And possibly misleading, as well. :-)

The capitalization of the procedure or function is
entirely irrelevant. IDL is case insensitive. The
name of the file should be spelled with lowercase
letters if you expect IDL to find it automatically
(as you should). If you always compile your procedures
and functions before you use them, then (really!) you
should be using another language than IDL, as there is
ABSOLUTELY no reason to do this.

You should even name your Windows files with lowercase
letters, IMHO, since you never know when you might find
yourself loaning them to someone with a machine different
from yours. This can cause an enormous amount of heartache
before you figure out what the problem is.
