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!
