RE: CALL, CALLP, & CALLB

["Stone, Brad V (PP)" <bvstone@xxxxxxxxxxxxx>]

Patrick,

I never bind by copy, but the documentation for each method should be
similar.

My documentation is the /COPY line in the final program.  I name all of my
modules F.xxxxx and my /COPY members P.xxxxx.  So, if in a program I see:

/COPY QBNDSRC/P.String

I know that the F.String Module is being used in that program.

One thing you must remember is that changes to modules can be made.  If you
are binding by reference and don't change the export of the subprocedures
(ie add or removed exported subprocedures) and only change the underlying
code, recreating the service program is all that is needed in most cases.

If you DO add or remove subprocedures, this will change the signature of the
service program.  But if you use Binder Language you can specify *PRV for a
list of subprocedures that you are exporting and retain the original
signature as well as creating a new signature.  (See the ILE reference
manual for some pretty good examples)  (EXPORT *ALL is a no-no in my book).

Hello, everyone.

The only remaining question I have on the CALLB/CALLP is how folks are
documenting the modules that are bound by copy so that when a sub-program
is changed, how do you keep track of which programs to update across your
system? It is obvious that you should not bind a program that changes
frequently, but occasionally changes to occur to bound modules.

Hans, I will look into the CALLP for all my long distance calling needs.
Thanks for the great explanation. I have begun using the CALLB, but will
quickly switch to the CALLP.

Thanks to everyone for the helpful advice. The manuals are helpful for the
"hows", but this discussion group is so much better for the "whys". Manuals
are great for command syntax, but the continued support and ideas generated
from the question/answer posts on this forem is immeasurable. Too bad
manuals don't have a natural language query system built in, eh?
