Ah, the
As Tom Marchant pointed out, all supported z/OS releases (and those from
z/OS 1.6 onward) require z/Architecture and support 64-bit virtual.
Customers do not enable 64-bit functionality on such releases; it cannot

Incredible! How does this happen?
Is there any operation that requires storage above the bar

Hum, I really find bit 7 amusing. What does STFLE set that bit to when
STFLE is not available. No, wait, what?

Peter,
This is my first adventure into the 64bit world. So I am sure you can
understand my caution with customers z/os systems. I wasn't aware that the
feature couldn't be turned off. My issue is more trying to allocate a 64 bit
storage and it failing ...I appreciate everyone's help.
