Thank you for your correction to my earlier message, I have gone 
under a misconception of S/360 architecture for many years and so I 
appreciate your response - I had always attributed MVS VM services to 
the S/370 and thought that S/370 was the first to do such things in 
the IBM mainframe family as one of its key differentiations to the 
S/360.  Clearly I got that wrong.

One has to love the remarkable level of experience of those who 
participate on this list.

You know BAL!  I am impressed (not that my being impressed should 
mean anything to anyone, but rather think about how really neat is is 
to have such people as you and others with such levels of computing 
history and knowledge right here on this list - that is what I 
continue to find so very impressive).

Thanks again.
