Yes, I know some hardware supports AM24 only, some supports AM31 and AM24, and some supports ALL of AM64, AM31 and AM24. Ideally, when you are producing a load module that uses the 32-bit registers found all the way back to non-XA 370, it should be AMODE-neutral and run in ALL THREE AMODEs. >Everything you are doing with your "32-bit" shenanigans will not work on >real IBM 370 hardware because it cannot run AMODE 64. It doesn't need to. That's why the gods invented z/Arch because IT CAN run AMODE 64. BFN.
