RE: Processes after CRTSRVPGM

["Murphy, Mark" <MurphyM@xxxxxxxxxx>]

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!
