The SYMBOLS= keyword is on the DD DATA or DD * JCL. It controls what symbols
are substituted in the instream data sets ... so yes, in places like:
REPRO INFILE(GIMZPOOL) +
OUTDATASET(&HLQ..GLOBAL.CSI)
The way the substitution works is it looks to compress blanks to the right of
the symbol. It will compress strings down to 1 characters trying to keep
characters in the same column that they are in.
The substitution happens "just in time" as the application is running to pick
up the latest JES symbols. JES symbols are dynamic as opposed to JCL symbols
that are static.
I did not mention PARMDD because it did not hit JES2 at all so there was
nothing to really talk about.
