Can you change it so that it isn't a sequential file?
Otherwise you are out of luck.
Also, be aware the issuing the WRITE does not guarantee that the record is
firmed to disk, especially when there is an abend. The record may be in a
buffer. A CLOSE will force the write. There may be other tools provided by
your COBOL.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.
I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
