In MVC arrangement, the M, V, and C are typically executable objects. I
never see M, V, and C as modules. One of the main purpose of MVC is to
allow single point business logic (the M). I'm not understanding the
concept of creating them as module. Even if you want to do it as
module, what is the different between making them a *SRVPGM vs *MODULE
or just make them become one single *module if you know that no other
program will ever need to bind each individual *module?

How about the classic MVC arrangement?
o Module for screen handling
o Module for control flow
o Module for data access

The data access module will likely call functions in a service program

to perform the real work but this approach (if done properly allows
you plug in a different screen handler (e.g., CGI) or different
database access. None of these modules would be common to other
programs but by using separate modules I gain more flexibility at the

cost of a slight increase in complexity.
