Answer / ajay kuriyal
from my point of view the best way is to do boolean
XR RX,RX
Now RX will have '0000'

Answer / pazhanivel seethapathy
The standard ways to intialize registers are as follows
1. SR Rx,Rx or
2. LA Rx,0 or
3. XR Rx,Rx

Answer / sunny
XR Rx,Rx
This is the best way and most efficient way of initializing
the register values or Label values to '0'.
Its because the time required to execute a Logical
Instruction is always less than the Arithmetic Instructions.
e.g SR Rx,Rx consumes more execution time than XR Rx,Rx.
So XR Rx,Rx is a better way to do obtain our target.

Answer / sourav
The best way to initialize a register is
SR Rx,Rx
instruction.
There are other ways as well, few of them are already
posted.

Answer / anonym
1. Register i-memory (fastest)
LA x,0
SRL x,64
2. register register
XGR/XR x,x
SGR/SR x,x
3. register memory (not very clever)
L x,=A(0)
LG x,=AD(0)

Answer / sam
I'm assuming something like
R0 EQU 0
R1 EQU 1
:
Rx EQU x
is coded somewhere in the program

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????
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?
