Re: Quick question (and I think it's come up before)

The key idea is this: missing parms are ok in a program, unless you try to use them. It is only the use of them that causes the problems. So, if your program doesn't use the missing parm, you are golden. Anyway that you solve that issue is fine.
My own preference is to use an externally defined data structure for the parm, and have just one parm. Then, missing data is no problem (as long as you initialize numeric fields).

What I meant was optional parameters to the program itself. Not to a prototyped procedure call within it.
Certainly an easy enough thing to do with MI or C. But I don't recall whether or not it's doable in RPG.
I've already figured out another way of doing what's needed, and I'm going to run an experiment to see what happens if you call a program with fewer parameters than specified, but I'm still curious. Perhaps morbidly so.
