Indicates that the volume is not in the standard format used by
    the OpenVMS operating system.

    Use the /FOREIGN qualifier when a magnetic tape volume is not
    in the standard ANSI format, or when a disk volume is not in
    Files-11 format.

    If you mount a volume with the /FOREIGN qualifier, the program
    you use to read the volume must be able to process the labels on
    the volume, if any. The OpenVMS operating system does not provide
    an ancillary control process (ACP) to process the volume.

    You must mount DOS-1 and RT-11 volumes with the /FOREIGN
    qualifier and process them with the Exchange utility (EXCHANGE).
    See the OpenVMS Exchange Utility Manual (available on the
    Documentation CD-ROM).

    The default protection applied to foreign volumes is RWLP (Read,
    Write, Logical I/O, Physical I/O) for the system and owner and
    no access for the group and world. If you also specify /GROUP,
    group members are also given RWLP access. If you specify /SYSTEM
    or /SHARE, the group and world are both given RWLP access. Note
    that the /GROUP, /SYSTEM, and /SHARE qualifiers do not alter the
    default protection.

    If you mount a volume currently in Files-11 format with the
    /FOREIGN qualifier, you must have the user privilege VOLPRO,
    or your UIC must match the UIC on the volume.

    The /FOREIGN qualifier is incompatible with the following
    qualifiers: /ACCESSED, /AUTOMATIC, /BIND, /CACHE, /[NO]CONFIRM,
    [NO]COPY, /EXTENSION, /HDR3, /INITIALIZE, /LABEL, /PROCESSOR,
    /QUOTA, /REBUILD, /SHADOW, /OVERRIDE=EXPIRATION, and /WINDOWS.

    Examples

    The following command mounts a foreign magnetic tape on drive
    MTA1:

    $ MOUNT/FOREIGN MTA1: ABCD TAPE

    The following command mounts an RK07 device as a foreign volume
    on DMA2 and assigns the default logical name as DISK$SAVEDISK.
    As a volume that is not file structured, SAVEDISK can be used for
    sequential-disk BACKUP save operations.

    $ MOUNT/FOREIGN DMA2: SAVEDISK
