Where are the LPP and HIS instructions described? I don't see them in the
latest PoPs (-08) that I have.
Thanks.

David Stokes posted the link to the documentation of these
instructions.
I haven't checked them en detail- they look like the ones I am using

Perhaps some mainframe customer could prepare a business case why IBM should
address the 24-bit VSCR issue. A SHARE requirement, anyone?

Care to explain?
I was referring to the practice of using GETMAIN to acquire working storage
areas. This technique is most often employed by RENT programs.
Also, I assum
For one thing, if a page has not been modified since it was paged in, and
it's slot on backing store has not been reused, it can be assigned to
another address space without first writing it to disk. I believe this is
called "page-stealing".

Regardless, nowadays, any 24->31 bit conversion is underreaching;
shortsighted; mostly wasted resource. Go for 64! Even while RMODE 64
execution is mostly unsupported, the 64-bit interfaces can be coded
and the code run AMODE 64 below the bar in the interim.

As far as requiring "smarts" to see out eligible GETMAINs, my point was that it

Looks like ORG's alignment is unconditional so it may generate different
offsets from CNOP when the location counter is already correct.

As Tom Marchant has already pointed out, Hobart Spitz's view of page
stealing is mistaken.
Perhaps even more important his view of how the ASM [Auxiliary Storage
Manager] works is also mistaken. No page that has not been modified
is paged out. (One of the minor but important merits of reentrant
Thanks for the corrections.
