Be sure that you know your target machine.
z/OS runs on all z/Architecture machines, not all of which support LT (and
some customers still have such machines).

Or use the IEABRCX macro. It allows you to selectively enable/disable/push/pop
the conversion. We do this only around "stubborn" IBM macros.

With a special tweak for "SH =H'-32768'"? This can be much obscured

Another quick win is to replace branches with jumps (B to J, BE to JE,
and so on). It will take more work to replace them in macros and figure
out ways to handle branches into branch tables. It seems like you're
well on your way to removing base registers for addressing code!

Dear all,
thanks for the good advice. I forgot to mention the background of my question:
I'm currently looking into "modernizing" 20-year-old code (some of which is by
me, so I feel a bit old, too).
While I have to add some more functions, I will also take the opportunity to
improve the code.
