I'm pretty sure it uses PATH to determine the location of the
program.
Try checking your PATH carefully to make sure that you haven't added
it incorrectly. If you can run "myprog" from the command line you
should be able to run it from within IDL.
What do you get if you run :
IDL> spawn,'echo $PATH'

What shell are you using?
I notice that in the subject you mention setenv which implies you
are using csh/tcsh. AFIAK spawn will use sh so there may be some
difference between the path you set in csh/tcsh and the path used
by sh.
Are you actually setting and exporting PATH?

That's what I thought, too. Before I started IDL, I verified that
I could run "myprog" from any directory as a result of extending
the path correctly. But subsequently, I'm not able to SPAWN the
program from within IDL without indicating its exact location.

I get the UNIX pathname BEFORE I extended the path. Not only that,
but if I try to extend the PATH environment variable from within
IDL, I still can't run "myprog". Boy, am I confused!
