Gentlemen,
Thank you very much for your ideas and time.I was considering to copy variable
A to another place and, since i only need to check one bit, do a NC and then a
CLC, but i think your suggestion of EX is more elegant.
A DC X'1C'
B DC X'08'
C DC X
MVC C,A
NC C,B
CLC C,B
JE MATCH

No, I meant execute, as in *either* EX or EXRL, a TM. I was, of course,
assuming that TMY was not necessary and that TMHH, TMHL, TMLH and TMLL were
useless for the purpose.

For a test of a single bit you can do a logical and on a copy of the byte or
use NRK.
For testing multiple bits you can execute a TM.
You mean, EXexute a TM.
