You can also use environment variables, if appropriate.

You can't pass it directly into the program in the way
you are trying to do it. Rather, you have to use a
-arg command line switch on the IDL command you are using
and pass it that way.
Inside your program, you can recover the command line argument
(or arguments) using the function COMMAND_LINE_ARGS.
See the on-line help for "command line switches" for details.
Cheers,
David
