I just stumbled onto something today. Apparently an UPDSRVPGM does not

any files used.

I changed the format of a file (added a field) and recompiled all

using it. For the service program using this file I recompiled the

module,

then did UPDSRVPGM. The service program record format ID does not match
the file record format ID.

This is also sadly true of UPGPGM and has been this way forever. It is, I
suspect, why most (all?) change management tools tend to rebuild everything
when a file layout changes rather than rebuild affected modules and using
UPDxxx

I've always been surprised that CM vendors (among others) have not used
their influence with IBM to get this changed. I guess the fact that it
hasn't changed may be because of a problem with the underlying ILE
architecture. e.g. The object does not know which module uses which file
object and therefore can't delete obsolete references. If that were the
case you'd think a single module PGM or SRVPGM would not exhibit this
behaviour since the redundancy can be easily determined but ...
