I've got a vexing problem that could probably use the collected
wisdom assembled here :-)
I want to open a sequential (non-PDS/PDSE, non-HFS) fixed block
file for output, POINT to a particular TTR and write a record
without truncating the file. This is all BSAM I/O.
The documentation is very clear that opening for OUTPUT,
and POINTING truncates the file - but that means I loose data.
Opening the file for UPDAT would seem like a reasonable thing
to do, but I may be extending the file, or altering blocks/records
in-the-middle. So, that probably won't work either.
Any thoughts?
- Thanks! -
