Re: procedures vs subprocedures

From any non-RPG point of view, a procedure and a subprocedure are the same
thing - something that can be called with a bound call.  From an RPG point
of view, there are two kinds of procedures: main procedures, and
subprocedures.
Main procedures have a cycle and are coded like an RPG program; they can be
program-entry-procedures.  Subprocedures don't have a cycle, are coded with
P
specs and can't be program-entry-procedures.

For those who know C: an RPG main procedure is not exactly the same notion
as
a C main procedure.  C can only have one main procedure per program; it's
always
called 'main'.  RPG can have one main procedure per module, and its name is
the same as the name of the module that was created.
