This is a followup to an earlier announcement made several months ago
regarding a graphics library that included functions for the GPX.  I've
recently added another program to our molecular modeling software system
that allows the user to sketch 2-D structures on a GPX display window.

As this is not something that I would (ever?) want to do on a  Tek 4105,
it does not use the graphics library mentioned in the previous posting.
Rather, it uses a collection of UIS$ routines in their full glory to get
the job done.  Yes, the code is written in Fortran under VMS, but several
of the DEC extensions are REQUIRED (such as structure/record) to make it
fly.

I think this code would be useful as a prototype for GPX development (if there
IS such a thing), as it opens several windows, plays with menus and tries
to be clever with several AST's.  If anybody is interested, please get in
touch and I'll email you a copy (~900 lines).  If anybody reading this is
actively DOING GPX development, please let me know (so I don't have to
reinvent quite so many wheels...).
