Do you mean private is too small?

Not sure. I was responding to Peter Relson.

A question for Wayne: can you find out the size of low private on your
system (there are probably "pretty" ways to do this, such as some VSM
health check, but if you can get the value of GDACSA that will let the
answer be ascertained). CVTGDA (offset x'230' in the CVT) has the address
of the GDA. GDACSA is the 4 bytes at offset x'6C'

CSA 00800000 00CB2FFF 4812K ........ (GDACSA ?)
Private V=V 00006000 007FFFFF 8168K
