Hi,
Would this work?
Definitely not. It's the same problem as before.
TM requires the mask as part of its instruction.
As others have suggested, the B operand can be supplied
by using EX.
An alternative would be to use NC to test for the single bit.
MVI B,X'08'
MVI A,X'1C'
TM A,B
BO LABEL
A DS X
B DS X

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.
