RE: Binding directory trouble

You really shouldn't have been binding M1 into each program that needs to use it.

Instead, M1 should have been in a service program, called for example MYSRVPGM.

MYSRVPGM could have been in an application specific or company wide binding directory that most if not
all programs made use of. Only *SRVPGM objects are listed in this binding directory.

When you created M2, it could have gone into MYSRVPGM or perhaps some other or a new service program.
You might at some point decide to create a binding directory to make it easier to recreate MYSRVPGM,
on the *MODULE objects to be included in MYSRVPGM should be listed in the binding directory. Note
that using the UPDSRVPGM command is easier than recreating the service program when one of its modules
change.

This way, when you change M1 or M2, none of the programs using the procedures in either need to be
recompiled.

The golden rule, if you have code you intend to share, the code belongs in a service program.

At this point you have two choices:
1) Create your service program(s) and use it only for your program right now.
2) Create your service program(s) and change all programs containing M1 to use the service program(s).

Option one is less work up front. If it were me, I'd rename M1 to M1A. That way if you changed any
current programs containing M1 they wouldn't be able to find M1 and you'd be force to update the
programs to use the service program(s).

Lastly, before starting to use service programs, make sure you understand and use BINDER SOURCE.
Binder source is the key to allowing modules to be changed in a service program without recompiling
the programs that use the service program. There should be plenty of information online and in the
archives about BINDER SOURCE, and you can of course ask questions here.

Hi

I just added a simple CALLP to a module M1. The procedure
called is in module M2 so I added the module M2 to my
program's binding directory.
No problem.

Now, what about all the other programmes that bind in M1.
They need M2 as well in their BNDDIR. But M2 calls other
procedures from other modules that call other procedures
from other modules that call .....

Just my luck, M1 is used just about everywhere and the boss
can't understand why suddenly he can't compile his own
program anymore!

Even worse we have a rule that makes us recompile every
program that uses a module when that module is modified. I
called our utility program with M1 as its input parameter. It
looks like it wants to compile every program in the shop.

What do I do folks?
