Mainframe, MVS and zOS Discussion

Hi,

In a JCL which have 100 steps. In that, if I want to execute only the 13th step then I can by using RESTART=STEP13 in the job card. I alos need to put a null statement after the 13th step. Is there any other way to do this? I do not a way of doing it. Can there beother way, please suggest me. I faced this in an iterview which went almost good apart from this question.

First of all, realize that this a trick question; you'd seldom if ever want to do this in real life.

Possible ways of doing this would be:

• Deleting all lines after STEP13, and either using the TSO SUBMIT command or writing the modified JCL to the internal reader, depending on the environment.
• Enclosing STEP14 through STEP100 in a suitable IF-THEN-ELSE construct.

Hi,

Just adding one more way to Akatsukami..
Code on Job card

and ... what would be a practical use of this horse manure(*)

normally horse manure would be much more useful than these kind of gimmiks

Code: Select all

Restart =STEP13,COND=(0,LE)  

on Job card

Thanks for the other option Chandan. But if add only this steps after 13 will anyways get executed?

Hi,

We can also make use of IEBEDIT.

Once your step 13 executed with Restart parameter then COND parameter on JOb card will be applicable to all other steps and (0,LE) will be always true

This would include Step name STEP010 of Jcl JOBNAM1 present in library
USERID.ABC.JCLLIB

Thanks. Ido see IEBEDIT answer on many places on websites but in my real JCLS I have at work place I have never seen it being used. Is it used only in theory and for interviews?

COND=(0,LE) is like, if the RC of the previous step is less than 0 don't execute "step13", which is not possible. So agree step13 would execute but rest of the steps will also execute. I was not supposed to execute step15, step15...

IEBEDIT is a standard IBM utility. Refer to the utilities manual for information.

A job COND parameter applies to all steps, so the COND=(0,LE) would apply to all steps after STEP13.

As Robert mentioned When I mention COND on JOB parameter it will applicabe to all steps of Jobs, as I am restarting from step 13 it will anyways execute as there is no previous COND parameter to check.
Once Step 13 executed it will apply COND=(0,LE) to all other steps and COND=(0,LE) is like the RC of the previous step is less than or equal to 0 don't execute

I hope its clear else I can suggest you to test it out and let us know if something not working

Thanks,
