Hi,
if you are using IEBGENER I doubt you are merging but merely copying files into a single output file.
Anyhow I would use the SORT program instead of IEBGENER, it has been discussed many times in this forum, it's by far the quickest of all of the utilities.
Also I would not use IEFBR14 to delete datasets, use IDCAMS, it will not recall migrated dataset to delete them, unlike IEFBR14.
As for the original question see link ibmmainframes.com/viewtopic.php?t=36160&highlight=3273

Thanks Gerry,
You are correct, I want to copy files into a single output file.
I will use SORT but please tell me how many files I can copy to an output file in single step using SORT and how many files I can delete using IDCAMS? |

| Why not try it yourself and let us know what, if any, errors you encounter |

| If you don't have access to a mainframe, maybe the manuals have your answers. Have you looked there? |

So how many files are there you want to deal with? |

Hello,

Usually, requests for "maximums" are not the real issue/requirement anyway.
Suggest you post what you actually need to accomplish (i.e need to copy 538 files into a single output file and then delete them). You might also mention if these files all have the samne attributes (recfm/lrecl) or not.
If you post more info about what you want to do, someone should be able to post a more useful reply. |

The maximum number of DD statements per job step is 3273,
based on the number of single DD statements allowed for a
TIOT (task input output table) control block size of 64K.
This limit can be different depending on the
installation-defined TIOT size. The IBM-supplied default
TIOT size is 32K. |
