Subject: [External] Re: does anyone recall any details about MVS/XA?
Under MVS/ESA we had expanded storage. Expanded storage allowed each page to be
addressed using a 32 bit
In my first shop we did a conversion from OS/VS1 straight to MVS/XA (IBM made
us an offer we couldn't refuse). This was a little before CBIPO so first had
to lay down a starter system that was some flavor of MVS/370 or /SP. I say
that because it ran under our VM/SP (actually HPO) system.
