Can we use an equated value as operand for an MVC
instruction? Reason for the same
Answer Posted / deepu
Answer 4 is correct. Yes...An equate in MVC will not give
any compilation errors if the decimal equvalent of the
eqaute is less than 4096,the compilation of the code will
go fine.But the program execution will give S0C abends, as
the program will try to access from protected memory
area.

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?
