Hello Ed,
I agree that base-less is somehow misleading,
but today I had the problem to explain to my managers what I am doing,
and why this is good for the ASSEMBLER developers, and the managers
always nead a kind of keyword, and "base-less coding" works very well as
a keyword
for the managers - no matter if they understand what it is or not - in
fact, it is very
hard to explain it to non-techies.
Maybe "base-less with respect to the code area" could be a valid
extension -
of course, there will always be base registers for the data areas in the
near
and not-so-near future.
Kind regards
Bernd

Of course! And, if they are you use MF=E instead of MF=I format.
For the GETMAIN, note that the "L" for the literal loaded into R15
requires a base register able to address the LTORG area.
Literals, constants, and working storage DSECTs require base register
coverage. This is why I don't like the term 'base-less' to describe code
that uses relative branches.
