Hi,

How to make one step in JCL to Null step(IEFBR14)? below is step shown.

//STEP01 EXEC BATCD45
//CBOCNTRL DD DSN=PCT.CBOCNTRL.INFILE,DISP=SHR
//TEMPDSN DD DUMMY
//SYSIN DD *

With so much useful information given by you, it's very hard to know where to start.

1) Change the JCL,
2) If it's in a PROC - change the PROC

That's the only way it can be done

Hi Expat,

Thanks for reply.

What needs to be change in JCL or PROC? I need to change the DISP parameter for deleting DSN or any other. Please guide me.

If you explain EXACTLY what it is that you want to do

Why do you want to change a program to IEFBR14
What, if anything, do you want IEFBR14 to do

Is this instream JCL or a PROC

//STEP01 EXEC BATCD45

looks like a proc Expat.

But what the hell why do i bother, its all your game.

You are showing a procedure, program is executed by PGM=pgmnme. You cannot override a program name in a procedure unles it is coded as a symbolic (&PGMNME). If you do not want the dataset to be affected then provide an override //stepname.CBOCNTRL DD DUMMY but as the DISP is SHR IEFBR14 will not affect it in any way - nor will job termination.

Hi,

Thanks for your reply.

Its not an instream PROC. I need to disable the step01. that it. so, this change is fine or not as shown below.

//STEP01 EXEC IEFBR14
//CBOCNTRL DD DSN=PCT.CBOCNTRL.INFILE,DISP=SHR
//TEMPDSN DD DUMMY
//SYSIN DD *

Thanks,
Dilip.

The only chance that your JCL will work is if you have a PROC called IEFBR14 because that's what /STEP01 EXEC IEFBR14 is looking to do.
The //CBOCNTRL DD and other JCL cards will be appended to whatever's in that PROC.

You still haven't explained EXACTLY what it is you're trying to achieve. If you can just change the JCL, why not use //STEP01 EXEC PGM=IEFBR14 or, better still, just edit out the step.

Garry.

No - (1) because you do not have PGM=IEFBR14 so the interpreter will look for a procedure called IEFBR14 and (2) as I said before, you cannot override a program in a procedure unless it is symbolically defined. If you do not have a procedure then just delete the step before submission. If you normally need the step then cancel the edit session after submitting the job and any changes will be backed out.

There must be about a million different ways to not run a step.
Unless you have a further requirement, why go to the bother of changing it to IEFBR14?

Delete in the editor is pretty effective, as has been suggested. If you think you might want to sometime go back to the original, just make a copy of it. Much less error-prone than changing, and then changing back.

Why do you want to nullify the step?. If you don't want the step to be executed comment it or else if you want to execute a job with one null step. just use the below step

Phrzby Phil · Posted: Thu Apr 21, 2011 6:07 pm

Changing the program to IEFBR14 will not nullify the step, it will just change the program. Any JCL that allocates or deletes datasets will still be in effect.

In case anyone else has not said so - BE REALLY CLEAR ABOUT WHAT YOU WANT TO DO.

I've been using something like this for 10+ years, without z/OS raising a stink -

Phrzby Phil · Posted: Thu Apr 21, 2011 6:51 pm

Bill -

Why not use a first step IEFBR14 to set RC=0?

Also, your first ENDIF is dangling.

Bill O'Boyle · Posted: Thu Apr 21, 2011 7:16 pm

Phil,

Yes, you're right, the first ENDIF is extraneous, so it can be removed.

I guess IEFBR14 could be used to set the MAXCC, but I know the IDCAMS step works too.

I've got DR Job's setup for off-site DFHLOG Stream Delete/Defines, using ON/OFF variables like this.

These Job's execute the same way every year with any trouble.

Bill

All those experts, reacting on a crap question. What happened to you guys? On shitty questions give a shitty response. After all those guys are going to do your jobs today or in the future.
