Oh, dear. *What* programs!?
I was once teaching an IDL course and one
of the people attending said to me, "IDL is
kind of strange isn't it? It never gives you
any error messages."
Say what!? About an hour later I learned that
this guy had gotten an IDL startup file from
one of his "friends" and that !Quiet was set
to 1. Do you realize how hard it is to program
something without error messages!
The bottom line is this: one of your "friends" may
have a weird sense of humor.
I would do this. Start IDL without any start-up files,
and without running any of the code you got from friends.
Then try this:
IDL> Surface, dist(15)
If that doesn't work, tell us more about what
version of IDL you are running, whether you
installed it yourself, whether you had any
problems during install, etc.
I think you have either set some system variables
inadvertently, or your installation is not set up
properly. Did you change the name of the main IDL
directory?
Cheers,
David
