Sequential Access

On input, any remaining portion of the current record is skipped, and the file is positioned at the beginning of the next record. Two successive slashes (//) skip a whole record.

On output, an end-of-record is written, and a new record is started. Two successive slashes (//) produce a record of no characters. If the file is an internal file, that record is filled with blanks.
