Back in the 1980's I recall an IBM product called CICS/VM being available. I'm not sure if it is still around today, nor whether it required a z/OS guest - try Googling or searching ibm.com.

I find this hard to believe and have never heard of this being done in any size, shape or form. I think he is blowing wind. Can anyone comment on this. If there is any truth in this please advise where I can find some documentation on this. Thanks
