RE: ILE question : parmameters, modules and service programs

We do not have a single service program. Instead, we use an
ordinary module containing all the exported procedures. I
understand that means the code is duplicated by each program
that uses the module. My question is, so what? What are we missing.

Making a change in a procedure requires you to recompile 100's of programs that
use that module.

If you had the procedure in a service program, you'd only recompile the one
service program.

Another problem is when we need to add a parameter to an
exported procedure. In RPGIII. How do we do this when the
procedure is called from a hundred others?

Since you can't have procedures in RPG III, I'll assume you meant RPG IV.

Simple, you add the parameter with OPTIONS(*NOPASS).

Means extra code in the procedure to deal with the fact that a parameter may
not be passed. But
that'd much easier than dealing with 100's of programs that call that procedure.
