Subject: Replacement for TM instruction
Hi all,
I would like advice because i have a situation where i need to check a bit of a
storage area, usinganother storage area as a pattern and not an immediate.
I have something like this :
A DC X'1C'B DC X'08'
TM A,x'08' JO X
But instead of using x'08', i need to use the variable B in the comparison,
because the content of B may change.So, i would need something like this:
TM A,B
How can i do that ?
Thanks in advance.
Best Regards
Ituriel do Nascimento Neto z/OS System Programmer
