In reply to my recent question about Fortran bindings for X-Windows I
got the following replies, not a hopeful list but better than nothing.
Thanks to all who responded.

 I can't believe i would actually suggest this..  but you might try
DECWindows. it seems like there is a fortran 77 binding library and
header files, or at least that's what i recall before i purged it off this
decstation.  i don't know if there is another good source for the
binding... perhaps if you find it, you might post?

f77v1.3 came with xview bindings for OpenWindows 1.0.

Being a `scientific programmer' doesn't excuse you from learning C, but 
that's not the point.  I have the User's Guide for Sun Fortran 1.3 (
although I don't yet have fortran 1.3),  in the back of this manual there is a
ten page appendix describing a fortran interface for XView.  There are
header files, and an intermediate library that converts fortran calls to C
calls.
I'm not sure whether this library comes with X11r4, OpenWindows, or
Fortran.

I really haven't used fortran with X11.
Some vendors (like Apollo, Dec and Ardent(I think)) provide what is called
fortran bindings for X11. If your system (like suns) don't have it
then you would have to create the binding yourself. The binding is written in
C.  An example can be found in the XGKS package on the apollos, in
/usr/um/xgks/src/fortran.
Suppose you want to use the X11 call XDrawString . You would write a
little piece of C code, say, myXDrawString_ that would call XDrawString. The
problem is all those arguments that the X routines need. 
I believe if you look in the code in
/usr/um/xgks/src/fortran you will get the idea. It is not an easy
task. The best thing is to use a vendors implementation of X11 fortran
bindings, if available, or a package (in this case XGKS) 
that has fortran bindings.
As far as I know, MIT X11 release doesn't have fortran bindings.
To get a better answer you could pose your question to the usenet
newsgroup
comp.windows.x .

Sorry I can't be more helpful.

My Fortran v1.3 manual has Appendix C "XView Toolkit" which talks
about the Fortran interface to the XView toolkit (which of course
is really written in C).  I haven't done it but it seems straight
forward.

Same here!

Hope this helps,

I don't think there is a FORTRAN binding for XLib or Xt, and I don't
think anyone plans to come up with one.  What you should probably be looking
at is GKS (if 2D is good enough) or PHIGS (if you need all the baggage in
it).  We at ATC sell GRAFPAK-GKS, with X-Window system support.  If you are
interested, please send me mail or contact our Sales Dept at
(714)-583-9119.
GKS and its FORTRAN binding are an ANSI standard.
