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 http://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.
