My only point was the SET wasn't needed the way I used symbols. It's
hardly any big deal if it's needed for library PROCs. The fact that
there doesn't seem to be any obvious logical reason for it, is just one
of things you take for granted with JCL.
Why don't we just skip the JCL, and write our jobs in REXX? The two
main things JCL does, EXEC and DD, are just as easy in REXX, (call,
alloc) with a ton more flexibility. EXPORT, SET, IF, and symbols are
lipstick for a pig.
All you must keep in JCL is the JOB card, and a standard EXEC PGM=IRXJCL
+ SYSEXEC DD. Everything else you can code in an actual programming
language.
JCL is fun as a puzzle-solving activity (sometimes), but for busy people
trying to get their work done, it's been a black cloud since 1964. Even
Fred P. Brooks said he didn't like it.

I've gotten good results with the EXPORT before the PROC
Which means the EXPORT needs to be in the calling job, not the PROC. My
examples used inline PROCs for convenience, but I was trying to do it
with a PROC in a PROCLIB. If the EXPORT needs to be before the PROC, the
job needs to know exactly which variables the PROC needs exported, which
negates some of the convenience of abstracting stuff into a PROC.
Does it not suffice to code EXPORT before SET, but in the PROC?
(But then are symbols exported to open code, outside the PROC?)
The best solution seems to be SET VAR=&VAR in the PROC.
Hardly practical if the vaue of VAR contains metacharacters. JCL
sorely needs HLASM's DOUBLE BIF.
