1. It cannot be done "through JCL". JCL does nothing but execute programs.
2. How do you determine if the file has been processed already? If you do not know that, then your question is impossible to answer as stated. |

Thanks,
but i wanted to confirm if we have any utility which we can use in job which can confrim if a perticular version of the file has already been processed through this job. Looking for a utility which can check the version of the file.
Thanks |

| How could that possibly work? You have to code it yourself. Control file, headers, trailers, stuff which should be in the design from day one. |

1) proper scheduling
2) rename the file after use - although I have NEVER seen this done |

If this is an one off case, why dont you check the output file/report of the previous job to see what input got processed? |

There is no such thing. Utilities are not concerned about "version" of a file -- they typically only are concerned with whether or not the file exists. "Version" depends upon the file name, or the header in the file, or the trailer in the file, or some external file that is used to keep track of versions processed. All of this is part of application design and, as such, HAS ABSOLUTELY NOTHING TO DO WITH THE OVERALL SYSTEM. Design the application to track the "version" but don't expect the system to be able to do something magical with your data.
This forum is for professionals. Based upon this question, you would be MUCH better off in Beginners and Students Forum since your question should not even exist in a professional's mind. |

Your question is kinda confusing - are you talking about if the "EOF marker" is set; as in if file is ever opened for processing?  |

If I understand what you are asking I/we did this all the time in one of my previous contracts but not with any specific utility. It worked with a little programming and something like this…
Job 1
1) process incoming daily file from company X.
2) if incoming file processed correctly, add date and time to one-line one-Limit-GDG file.
We wrote the file from a COBOL program.
Job 2 (and other jobs)
If incoming file processed correctly in Job 1, continue Job 2 steps, else stop job.
This was just a simple Easytrieve step to verify the one-line one-Limit-GDG that set a condition-code.
The rest of the JCL steps were executed or not executed depending on condition-code from Easytrieve step. |
