Re: A question about multi-module SRVPGM

Hi, John:

If you have a *MODULE that contains one or more procedures that are used 
in only one bound ILE *PGM, then it probably "makes sense" to just bind 
that *MODULE directly into that *PGM (bind by copy).

If two or more ILE *PGMs use any of the procedures in that *MODULE, then 
it probably "makes sense" to create a *SRVPGM, and add that *SRVPGM to a 
binding directory (*BNDDIR) and use that binding directory when you 
create the ILE *PGMs, so those *PGMs will "bind by reference" to any 
needed *SRVPGMs.

This is a "good thing" from a maintenance point of view, because, when 
you eventually have to modify that *MODULE (to fix a problem or add new 
features), you need only recreate the one place where it is bound -- 
either a single ILE *PGM or a single *SRVPGM.  You can even do this 
using UPDPGM or UPDSRVPGM.

Does that help?
