You are using the PRV and CURRENT technique. Your old program that has
not been rebound is looking at the PRV version of binder source so it will
call it just fine. The issue comes in when you are doing something like
this....
STRPGMEXP PGMLVL(*CURRENT) SIGNATURE('PNS338SP')
EXPORT SYMBOL(PROC1)
EXPORT SYMBOL(PROC2)
ENDPGMEXP
and then you change your binder source to this....
STRPGMEXP PGMLVL(*CURRENT) SIGNATURE('PNS338SP')
EXPORT SYMBOL(PROC1)
EXPORT SYMBOL(PROC3)
EXPORT SYMBOL(PROC2)
ENDPGMEXP
Notice that the signature is the same, so the bound programs will be
looking at this new export list and expect PROC2 to be the second symbol.
Then it will fail and call PROC3 instead. You haven't done anything wrong
yet, that's why its still working properly :D

Did you recompile "my program", the one calling P1 and P2?
If you did, then that's why it still called P2 as expected.
If you don't recompile "my program" and change the order of
the exported procedure in the binding language then you would
end up calling P3.
No, I haven't yet recompiled or rebound the programs.
Here's one binder source :
/* This is junkbndcur */
STRPGMEXP PGMLVL( *CURRENT ) SIGNATURE(*GEN)
EXPORT SYMBOL( "PROC1" )
EXPORT SYMBOL( "PROC3" )
EXPORT SYMBOL( "PROC2" )
ENDPGMEXP
STRPGMEXP PGMLVL( *PRV ) SIGNATURE(*GEN)
EXPORT SYMBOL( "PROC1" )
EXPORT SYMBOL( "PROC2" )
ENDPGMEXP
STRPGMEXP PGMLVL( *PRV ) SIGNATURE(*GEN)
EXPORT SYMBOL( "PROC1" )
ENDPGMEXP
If I look at SRVPGM junkbndcur, I see :
Signatures :
00000000000000000000F0E2C70D3D47
000000000000000000000F0E00437647
0000000000000000000000F1C3D6D9D7
In my program junkbndcur, I see :
Programme
de service Bibliothèque Activation Signature
JUNKSRVCUR *LIBL *IMMED 000000000000000000000F0E00437647
So you can see it is using the second version of the service program.
Looking at the binder source, I would expect it to use PROC2 when it
called PROC2, but call PROC3 instead of PROC2 if I recompile junkbndcur.
