Hi there,
I hate the term base-less it means 'without foundation' !
I'm not sure what the fuss is about, I've been using base-free code with
literals for years.
eg.
LARL R3,=C'ABCDE-'
MVC THERE(5),0(R3)
Yes, it's a 5-byte literal extended to 6 to keep the LARL happy
LARL has a range of +/- 2G which should keep most coders happy, so it
doesn't matter where the LTORG is

I finally am to the point where I no longer need to worry about
specific customers having hardware that does not support relative
instructions, so I am updating some macros I provide to be baseless.
What is the 'preferred' approach to macro generated constants? In the
past, I have used both inline constants that I branch around, and
ltorg literals (=c'x').
In the past, I have been bitten by using ltorg literals and the client
did not put a LTORG after my macro causing a 'no active base register'
issue. So, I am thinking inline with a BRAS is better.
Maybe there is another approach that I missed?
Suggestions?
