enumerated parameters in certain
+	  instances.  
+
+param.h
+	- minor typo   'ai' --> 'ar'
+ 
+--------------------------------
+Friday  27-DEC-1985 14:47:48.01

+The following is another lexmodes=yes problem:
+
+	pl> contour img1[*:16,*:16]
+		...
+	pl> surface ^^
+	surface img1[*:16
+	Warning: ...
+
+The get-arguments code in pkg/cl/history.c checks for comma-delimited strings.
+Putting the whole argument in quotes, i.e. "img1[*:16,*:16]", and then using
+^^ works fine.  (No fix/change was made.)

+ 
+Subject: Local vars in CL procedure scripts
+ 
+It is generally assumed that local variables in CL procedure scripts, i.e.
+those after the "begin" statement, will be initialized by the user with 
+simple assignment statements.  There is one (possibly more) case where this
+assumption can cause problems.  For example,
+
+			...
+		begin
+			string  buf
+
+			if (fscan (plist, buf) != EOF) ...
+			...
+
+Here, "buf" is used before being initialized, and the result is an error
+saying "Attempt to use uninitialized local variable 'buf'".  Perhaps local,
+uninitialized variables should be initialized automatically by the CL, but
+have done nothing to fix/change this yet; just making a note of it.

+Tuesday   7-JAN-1986 15:37:59.59
+ 
+Subject: Miscellaneous
+ 
+These are various notes and suggestions by IRAF users at STScI and elsewhere.
+I decided to finally add them all here since they were beginning to pile up
+on various scraps of paper on my desk.  Some of them are minor bugs, but most
+are suggestions of some kind.  Nothing has been done with any of them in terms
+of IRAF changes.  Most of the text is from mail messages or typed in verbatim 
+from paper copies.  Any notes by me (JayT) are indicated in brackets [].
+
+
+From ST users:
+
+CL
+   Would it be possible to put a feature into iraf whereby you say
+'task=xxx', which would then set a default so that you could just 
+type lpar, or an input, without having to specify which task?  
+Ie, instead of having to type 'xxx.infile=etc', you could specify
+the task and then just type 'infile=etc', with iraf filling in
+the task name.  This would not interfere with those who like the
+system as it is, but could streamline things for those of us who
+like the way AIPS does things.
+
+Integer parameters
+  We have encountered another peculiar feature of IRAF.  Suppose you have a
+parameter that is declared as integer in a .par file, and the user attempts
+to put in a value for that integer that exceeds the range of INT*4.  The cl
+fills in that parameter with the value 'indef', a character string.  When
+SDAS goes to read the parameter, we get a crash because the parameter is not
+in integer form.  Now, it seems that a parameter declared as an integer ought
+to be an integer no matter what, not a character string.  Wouldn't it be better
+to leave the parameter value unchanged from its current or default value rather
+than put in this string?
+
+
+From RAL users:
+
+CL Parser
+	li> ?? | words | match ':' stop+| sort | table
+
+	does NOT work correctly, but separating the "+|" to "+ |" works okay.
+
+Help on parameter prompt
+	It is very complicated to provide additional help at the prompt for
+	parameter stage especially for non-string parameters.  This facility
+	is almost essential to provide a user-friendly interface. 
+	For example:
+		A string specified in the parameter file is output if ? is
+		typed in response to a prompt or possibly even enter the help
+		system.
+
+	[NOTE: One can make the prompt quite verbose, up to something
+	like 2K characters; e.g., many SDAS prompts are long and multiline.]
+
+Range check and default display in sexagesimal
+	There needs to be an option in the parameter file to cause the range
+	check and default information to be output in sexagesimal.  For example,
+	it is ugly to type in 12:34:56.7 and have it reappear as 12.582417.
+
+Date type
+	I think there ought to be special facilities for handling dates.  At
+	present you can't enter a date all in one line (except using a
+	grotty fudge involving sexagesimal, which precludes proper range
+	checking), and if you enter the Y,M,D separately you can get things
+	like 1985 2 30 past the range checks.
+
+
+From U. of Cal/San Diego (Doug Tudhope):
+
+lists.gcursor [and imcursor]
+	Get syntax error line 2.  [known "feature" since CL2 grammar]
+
+	[NOTE: doing an "lpar gcursor" activates the graphics cursor, 
+	but then get an error of "EOF encountered in list parameter..."]
+
+plot.graph task

+ 
+Added EXTEND_SOURCE option for calling Fortran compiler from XC.  This lets
+source statements go up to column 132 (instead of 72).  One line added to
+source:
+
+fcompile() {
+	...
+	sp = strcpy (outbuf, F77);
++	sp = strcpy (sp, "/EXTEND");	/* Allow statement in cols 1-132 */
+	if (portable)

+Deanza now works with tv/display under VMS!  All of the source files and Deanza
+libraries are here.  See the README file for more detailed information.
+
+Also changed "pkg/image/tv/display/mkpkg.com" to make the Deanza code instead
+of the IIS-dependent code.

+Subject: pkg/imred/.../*.e
+ 
+The ONEDSPEC executables are copied all over the place into IMRED.  Comments in
+the mkpkg.com files say this is to use different par files for different
+directories.  There's GOT to be a better way, as this eats up a lot of
+diskspace (and tape as well at distribution time), which we always seem to be
+running up against here.

+Subject: More SDAS concerns/suggestions
+ 
+Environment variables
+	When a script task ends or a user bye's from a package, all "set"
+	declarations made in the task or since the package started are
+	"popped" during task restoration.  Comments in pkg/cl/exec.c indicate
+	that this is for keeping the environment the same across processes.
+
+	However, this can lead to confusion.  If a user does a "set stdgraph="
+	and later bye's out of a package, stdgraph reverts back to the 
+	previous value, just as any other environment variable.  The same
+	thing occurs in script tasks during the restore, making it difficult
+	to have global environment variables.  Putting a "keep" in scripts at
+	various places can get around this to some degree, but it's sometimes
+	awkward.
+
+Process cache
+	SDAS has been set up under IRAF such that the user can choose which
+	version of SDAS he wants (baseline|standard|develop).  This choice
+	can be made when starting the sdas package or any of its packages.
+	There is a problem, however, when running a package from 'standard'
+	and then running the 'develop' version when the executable is already
+	out there.  When a task is invoked, it will simply use the subprocess
+	already in the cache, even though it's a different executable (with
+	the same IRAF logical name).
+
+	The suggestion that came up was to do an implicit "flprcache" whenever
+	there is a "bye" to a package, i.e. when all the tasks associated with
+	the executable are gone.  I've looked at this a little bit and don't
+	see an easy way of determining when we're bye'ing from a package which
+	has tasks that are in an executable.  I imagine there's a decent amount
+	of overhead associated with checking all the tasks associated with
+	an executable as well.  In general, getting rid of old executables
+	does make sense if they're not longer referenced, since it frees up 
+	system and user resources (especially important on VMS given the
+	large process and executable sizes).
+
+Table parameters
+	SDAS and CDBS now have a new type of input file, a table, which may or 
+	may not have a header as well.  They have asked if it would be easy
+	to add a new parameter (or two) to IRAF, i.e. a table parameter and
+	possibly a table-with-header parameter.
+
+	I don't think this is a good idea, as it is something which only
+	benefits SDAS and CDBS, and does very little if anything for IRAF.
+	I have encouraged the SDAS people to find an SDAS-only solution to
+	this problem using existing IRAF facilities.  One simple way is to
+	have tasks which use tables to have a 'type' parameter which tells
+	if the input file is a table or something else.

+Subject: Size of IRAF...
+ 
+A concern has risen, once again, on the size of IRAF.  Garrett Jernigan
+(Berkeley Space Sciences Lab) has mentioned problems finding diskspace to
+handle all of IRAF.  The suggestion he made to Peter was "to split the source,
+obj and executables into separate libraries for the distribution, or at least
+put them into different sub-directories.  If either a tape could be generated
+that only had executables, or that had the whole works, but allowed only the
+required files for execution to be loaded it would be a real boon."  I guess
+this means having something analagous to the bin/, src/ scheme in Unix.
+
+I think a better solution to this is to add something to the installation docs
+to describe how to load only parts of IRAF, i.e. everything, or no source,
+etc., so the IRAF installer can load only the parts needed/desired.  Both Tar
+and Backup can handle selective copying in some manner.

+Subject: CL strings
+ 
+It is currently impossible to get the length of a string in the CL.  This
+should be quite trivial to implement, but it is not.  The documentation on
+"paramaters" states that p_length contains the maximum length of the string,
+though in reality, saying =param.p_length simply prints the string, just as
+=param does. 
+
+There should be some way of getting the current length of a string, since it
+could be used as the 'last' parameter in stridx, for getting the rest of a
+string starting at column n.  ST users have continually asked me about ways to
+get the current length of a string parameter (e.g., from within a CL script).
+
+One solution is to change the meaning of some of the parameter attributes for
+string parameters to something which makes more sense: 
+
+	p_length  --  contains the current string length, updated whenever
+		      the parameter is changed.
+	p_max     --  contains the maximum string length
+
+These would require changes primarily in param.c and gram.c.
+
+Also, currently trying an =param.p_min or p_max on a string parameter results 
+in an access violation.
