No impact unless you happen to have conflicting symbols.

Yes, we've only just turned it on in a couple of test systems.
My concern is what impact it will have on systems where the job scheduler does 
its own symbolic substitution (e.g.CA7) and I will follow this thread with 
interest

Is anyone else pushing back on turning on batch system symbol support?   We've 
yet to do so, for the very reasons that IBM hadn’t supported in batch all 
along.  My main concern is unpredictable results.

Am I worrying for nothing?

Yep, need to make sure SYSSYM=ALLOW for that jobclass,



CLASS og XBMProc DupJob JobRC Active SysSym
1 PIN) NO MAXRC YES ALLOW
2 PIN) NO MAXRC YES ALLOW




in a STC I run at IPL time I do about the same....



//CLEAN EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *,SYMBOLS=EXECSYS
DEL 'ATTS.PROD.&SYSNAME..IPLINFO'
/*
//IPLINFO EXEC PGM=IKJEFT01,REGION=0M,PARM='IPLINFO',

In my JES2PARM, in the definition of the job class that I'd run this job in, I 
specify SYSSYM=ALLOW. I'm sure you could put this in dynamically with a $T of 
some sort. You'll also need the two periods as Rob stated.

I understand what you're saying Rob, but that was one of the variants I tried. 
It still produces the same error
