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.

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.
