Answer Posted / saurabh biswas
Both the operands of a MVC operand is a storage operand.
But the equated value is an immediate data not a storage
operand. So if you use equated value in a MVC instruction
it will try to resolve the equated value in the form of
BDDD format. It will not cause any any error at compilation
time but will cause an unpredictable result at run time.

how to pass the parameters from jcl to assembler pgm?
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?
