All:
I have a question about something called
'customer anchor table entry' . My colleague said IBM can provide this
entry to a ISV like use so we can place an address there for routines. I
think it's like a vector address .
Has anyone heard of this ?
Yes I know about it and I kinda know the history of it. I'm not
sure but I think I was the first one if not one of the first to
apply for an entry when it was announced back in the mid-'90s
when I was still working on ACS/WYLBUR and attended the "Vendor
Disclosure Meeting"s in POK.
It solves the problem of the TCBUSER field in the TCBs, and the
CVTUSER in the CVT. The problem being, who owns it and who can
use it and NOT step on someone else.
It gives you an ANCHOR address where you can do a GETMAIN/STORAGE
OBTAIN for CSA/SQA storage and store the address of that storage
in your slot.
How you serialize it, use it, etc., is your problem as an ISV
with multiple, or just one, product.

Steve Thompson
