My little experience says that it's far better to ensure that any file created has an EOF rather than try to figure this out later. Yup, one easy way to force an EOF is open the file for output, then close it without any write statements. You can also generate an EOF with IEBGENER or SORT.
In days past, simply cataloging a dataset caused the problem of no EOF which in turn caused abends (or running with incorrect data).
With SMS-managed data, an EOF is created automatically when the file is allocated. |
