RE: Processes after CRTSRVPGM

Not sure I understand your question. My example is merely to show the
danger of using *prv. In this example, I just try to demonstrate that
if developer forgot to recompile an existing program that was compiled
before the *current was added, this program will not get signature
violation. At run time it will actually execute IFS_Proc3 even though
the statement is coded to execute IFS_Proc2. This is where I don't
think *prv should be used (Again personal preference only). It does not
give you any protection and actually given developer some false sense of
security.

Explain to me why I would expect any program to be able to call a
procedure that I have removed from the service program. If you use a
tool incorrectly you are bound to have trouble.

If you binding language looks like below, guess what will happen if you
forgot/miss recompile an existing program that is still using one of the
*prv signature? This existing program will not get signature violation.
It just going to execute the wrong procedure when executing IFS_Proc2.

STRPGMEXP PGMLVL(*CURRENT)
EXPORT SYMBOL(IFS_Proc1)
EXPORT SYMBOL(IFS_Proc3)
ENDPGMEXP

STRPGMEXP PGMLVL(*PRV)
EXPORT SYMBOL(IFS_Proc1)
EXPORT SYMBOL(IFS_Proc2)
EXPORT SYMBOL(IFS_Proc3)
ENDPGMEXP

STRPGMEXP PGMLVL(*PRV)
EXPORT SYMBOL(IFS_Proc1)
EXPORT SYMBOL(IFS_Proc2)
ENDPGMEXP


STRPGMEXP PGMLVL(*PRV)
EXPORT SYMBOL(IFS_Proc1)
ENDPGMEXP

Can you write a little more on why you feel *PRV is dangerous? I've
used this exclusively since V3 and haven't encountered any problems...
I'm hoping I haven't missed something!
