Hi,
I have a issue.
there are several step in my JCL. just think that there are 5 steps
step1
step2
step3
step4
step5
Step2 is having the empty input file.
Requirement is:
If the input file is empty, the step2 should not execute and the remaining steps should execute.
i am able to do the above. but the another issue is, even though if i bypass, the job return code should be zero. i am struck up with this issue.
Please help me on this. |

| Use the JOBRC parameter for your job. |

Hi Superk,
Thanks for the suggestion.
Is there any possibility to set JOBRC, based on condition(IF) in JCL using IDCAMS?
i know that there is no possibility to set JOBRC based on condition in JCL.Please let me know, if i am wrong. |

There are multiple ways you can achieve this...
Using ICE TOOL...
| Code: |
// EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//INFILE DD DSN=XXX.YYY.ZZZ,DISP=SHR
//TOOLIN DD *
COUNT FROM(INFILE) EMPTY
/* |
RC=12, tells us.. given file is empty.
Using IDCAMS.
| Code: |
//CHECKING EXEC PGM=IDCAMS
//INFILE DD DSN=XXX.YYY.ZZZ,DISP=SHR
//SYSIN DD *
PRINT INFILE(INFILE) COUNT(1)
IF LASTCC NE 0 THEN SET LASTCC = 12
/* |
RC=12, tells us.... given file is empty.
And then you can use IF conditions accordingly in further steps which all you want to bypass. |

Hi Rohit,
as per my knowledge, we can set only that perticular step return code using IDCAMS and ICETOOL. we cann't change the already completed step return code. |

| Seems to me that the program logic of step2 needs to amended to be able to deal with an empty file.. |

Hello,

Correct - once a step completes, the return code (completion code) cannot be changed.
As Expat mentioned, the process of step2 needs to be aware of the situation and set the return code accordingly. The rest of the steps would check the COND to run or skip. |

These two statements contradict each other and your meaning is unclear. What Kevin suggested is exactly what you need provided you have the latest versionof z/OS which is when JOBRC was introduced. Note that this should only be a temporary solution until you get you program that cannot handle an empty file fixed. |
