use conditional codes

Postby dn2012 » Tue Feb 28, 2012 5:33 am

Hello,

I have been requested to use conditional codes in the Job attached. Currently our Job do not stop at an abend step.They want job should stop at an abend.
I am new to JCL.
I do have some programing experience in other languages (PL/SQL, SQL).

Re: use conditional codes

You do realize, I hope, that the second IDCAMS step - the one that does the REPRO - is not using the same dataset that is the output from the sort step? Or did this step come from a second job that was run if the first job completed OK?

Re: use conditional codes

Postby NicC » Tue Feb 28, 2012 11:03 am

A job will ALWAYS stop at a step that abends UNLESS you provide condition codes on subsequent steps to ignore the abend. However, a non-zero return code is not an abend so execution continues UNLESS condition codes say otherwise.
You do not need to program to use JCL condition codes as JCL is not a programming language. (Neither are PL/SQL or SQL - they are query languages. JCL is a Job Control language).
You need to refer to the JCL Reference manual and User Guide manuals - look up COND parameter and IF/THEN/ELSE/ENDIF in the Reference manual index and the chapter on Processing Control in the User Guide (chapter 10 in my version).
One way to get execution to stop is to try and execute a non-existent program (EXEC PGM=NOTFOUND) when you get an unsatisfactory return code.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

To enlarge on NicC's reply: most shops have -- and have had for decades -- tiny little programs written in-house that provide a controllable abend. The TS should overcome his fear of talking to his senpai about anything save cricket and Bollywood and ask how this is done at heesh site.
"You have sat too long for any good you have been doing lately ... Depart, I say; and let us have done with you. In the name of God, go!" -- what I say to a junior programmer at least once a day

Re: use conditional codes

I am thinking to use following code in LISTCAT step.

//LISTCAT EXEC PGM=IDCAMS, COND=(0,NE,IMF1)

what do you think? Will it work with IDCAMS

Thanks

the JCL condition code checking logic does not depend on the programs being executed, just on the return code

Hello,

The jcl posted and the question have nothing to do with an "abend". . .

You need to understand the difference between an abend (System or User) and the intention to control processing due to some return-code(s).
Hope this helps,
d.sch.

Re: use conditional codes

Postby dn2012 » Wed Feb 29, 2012 8:56 pm

I have used following logic:

EXEC PGM=IDCAMS,COND=(0,NE,IMF1) --- If previous job IMF1 not equal to zero, it will not run.
EXEC PGM=SORT,COND=(0,NE,LISTCAT)
EXEC PGM=IEBGENER,COND=(0,NE,SORT)

Does it make sense?

Thanks

COND Codes where not working in your Job.

000C,00000000,NONZERO,D120229,T0856,IDCAMS
#(001) PGM(IDCAMS ) ELAPSED(00:00:00) COMP(00012)
0000,00000000,FLUSHED,D120229,T0856,IDCAMS
#(002) PGM(IDCAMS ) NOT EXECUTED
#(003) PGM(SORT ) ELAPSED(00:00:01) COMP(00000)
000C,00000000,NONZERO,D120229,T0856,IDCAMS
#(004) PGM(IDCAMS ) ELAPSED(00:00:01) COMP(00012)
0000,00000000,FLUSHED,D120229,T0856,ITDWTOR
#(005) PGM(ITDWTOR ) NOT EXECUTED

) ELAPSED(00:00:02) TURNAROUND(00:00:02)

Any help will be appreciated

Stop duplicate posting.

You cannot use a condition code to refer to another job. Also, show the full EXEC statements from the // to end of statement.
The problem I have is that people can explain things quickly but I can only comprehend slowly.
