According to the RPG Reference manual, there are basically two types 
of procedures:

1) The "main procedure" is what you normally think of as a program. 
That is, it's that procedure that runs the RPG logic cycle.

2) A "subprocedure" is a procedure that's not a main procedure. (A 
NOMAIN module only contains subprocedures.)

Otherwise, in practice, the terms "procedure" and "subprocedure" are 
pretty much synonymous. "Procedure" is just the more general term.
