We have a prototype for a z/OS Unix shell command wrapper for IAZSYMBL. The envisioned use of this would be to be able to integrate JCL/System symbols with z/OS shell scripts.
I was hoping to solicit your opinions: - would this be useful? What are interesting use cases? - suggestions for improvement This would be a command that we would plan on making available free as a new command in the Co:Z Toolkit.

Also: you need "set -o pipecurrent" when piping jessym output into "read" or "." ) Here's the proposed syntax: *> jessym * usage: jessym name or: jessym [-p <prefix>] -s name-pattern ... or: jessym [-p <prefix>] -x name-pattern ... or: jessym [-r] -c name=value ... or: jessym -u name=value ... or: jessym -d name-pattern ... *Form 1: Display the value of a single variable:* *> jessym A* B *> set -o pipecurrent * *> jessym A | read -r myvar* *> echo $myvar* B *Form 2: Show variables matching patterns:* *> jessym -s SYS* * SYS_CORR_CURRJOB='S0000434DTLZOS01CC27C5EA.......: ' (no pattern defaults to "*") - *> jessym -s* SYS_CORR_CURRJOB='S0000434DTLZOS01CC27C5EA.......: ' A='B' *> jessym -s | . /dev/fd0* *> echo $SYS_CORR_CURRJOB* S0000434DTLZOS01CC27C5EA.......: *Form 3: Show variables (with exports) matching patterns:* *> jessym -x* export SYS_CORR_CURRJOB='S0000434DTLZOS01CC27C5EA.......: ' export A='B' *> jessym -p JES_ -x | . /dev/fd0* *> echo $JES_A* B *Form 4: Create a new JES System Symbol:* *> jessym -c C=abc* *> jessym C* abc *> jessym -c C=abc* JesSymbols[W]: IAZSYMBOL rc=0 RET=4 REAS=28 (create with replace option:) *> jessym -rc C=def* *> jessym C* def *Form 5: Update an existing symbol:* *> jessym -u C=ghi* *> jessym C* ghi *> jessym -u X=yyy* JesSymbols[W]: IAZSYMBOL rc=0 RET=4 REAS=4 *Form 6: Delete symbols:* *> jessym -d C* *> jessym -d A** *> jessym -d FOO* JesSymbols[W]: IAZSYMBOL rc=0 RET=4 REAS=4 *Submitting JCL from a shell script using symbols:* Since the z/OS Unix "submit" command (or TSO submit!) doesn't support passing JES symbols into the internal reader, we plan on enhancing the Co:Z "todsn" command to allow this, perhaps something like: *> fromdsn "//my.jcl(xxx)" | * * todsn -x "sysout(a) symlist(*)" //INTRDR* *Automatic invocation under COZBATCH* We will probably enhance COZBATCH so that all symbols are exported with "JES_" prefixes before your shell or program is started.
