Joel, just to clarify, it's ok to use VALUE and options(*nopass)
together as long as you make sure the parameter was passed before using
it.  But with CONST, you shouldn't refer to the parameter if it wasn't
passed, either.  So I don't think there's any reason not to use VALUE
and OPTIONS(*NOPASS).

(The dangerous thing you were doing was using the unpassed parameter as
though it was a local variable.)
