If COND=(0,LE) is specified to the first step of JCL

Hi All,

I have two questions to ask.

1. If COND=(0,LE) is specified to the first step of JCL?

I answered like " For first step if COND is specified it is always false and first step executes always if no restart"

2. If JCL have 5 steps S1, S2,S3,S4,S5 in the same order.

How to change the execution irder like excute S4 sfter S5?

I answered to run onetime jobs.

Hi Anand,

You have answered correctly as far as i know.

For the first question, condition code can only be used to control the execution of subsequent steps depending on the current step 's completion code.

Here, since the COND parameter is coded in the first step, it will be executed anyway as the condition is false.

For the second question, the only way to run the step S4 after S5 is to move the job step down or execute it in a different job.

Hi anand,

For your first question,

COND parameter is not coded in the first step.

For your second question,

Use restart parameter in the job card like this

restart=include(step1, step2, step3, step5, step4)

Correct me if im wrong.

With Regards

Really sorry,

Im wrong.

We solve the problem by using IEBEDIT utility with EDIT TYPE = include, Stepname = (Step1, Step2, Step3, Step5, Step4) in SYSIN statement

I hope step5 isn't using output from step 4.

No input for step5 from step4.

Rajesh,

I tried using IEBEDIT utility to see if the order of the steps in a job can be changed. It looks like we cannot change the order of the job steps through the INCLUDE type in the EDIT statement, but we can only include or exclude the job steps from one or more jobs.

For example,

I ran the below IEBEDIT step and its input contains a job with 5 steps (R010, R020, R030, R040 & R050 in the same order).

Code

//STEP1 EXEC PGM=IEBEDIT
//SYSPRINT DD SYSOUT=A
//SYSUT1 DD DSN=INPUT.PDS(MEMBER),DISP=OLD,KEEP)
//SYSUT2 DD DSN=OUTPUT.FILE,DISP=(NEW,CATLG,DELETE),
// SPACE=(TRK,50,10),RLSE),DCB=RECFM=F,LRECL=80,BLKSIZE=80)
//SYSIN DD *
EDIT TYPE=INCLUDE,STEPNAME=(R010,R020,R030,R050,R040)
/*
//*

Though i have changed the order of job steps in the EDIT statement above, OUTPUT.FILE had the job steps in the same order as it was in the input.

Please correct me if am wrong.

I believe several of the replies to the original poster are not correct. The COND parameter determines whether or not the current step is bypassed or executed based on the result of previous steps or the step named in the COND parameter(s). In other words, if COND=(0,LE) is coded on the 1st step of a job, that step will be bypassed since zero is less than or equal to any previous step. The condition is true in all cases. Since I don't have access to a mainframe, the best way to find out is to test it yourself. It's easy enough to create a test job consisting of a bunch of IEFBR14 job steps. COND evaluations only determine whether the current step is executed. It has no effect on subsequent steps.

From the JCL reference manual:

I stand corrected on that point. Thanks!
