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?
What is symbol table in assembler?
Is it possible to access some memory location (Ex: VAR1 DS P) without using Base Displacement?
about maximum displacement and how to cross this limit.
registers(0-15) ,where they are going be resides., does that mean here is it resides whether real or virtual memory? and why? then why we are assign even registers(0 to 6) for FP operations????
What is maximum displacement?
what is need of START 0?. In steed of '0' can we use any other numerics?. if we use what will happen?.
