When you have a program (or service program and use updsrvpgm) where you
have changed a module in the program, you can use the UPD commands to
rebuild the program and not have to recreate it.

unnecessarilyrecompiling programs that call service programs

Again, thanks to everyone offering advice and answers! I'd definitely
be lost
without the midrange.com lists! As someone mentioned elsewhere
recently, you don't know what you don't know. I'm reading through the
Concepts reference and Brad's "Implementing ILE for RPG 101".

What are the circumstances by which one needs to use UPDPGM? I
presume that it replaces the CRT* compile to a client program to which
modifications were made to its source?

Let me just clear it. The calls are made by vector number - not by
name. So each call to your procedures are stored as an index to an
array of procedure pointers. If you introduce a new procedure in
between existing procedures, then subsequent procedures are "moved"
one index higher- messing up the refereces in the "client"
calls..... does it
make sense?

UPDPGM of all client programs will ultimately fix this if you want
keep the procedure names in a certain order.

If you put it in the end of the binder source - you have no
to recompile... imho. That is best practice.
