Explanation

For REWRITE to work successfully, the file must be opened in I-O mode. INPUT mode only allows reading, OUTPUT mode is for creating new files, and I-O mode allows both reading and updating existing records. REWRITE modifies an existing record, so it requires the update capability provided by I-O mode.
