I have not figured out what caused the crash. As I say,
the two files are nearly identical. I have sent the file
to some folks at ITTVIS. I'd rather get back to doing
something more useful than twiddling my thumbs while my
computer re-boots. :-)

Have you figured out why this causes a crash rather than an error or some other within-the-bounds-of-normal odd behaviour? Are you still getting other crashes from 8.1? Perhaps you could give ITTVIS your special version of tex2idl - it might help to trace the problem.
cheers,
Greg

It's taken 20 years or so, but name space collisions
are really becoming a problem. It would probably be
less so if ITTVIS would stop writing all their new
software in IDL and go back to writing it in C. ;-)

Just to finish this off, so I can go get some real
work done, I still don't know where the tex2idl.pro
I had in my path came from. I have diffed it with
the tex2idl.pro in both the IDL 8.0.1 and IDL 8.1
directories and the only *apparent* difference is that
a number of FOREACH loops are commented out in the
problem file and replaced by FOR loops. To an
untrained eye it looks as though they do identical
things.
In any case, I would guess that the version I had
was written sometime before the FOREACH language
structure was working properly. (Maybe this was
from the IDL 8 beta. That's possible!)
Cheers,
David

I think what happened was, at some time in the past I
was trying to figure out how this tex2idl file worked.
I can't edit and save an ITTVIS-supplied file in the
normal IDL directories because I am not the "creator"
of the file in Windows 7. So, if I want to play with
these files, I need to save them somewhere else. I
normally save them in a "junk" directory that is not
on my path. Somehow, I accidentally saved this file
(I think!) in my CoyotePlus directory, which was on
my IDL path.
So, I *think* this must have been the tex2idl file
that came with IDL 8.0.1, but I haven't checked to
be sure.
Cheers,
David

Well, now I see that the *original* is named texToIDL,
not tex2idl. So I don't really know where this file came
from or if I was even using it.
All I know is that this was a hell of a hard problem to
track down! :-(
