      In this example, the DUMP command dumps the file header of the
      specified file. Because this file is recorded on Files-11 ODS-2
      9660 media, the file header is displayed in a Files-11 File
      Header format. Imbedded on the Files-11 Header is a VAX RMS
      attributes block.

      The DUMP/HEADER command dumps the file header of the specified
      file. Because this file is recorded on ISO 9660 media, the file
      header is displayed in the format of an ISO 9660 File Header
      and, since this file contains an optional ISO 9660 Extended
      Attribute Record (XAR), it is also displayed. Finally, as with
      all DUMP/HEADER requests, VAX RMS attributes are displayed.
