To find the TIOT, a colleague uses GETDSAB, then pulls DSABTIOT out of that.
I've always seen:
L R3,540 Get TCB address
L R3,12(,R3) Get TIOT address
...which seems a tad bit mo' shorter :)
Looking at GETDSAB, it's beautifully commented with over 500 lines of preamble,
none of which explain what the DSAB is or why one would want to get one (OK,
that's a different rant - z/OS doc in general is really short on theology; z/VM
doc is MUCH better about this).
So the real question: I expect GETDSAB is the documented interface, but is the
two-line approach common? Aside from theoretical changes, is there any reason
not to use it?
