I was mentioned several times. Yes, there is no enough DASD storage to 
page all 64-bit A/S. AFAIK MVS still menas Multiple Virtual Space 
(Multiple = 32k), so you can multiply your abstract number by 32k and 
that way get more abstract number
...

I still think that this argument is specious.

There has always been more space on DASD on the floor than installed on a 
processor.

IE: at a former shop we had a total of 32 GB of mainframe memory installed.
We had 26 TB of DASD installed.
We had five images with 4 full-pack 3390-3 locals each. Giving us another 56 GB 
of virtual.

The data on disk is always going to out-strip the data in memory.

The architecture to support this kind of storage with the expected growth is 
going to fail (in its current incarnation) long before we can exploit a full 
64-bit address space.
