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.
