There is an area of IDL memory set aside to compile IDL
programs. This is the "program code area" (I think). In
any case, you usually see this error message when you are
working with really poorly written code (usually a colleague's). :-)

Actually, you usually see it when you are working with huge
IDL main-level programs, rather than the more normal procedures
and functions. The work-around, of course, is to write procedures
and functions like you are suppose to and get away from
huge journal-type scripts.

I'm not surprised things work better when you compile
the mail-level program and then run it with .GO. The
compiler probably can re-size the program code area
dynamically.

And, by the way, that "RUN" button on the IDLDE probably
confuses more people than helps. I truly don't know
what it can be used for, other than to run IDL procedures
that don't require any arguments. I usually point people
away from it.

Cheers,

David
