  NEXTREC = nr

  nr  Is an integer scalar memory reference whose value depends
      on the following conditions:

      - If a record was previously read or written on the
        specified unit, the value of "nr" is one more than the
        number of that record.

      - If no records have been read or written, the value
        of "nr" is 1.

      - If the file is not opened for direct access or if the
        position is indeterminate because of an error condition,
        "nr" is 0.
