Hi there,
APAR PH00902 has this neat get-out clause...
<snip>
The presence of a mnemonic in the above lists does not necessarily mean that
the corresponding instruction is available to use. The list may include
mnemonics reserved for possible future use, so that if the corresponding
instructions are made available before the next major hardware level this
will not result in any new potential clashes with library macros.

There were not yet any exploiters and they aim to keep it that way!
Geez, you would think the several-year lead time on hardware design would
have given the DFSORT team a decent head start.

I asked IBM about this pre-GA and was told that the doc was
*deliberately* left out of PoOp because there were not yet any
exploiters! WTF? How can anyone exploit something that isn't documented?
My "push back" on that was left unanswered... :-\
