RE: Procedure Management Procedures

["Jim Langston" <jlangston@xxxxxxxxxxx>]

Hmm... you know, I wonder if that's not what I did.

I forgot about binding directories.

Thinking about it, yeah, I think I had 2 service programs,
the General with DATETIME and SYSTEM and then I had CARTAGE
with the CARTAGE module.

Then I created 2 different binding directories, CARTAGE and
GENERAL, cartage contained both service programs, and GENERAL
contained GENERAL.

I forgot about that 3rd level.

Jim, I don't think that's the best way to do it.  That way, you
have the same code in two places which is the very problem that
service programs are supposed to alleviate.

A better way to do it would be to have the CARTAGE service program
only have the cartage-specific modules.  You could have two binding
directories, if you wanted to ensure that only Cartage programs
used the CARTAGE service program.  In your CARTAGE binding directory,
put both service programs.  In your GENERAL binding directory, just
put the GENERAL service program.

(It's ok to have the same service program in more than one binding
directory, because a binding directory is just a list that's only
used at compile time.)
