assembler maintains a table where Entry address for all lables being declared in the program. In below, symbol table will have details like "Para-1 000A", "VAR-1 ----" and so on. Address(entry point) for MVC instruction will not have its entry in symbol tabel as it does not have any label to be referred.. Still Location counter used to maintain address for each instruction. Here Location counter will have address of MVC as '000A' and its length of instruction. Here Para-1 address and MVC address is same as 0H does not reserve storage.
For example, Para-1 address is at X'000A'.
para-1 DS 0H
MVC VAR-1,VAR-2

VAR-1 CL4
VAR-2 CL4

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?
