RE: Overloading in RPG.

You know, good point.

I was doing what some others talked about - passing something that would
tell the subprocedure what to do.  I didn't even think of simply defining
three (or whatever) different subprocedures.  Now that you mention it,
you're right - I'd have to do it anyway!  So I just did it on a report
program that I'm working on.  It makes the code easier to read (and
maintain) because I eliminated selects and if statements.  If something
needed to be added to one of the procedures, you don't need to worry about
creating problems in the other procedures.

I am very glad that you posted!

Thanks,

Phil

I still don't see any benefit to overloading. It seems like an opportunity
for confusion.

I don't see how you have simplified maintenance any. You still have 4
subprograms to maintain.

In addition, I don't see how there would be any guarantee that these
routines would do the same thing, just because they have the same name. As I
understand it, they are entirely different.

I would prefer to have one procedure and do any necessary conversion in the
program.

For example:

        DDaysDur          PR             5I 0
             D CharDate1                      8A
             D CharDate2                      8A

        C                   Eval      Cdate1 = Ndate1
        C                   Eval      Days = DaysDur(Cdate1: Cdate2)
