No I didn't; you simply responcded to something that I hadn't written.
What I actually wrote was
Note: once you execute "address ISREDIT", there is no need to
put "ISREDIT" in front of every command.

No. The first one uses on address statement followed by a number of
expressions that are directed by REXX to that environment.
>The other school of thought puts an "ADDRESS ENV" on each statement
The third one does both. That's what was in the code under discussion.

Note that there *is* an initial *ADDRESS ISREDIT* in the code under
discussion, from Message-ID:
<[EMAIL PROTECTED]>.
>You prefer school (1) - I prefer school (2).
And my position is based on code readability and maintainability, not
efficiency.

No - there is nothing to restore, because it never changes the
environment. Would you claim that there is a PUSH/POP USING in the
anaologous code
STH R0,DCBLRECL-IHADCB(R9)
just because the DCBLRECL reference isn't resolved via the current
USING?
