I believe the behavior was provided to support semi-unattended operations with a real card reader so the operator needn't press EOF before each job. But how might it depend on whether the job is submitted via: o Real card reader? o Virtual card reader to VM guest? o SYSOUT=(,INTRDR)? o TSO SUBMIT? o ISPF SUBMIT? o JES2? o JES3? o NJE? o Can it be fooled by:: - DD DATA,DLM='//'? - DD DATA,DLM='xx'? Could a mischievous programmer read sensitive data in a following job? I know with the SDSF REXX API, but not the GUI, I can read data after the '//'. >At 10:04 AM 12/22/2023, Bob Bridges wrote: > >>I should know this - I've been using JCL for decades - but I find >>I'm uncertain about something I haven't done in a while.
