AUTOGRAPH -- This directory contains the contents of the NCAR file
autograph.f, unpacked one subroutine per file. Here is the revision file
supplied by NCAR for the autograph package. For NOAO specific enhancements,
see gio$ncarutil/README.
Revision history:
February, 1979 Added a revision history and enhanced machine
independency.
September, 1979 Fixed a couple of problems which caused the code to
bomb when core was pre-set to indefinites and the
1st graph drawn was peculiar in some way and another
which caused it to set the default dashed-line-speci-
fier length wrong. Added new documentation.
October, 1979 Changed the way IDIOT behaves when NPTS is negative.
March, 1980 Fixed a couple of small errors, one which prevented
an error exit in AGSETP from ever being reached and
another which caused AUTOGRAPH to blow up when given
a zero or negative on a logarithmic axis. Changed
the way in which NBPF is computed by AGSTR1.
August, 1981 Removed all calls setting the plotter intensity and
made the computation of the variable SMRL portable.
April, 1984 Made the code strictly FORTRAN-77 compatible, taking
out all dependency on support routines (such as LOC).
This required some changes in the user interface.
February, 1985 Put code in AGSETP to reclaim character-store space
used by character-string dash patterns when they are
redefined using binary patterns. Also changed AGGTCH
to return a single blank for a non-existent string.
August, 1985 Put code in AGGETP so that the label-name identifier
is now returned properly. Among other things, this
cures a problem which caused the character-storage
space to be eaten up.
December, 1985 Fixed AGSETP to zero the current-line pointer when
the current-label pointer is changed.
January, 1986 Fixed AGAXIS to respond properly to the zeroing of
NCIM by AGCHNL.
