Answer / albert n
You will need to open de file SYSIN via a DCB and read the
data via GET commands. The data in the PARM field is passed
via register 1. Any dataset you want to use in Assembler
you will need to open. There are no automatic allocation.

In jcl
//SYSIN DD *
A
B
C
it will receive in assmbler code thru R01(it contain the
address of data) first 2 byte contain the length of data
and actual data will be stored from 3rd byte.

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?
