RE: Interfaces for RPG (was RPGV?)

One thing on my wishlist are interfaces for RPG.

It could be something like this:

Create a copybook with some prototypes.
Add a keyword to your module which interface it tries to implement (reference to that copybook).
Let the compiler check if all procedure prototypes are implemented.
Use reflection to get a procedure pointer on the procedure.

ATM I can do this but without the compiler checking for the implementation. It would be nice if I could be sure that certain procedures are really implemented by a module at compile time (also with the correct parameters and return value, not just the name).

My 2 cents.

Using subprocedures - in fact, this might be better justification for
making everything free.

Why do you have more than a single /FREE at the start of your C-Specs?
What are you doing that requires you to drop in and out of free-form?
