RE: Examine Parms in a Loop

All %parmNum() does is convert the name to number at compile time. You could just do:
If %parms() >= 2;



Not saying that's a good thing to do though...

Subject: Examine Parms in a Loop

In RPG, I'm familiar with %addr, %parms, and %parmnum for testing parameters to make sure they were passed to the program or procedure and have a valid address. For example:

if %parms < %parmnum(pMyData) // if parm not passed
or %addr(pMyData) = *null; // or was omitted
else; // skip it, else
// do something
endif;

But I have a large number of parameters that I would like to be able to examine in a loop -- rather than have to code each test individually and repeatedly. Is there a way I can check the address of a parameter by its parm number rather than by its parm name? Thanks.

Sincerely,

Dave Clark
