Re: How to Find what module a procedure is located in

Hi, Alan:

Personally, I would take it one step further, and suggest requiring
naming all procedures with a "prefix" of the MODULE name (for modules
that are bound into a single program), or the target SRVPGM name. So,
for example, you might have the following procedures:

PERSONNEL_Add_Employee
PERSONNEL_Remove_Employee
PERSONNEL_Update_Employee_Details

and so on, whether implemented as one *MODULE or several, bound into a
*SRVPGM named "PERSONNEL".

With this type of "naming convention" there is no need for tools or
searching -- you know right away from the name where it is found.

What do you think?

Thanks,

Mark S. Waterbury

I see this going on all over the place and it is the biggest No, No I can
think of. Putting the same module into multiple programs or service
programs is a disaster. I routinely bind a CLLE driver to a RPGLE module
and many casees RPGLE to CLLE to perform specific functions I want to
perform but they have the same naming.

The other big No, No I keep see is people naming modules with a different
name for each module.

I use a system like

XVERRH Top Level
XVERRH_PR
XVERRH_B
XVERRH_M01
XVERRH_M02
XVERRH_M03

but I keep seeing stuff like

DS8924RP - Module One
DS8925RP - Module Two
DS8926RP - Module three

Bound up to make say DS8927RP or something like it. What is bundled with
wha?. What a nightmare.

Your example below does not violate my suggestion, of binding a given
*MODULE into one place (a single *PGM or *SRVPGM). I said nothing about
any given *PGM or *SRVPGM being composed of one or more *MODULEs. =-O

Let;s say your CLLE *MODULE is named CLLE1, and your RPGLE *MODULE is
named RPGLE1 ... what I am saying is that you should almost never "bind
by copy" either one of those two modules into more than one *PGM or
*SRVPGM. I did not say that you should avoid binding both of them
together into a single *PGM or *SRVPGM.

The issue I was speaking to is "maintenance" -- if you bind the same
*MODULE into many *PGMs and/or multiple *SRVPGMs, then any time you have
to "fix" code in that *MODULE, you must "hunt down" every place it is
bound into, and replace it, either using UPDPGM or UPDSRVPGM, or using
CRTPGM or CRTSRVPGM to recreate from all of the component *MODULEs
(assuming you keep them around.)

Hope that helps,

I've heard this recommendation a couple times in these threads. It seems
to go against one of the principle "benefits" of ILE - that one can
combine modules in different languages.

One question is, how much benefit IS that? I find at least one situation
to be beneficial, as described here -

We often have a front-end CL that sets up the environment, then calls an
RPG program to do the work.

I think it's a good idea to change the call to a CALLPRC, make the RPG
into a module, same with the CL, and link the 2 together - one program
object instead of two, for what it's worth.

Now that adds its own complexity to things, in my experience. Here is
where a change management app is helpful.

To add to the idea, the RPG module can have multiple procedures, and the
CL can call them as needed - instead of calling several separate
programs, again reducing the number of program objects.

Just an idea - that a CL driver program can make calls into a linked
module instead of separate programs.

FWIW

Maintenance will be easier if you avoid binding *MODULEs into more than
one place (one *PGM or one *SRVPGM only).
