Answer / paras

A module is a non executable program and it contains one or
more procedures. If you have modules without procedure then
it means that it is having only one default procedure and
in case we can use CALLB. But if a module is having more
than one procedure then we can give explicitly the
procedure name to be called in case of CALLP
Out of these three Callp is the most efficient one.

WE COMPILE A MODULE BUT WE RUN A PROCEDURE.

Answer / svankipu

A module is a non-runnable entity and it contains 1 or
more procedures. If there's no procedure in the module, then
it means it has only one default procedure with the same
name as that of Module.

Any way one needs to compile the module with
opt-15(CRTRPGMOD) & then compile the program, binding the
module created above with the program using opt-14(CRTPGM).

Only then you can execute/run the program-object, which has
the behavior defined in the above created procedure.

But as such both procedures and modules are non-runnable
piece of code.(& ofcourse u have a object-type for
Module(*MOD), whereas there's no even object for procedure.

Answer / lama

Module is a object ( output of compiler) which is non runable.

Procedure is a set of language statements which perform
certain action and return to the calling program . we
genrally store procedure into copybook programs.
