How we can Pass the parameters from JCL to assembler Pgm?

Answer Posted / divya

R1 contains a fullword that contains a address pointing to
tyhe parm data. In pgm before accessing the parm data use L
Rn,0(,R1) where n=3,..11 , Rn contains the address that
points to parm data. Create DSECT that contains a halfword
and the length of the data.

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?
