Any "command" name that you wish to call from the IDL
command line or from another procedure or function should
be in a file of the same name as the command in the IDL "path".
If there are multiple procedures and functions in the file,
then the procedure or function that has the same name as the file
should be the LAST procedure or function in the file.

If a procedure or function is in a file, but it does NOT
have the same name as the file, then you can generally assume
this is a utility routine for the procedure or function that
*does* have the same name as the file. That is to say, no one
plans to use that "command" outside of this file. If it were
found to be more useful than just a utility routine, it would
be yanked out of that file and put in another file that
was named appropriately.

In this way, you NEVER have to worry about things being
compiled when they are needed.

Have you thought about a good book about IDL? :-)

Cheers,
