I have been following the ASMA034E discussion and am interested in learning how
to do the new-fangled relative branching stuff.
Can someone point me to a reasonably simple example? I learned my Assembler in
the 80's and have been using that way of coding ever since. I think it is time

Or you can just put CODE LOCTR before your entry point instruction.
Here is the slightly edited beginning of one of my modules. This gets the
copyright constant first in the object code, and avoids any extra branches.
(ABEND EDCPRLG is an entry point.)

The other key tool for eliminating excessive base register dependencies is
LOCTR. Too long a topic for an e-mail, but LOCTR lets you code instructions
in whatever order you prefer, such as putting DC's at the "bottom," and lets
you use LTORG in the normal fashion -- while still putting everything

So where you have a problem with what is generated, turn off IEABRCX. Then turn
it back on. The documentation explains this.
The macro could only have so much smarts.

You can but you need the enhanced object code format to do that. GOFF? Some

A nitpick, but why would you change everything to Jxx except BAL/BAS? JAS
would be more consistent.
IEABRC is pretty clever, but I've found it pretty quick to just rename all
the B* to J* and clean up the exceptions.
However, in my recent environment, virtually no branches of any kind were
Just habit. Just what I do.

A more modern (over 20 years old by now?) would suggest not having a USING
for your "code" at all, but rather using relative branch with one register
set up to point to your static data and a USING for that. It is relatively
infrequent that your static data would exceed 4K, and even if it did
