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.
Does anyone know if this is a documented behavior? I haven't found a definitive answer.
Thanks.
