I have no experience with Windows NT, but the last time I used IDL for Windows,
I was able to use routine names longer than eight characters, so long as they
were stored in files whose names used the first eight characters of the routine
name. Thus, if I had a routine named COMBINE_COLORS, IDL would be able to find
it so long as it was stored in a file called COMBINE_.PRO somewhere in !PATH.
Also, if I had a routine called COMBINE_VEL, then it would also have to be in
that same file for IDL to find it. Probably, IDL for Windows NT acts the same
way.
Similarly, if I wish to open a file, I can open it with a filename longer than
eight characters, and only the first eight will be paid attention to.
Hence, I agree with the statement that the filenames have to be converted to
the 8.3 convention, but I disagree with the statement that all references to
these files need to follow that convention. You don't have to rename your
procedures. This is a common misconception about IDL for Windows.
