Based on the relatively code path supported, it appears to be that the best
use of it to replace/simplify the more complicated PLO cases where there is a
lot of setup and the need for working storage. Don't know which will get
better performance.

As you might assume, the operating system uses transactional execution.
A caveat: you cannot use it unconditionally. Even if you know you are on
the right machine. One reason for that is that it cannot be used if z/OS
is running on/under VM. Another is that we have given the customer a knob

I *considered* it for a problem of updating a queue in a multiprocessor
reentrance situation. I ended up solving the problem with CSST which seemed
like a simpler approach

I haven't used it yet. When I first heard about it, I had some ideas of
how I might use it, but can't remember any of them now.
Have you seen this SHARE presentation?

OK, I guess I asked my question poorly. And I should not have said anything
about the PLO (instruction, not Mid-East organization)

I'm just curious. I don't, personally, have any need for it at present. I can
envision some need for it, such as "atomically" incrementing one variable by
some amount and decrementing another by that same amount (like
DB2 does within an SQL transactio
