Dave:

In this article, Barbara Morris explains why MONMSG CPF3601 is not a reliable way to detect "missing" (*NOPASS) parameters in ILE CL::

Hope that helps,

I have a couple of processes where I'd like to have one or two optional
parms.
In the past, I've just tried using them in a CHGVAR and monitor for
MCH3601.
But... I'm wondering if %address() can be used instead. I think it
would be cleaner. In my testing, I've seen hex zeros for the %
address of a non-passed parm. That seems to indicate a *NULL will
be returned. Since it's consistent and not a garbage address, I
would think I could count on that logoc.
As hinted at but may not have been made completely clear, %ADDR()
will work in *OMIT situations but will not work in *NOPASS situations. I'm
very content with depending upon MONMSG but since CLLE doesn't have a
built-in function for %PARMS() then others probably prefer to call the LE
routines.

Sincerely,

Dave Clark
