In the house keeping section of an MVS assembly language program, like the one below
STM R14,R12,12(R13)
BASR R12,R0
USING *,R12,R11
LA R11,2048
LA R11,2048(R11,R12)
....
....
1. What if BASR R12,R0 IS NOT PRECEDE USING *,R12,R11?
2. USING (base address), REGISTER
does USING directive says assembler to treat particular Register as a base register with the mentioned base address..in the above case * i.e current location counter..well if that is the case why we need BASR R12,R0 ?
3. What if I write like
STM R14,R12,12(R13)
BASR R12,R0
LA R11,2048
LA R11,2048(R11,R12)
USING *,R12,R11
there is no address resolution being calculated in both LA statements so is it a right way to set Base register?..will there be any issues with Domain regarding R11 and R12?
