Hi,
The input file to the SORT step is getting generated in the same JCL. The file is a GDG. I need a SORT step to omit certain records from that GDG. But I do not intend to increase the GDG version number.
I think, I can sort it to a temp dataset and then using REPRO can replace the existing GDG version with temp dataset. |

Terminology is critical in IT, where similar words may mean very different things. Did you mean version here or generation -- there is a huge difference. |

Using the same input file as output is not the greatest of ideas where data integrity is involved.
My suggestion would be to create the input to the sort either as a temporary or permanent file and the create the next GDG generation as output from the sort step. |

Hello,
Strongly suggest you follow Expat's advice.
If you try to re-write the same file, and the sort abends for any reason (x37, timeout, operator cancel, etc), the input will have to be re-created thereby wasting resources.
If you do as Expat suggests, the restart is trivial. |

You already wrote this, so I think you've a solution. However, your subject line gives a different impression and usually I refer to that as "suicidal effort" - which should be avoided. |
