Can this be a continuation? Comment?

Postby Howard-Training » Wed Oct 02, 2013 10:08 pm

I've taught JCL but this is new to me. Can line 2 "// F G088C,..." be a continuation? A comment? What is it?
//STEP1   EXEC PGM=IEFBR14                                              00000030
// F G088C,F=LECD,C=2                                                   00000040
/*                                                                      00000050
//STEP2    EXEC PGM=LE...

These look like PARMS to me but I don't recall coding anything this way.
We received this from another site and I don't have any tools to run or test it here.

It is an operator command directed at job or started task G088C.

Something like this is very problematic.
  1. Your system may be set to not execute the command at all.
  2. If it is executed, it is executed when the job is "converted."
  3. If it is executed, it is executed on the system where the job is "converted," which may not be the system where the job executes.
  4. If it is executed, I don't know where any command output will appear.
  5. Execution of the job may be delayed for one reason or another.

Thank you. I will puzzle over how we should treat it. This IEFBR14 is the only step inthe job so I'll have to ponder what possible use it has other than as a quirky way to document.

It is NOT a "quirky way to document" -- it is an operator console command. For example (assuming appropriate system access), if the line read
// F CICSX,"CEMT P SHUT"
when the job is converted/interpreted by JES, CICS region CICSX will start its shutdown procedure.

Remember that every job must have at least one step. If this job has no purpose other than to send a MODIFY command to a started task, IEFBR14 provides a null step.
