Does REPRO perform an append to a dataset?

[Atul Mithbhavkar]

Hi,

I'm trying to understand that, if REPRO perform an append to a dataset, in case the ALLOC statement has a MOD? Or should I use IEBGENER?

I verified for all non-VSAM datasets and it is working fine that is there are no error messages. However, when I check to see if the second append to a dataset worked, it looks like the dataset was overridden, rather than appended to.

tested with

submitted THREE times to get

obviously the first submit with an empty output

now the ball is into Your court for researching :geek:
it worked even with more than ONE repro in a single idcams execution

The question is in TSO Part of the Forum, I've not tested it to be sure however ,I think it might be to do with using REPRO in TSO ...!?

Yes, I'm using IDCAMS under TSO and not in batch as enrico has showed. Will that makea difference?
