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.

if i have three programs progA,progB and progC .now i call progB from progA. but the progB does not exist . now i want to call progC instead of starting dump. how can we achieve this.

RPG/400 number of Records present in a physical file using file information data structure FPF001 IP E DISK F KINFDS INFDS1 IINFDS1 DS I *RECORD RECORD Is this coding correct sir,i have given I P E that is I- input,P-primary file,E-externally described. Primary to use RPG logic cycle,is this the correct method because we have to find number of records present using file information data structure in RPG/400 without doing any input/output operations on the file and also without using DSPFD,SQL. If the above coding is correct means,when i compile the program it gets compiled,but if i call the program it does not return anything,i need number of records,please complete the coding sir.
