The basic form of ADDRESS does not allow an expression for the environment,

No, I'm saying that the second script is a more expensive version of the first.
'ADDRESS foo bar' evaluates bar and passes it to the foo environment. If you
omit the command, then 'ADDRESS foo' just sets the default environment to foo.

Why would it require authorization? Just adding it to the ISPF command table or

ISPF EDIT SUBMIT calls TSO SUBMIT. Did you mean that you want to RYO?
It is easy to copy some or all of the data to an internal reader, followed by a
'/*EOF'. If you need to capture the jobid, a small assembler program can do
that using the ACB/RPL interface.
--
Shmuel (Seymour J.) Metz
I don't see where the OP is asking for the job number. If he doesn't need it,
then there's no need for any assembler code.
If he does need the job number, then OUTTRAP won't help, since he doesn't want
to use SUBMIT. In that case, a small program using ACB/RPL can copy to the
internal reader
In this case I would write a small rexx program to call the assembler. As
it is rexx, the name typed assumed to be a macro. BTW, the problem can
easily be solved by rexx OUTTRAP (to capture the job number).

If I read this right, OP is asking for a replacement for the edit SUB
command, which does some alternative processing before the job is
submitted, but is basically quite similar to the original SUB.
If a Rexx EDIT macro is not acceptable, my first instinct is to look for a

We are in the middle of a first time site switch test where we used CBU to

was discovered that Group Capacity had not been set on the box at the alternate

What you are trying to do is effectively an ISPF Edit Macro that you call $UB,
and it will work with Edit and View. You can code an edit macro in assembler.
It is just a load module that would reside in ISPLLIB (or steplib or linklist).
Lionel B. Dyck <><
Website: https://www.lbdsoftware.com
So write an edit macro to copy the all the lines onto a Rexx stack and use
"SUBMIT * END(//)" (or similar) to submit it! You can then use OUTTRAP() to
capture the message from SUBMIT and stop the screen breaking up.
