How are data passed from jcl parm to assembler program?

Question Posted / rajeev saini


How are data passed from jcl parm to assembler program?..

Answer / Subhash Bhatt

Data can be passed from JCL parameters to an assembler program using either the DSNAME or DD DISPLACEMENT method. In the DSNAME method, the parameter name is referenced directly in the assembler code, while in the DD DISPLACEMENT method, a specific offset within a data set is used.

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?
