Done -  the original  posts are  on JES2-L.  They deal  with DIAGNOSE  for MVS
guests and the required LRAs.

Interesting - shouldn't it always be in the range 0-4k?

Ok, I wasn't clear in my wording (and we didn't get MVS before 3.1.0).
Of course  with support  I meant  both real  and virtual.  But I'd  expect the
macros (GETMAIN e.g.)  to let you exercise control according  to the functions
of the control program.

If you  have (online) storage above  16M (whether from native  mode or because
you defined  the machine with more  than 16M in  VM) you likely will.  If your
machine has 16M or less in the VM directory you will not.
