FORWARD_FUNCTION is not the best, but I do find it useful in some
special cases, like when there is an IDL version dependency.  It's a
little bit of insurance that I stick at the top of my program file to
give more precise behavior.

But I do see what you are saying here: pre-5.3 IDL STRPOS functions
don't take keywords.  Then your only alternative is to use
call_function as suggested.
