Another GREAT reason to use procedures instead of sub-routines is the
reusability factor.

Traditionally, subroutines were used for "repeatable" code blocks and
often, these blocks of cose were common to more than one program. Although
it was always possible to code them in /COPY elements, this was not often
done as it was confusing to most programmers.

With procedures, the code element exists only once and, as Steven stated
earlier, it is quite easy to see which variables are passed.

One could go on and on about the benefits, but as Steven also succinctly
put,

Procedures are Cool.

To the programmer, there's not a lot of difference in using a procedure vs
a
subroutine.  What I'm trying to say is that you can usually achieve the
same
results whether you put your code in a procedure OR a subroutine, BUT:

1) It is easier to see what values the procedure is expecting via the
arguments being passed (tight coupling, which is good)...whereas using the
traditional RPG subroutine it is not always immediately clear which fields
in the program that the subroutine is using and/or possibly modifying
(loose
coupling, which is NOT good).

2) Procedures are Cool!

why do we use procedures only in modules in ILE programs?why nt
subroutines?whats the diff ...plz kindly answer me
Best regards
