My solution to this is not to create a library *file* (like NukMed.pro) with all the
goodies but a library *directory* (like ~/pvandelst/idl/NukMed) which contains all the
_separate_ files. The directory, which is beneath the idl directory, is then automagically
added to my IDL_PATH environment variable because I do a: export
IDL_PATH=$IDL_PATH:+\${HOME}/idl
Anything below ${HOME}/idl is tacked on the end of the path.

Has it really to be the LAST program module ? I think it is working also
with other "places" in the file. Or will the module only find functions in
freont of him in the file?

If you find you have to "compile" the code before
you can use it, then the code is not written correctly.
Putting it in the lib directory won't help, alas. :-(
If code is written so that the *last* program module in
the file has the same name as the program file, which will
also be the "name" of the command you are trying to build,
then this program will be automatically compiled when
the "command" is used, assuming the file is anywhere
in the !PATH.
You never have to pre-compile anything in IDL, assuming you
have written it correctly.
Cheers,
David

I have never understood the reason(s) for this, and find it somewhat
inconvenient. If I have (say) a procedure and a few related functions
that I would logically keep in the same file, it also seems logical to
me to put the "main" procedure (the one whose name matches the
filename) at the beginning of the file, rather than burying it at then
end. Why doesn't IDL simply compile everything in a file? What value
does the user get from stopping the compilation part of the way through
a file? (Aside from confusing newbies, of course, which has, at least,
mild entertainment value.)
