RE: Prototype in RPG/ILE

["Goodbar, Loyd (AFS-Water Valley)" <LGoodbar@xxxxxxxxxxxxxx>]

I'm heading down that path also.

In short, the prototype ensures there is a consistent way to use the
procedure. It allows the compiler to check all the calls to the procedure,
and ensure the number and type of parameters are correct. 

Now, Instead of generating a run-time error on a misformed call, you get a
compiler error that you can fix before the program is put into production.

Using prototypes is not required (I guess) but strongly recommended.

HTH,
Loyd
