If you have a program *PGM made up of multiple modules, ie. you're using
"bind by copy" as opposed of the recommended "bind by reference" (to a

Then if you change the source for one module, you can use UPDPGM to get the
updated code into the *PGM.

UPDSRVPGM works the same way for a *SRVPGM made up of multiple modules.

recently, you don't know what you don't know. I'm reading through the ILE
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 no
modifications were made to its source?

Let me just clear it. The calls are made by vector number - not by name.
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" to 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 to
the procedure names in a certain order.

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