Just wondering if there are any concerns left with setting SWA to SWA=ABOVE
in the JES2 Init deck?
I remember something long ago and far away that if a program went after a
UCB it was a token with this setting and not the real UCB address. Which
could lead to an S0C4.
Of course my fuzzy brain cell may be mis-remembering.
Definitely misremembering. UCBs are not in SWA, they are in SQA/ESQA.
Programs that don't use SWAREQ or equivalent coding to access/manipulate SWA
control blocks will not work with SWA=ABOVE. I can't imagine any modern ISV
product that doesn't do this properly. (But, just because I can't imagine it
doesn't mean it can't happen.) User code is an entirely different story...
