o System Symbol Substitution in BATCH Jobs • Any system symbol (IEASYMxx) can be referred to in JCL • JOBLCASS SYSSYM=ALLOW|DISALLOW option • Substitution occurs at conversion time At last? o Symbolic Substitution in Instream Data Sets • SYMBOLS= keyword on DD DATA or DD * JCL SYMBOLS=[ ( ] JCLONLY | EXECSYS | CNVTSYS [ , DDname]) • Substitution as records are read by application May I assume this means the value of symbols in the context of the EXEC statement? • Blank elimination to try to make things fit • Overflow if possible, I/O error if not Embedded blanks, or only trailing? Will this affect the LRECL of a RECFM=VB instream data set? o Passing Symbols on INTRDR • SYMLIST= keyword identifies symbols to pass Will this be a keyword supported by TSO ALLOCATE and BPXWDYN, presumably as a TU for SVC 99? No mention of long PARM or PARMDD?
