With respect, Alan. A V-format file is truncated if you overwrite a record with a longer one. You can replace records in place without truncation as long as you adhere to this length restriction.

You can update a file starting with any record you want, but when you're done, V-format files will move EOF to after the last record you write. For F-format files, EOF doesn't move unless you add records.
