Sir Mike the Prestidigitator,
Would it not be an obvious omen to us that the Priests of Endicott
have never blessed us with a TERSE MODULE. Unlike our brethren from
zee Other System we don't need this. We're already very lean and
mean and don't need no terse. With more of z/VM going OCO, things

Doesn't the IBM VM 2nd level support group want sites to send them VM dumps that have been
compressed by TERSE? Perhaps at one time you had a file that you wanted to send to IBM,
and they sent you the VM TERSE module so you could compress it first?

Too small was only meant in direct relation to z/OS dump sizes.
I believe that the typical z/OS system creates substantially larger dumps
than the average large z/VM system. YDMV (Your Dump May Vary).
It's all relative.

There are no publicly/commercially available implementations of SSH (inbo

or outbound) for VM/CMS.
I have been asking for a long time and the most polite answer I get is to
use a linux virtual machine as a communications intermediary. I have also
gotten answers like VM doesn't need SSH
Perhaps a polite request to a friendly local IBM CE/SE might produce the module in
question. It's worth a try, imho.

Basically, the answer to cloning VM depends on your environment. On the one
