Why can only 256 bytes be moved from one address to another
in a MVC?
Answer Posted / hariconda
MVC FORMAT: SS1 format
ASSEMBLER: OPCODE D1(L,B1),D2(B2)
here the length field is 8 bits or 1 byte so the maximum
value we can move is 256 bytes.
to move more than this use MVCL instruction

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?
