Then the binder should have given you a warning about the 3 byte adcon.
Even though warnings tend to have the "acceptable" rc=4, they should still be
examined.

Nothing mentioned-

I do know of one such list; but it is highly unofficial, not of course
mine, and not for me to disseminate. Someone else may be in a
position to be more helpful.
Worth repeating is that nny such list, like its elements, is
obsolescent when it is published.
Such obsolescence is also a problem wit
Private reply.
Is there a list of the "stereotyped" code sequences? I'm already aware
of the LA and MVI/MVC sequence.
People on the list might like to see a complete list. Would make a great
SHARE presentation!
