Re: Processes after CRTSRVPGM

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

Yes, you are right. Mistakes happen, and yes using EXPORT(*ALL) and re-compiling all consuming programs will avoid this mistake. I've never deleted a sub-procedure once it's gone into production, and so I've never had this come up. Thanks!
