Hi 

I have a self modifying assembler program 

Which sets MVI BRANCH+1,X’F0’ or clears MVI BRANCH+1,X’00’ there are a number 
of these statements in the program 

Using the AT CHANGE command is there any way to track down which one of the 
many instruction in the above example sets or clears the branch 

I would assume I would enter the command after the program base register has 
been established 

So if branch + 1 is X’AB3’ off of register 12 

The command I would enter is AT CHANGE _STORAGE (%R12 + X’AB3’::1) I did this 
and the break point seems to be hit every time this program is called 

Thanks
