1 SET
!
Modify the default values for optional parameters.

    SET DEFAULT
        [ DIRECTORY_SERVICE dir-service ]
        [ DISPLAY_MODE display-mode ]
        [ NSAP_FORMAT format ]
        [ PHASEIV_PREFIX addr-prefix ]
        [ REVERSE_DIRECTORY rev-dir-name ]
        [ SYNONYM_DIRECTORY syn-dir-name ]

This provides a means to preset the values for commonly used parameters,
such as the reverse address mapping directory name to use for a particular
directory service.

This is particularly useful when done in a DECNET_REGISTER initialization
command file (see "HELP USAGE INITIALIZATION_COMMAND_FILE").
!
2 DEFAULT
!
This keywork is required.  It indicates that default parameter values
are being modified.

See the SET topic for a general description of the SET DEFAULT command.
!
2 DIRECTORY_SERVICE
!
This specifies the directory service to use as the default, when the
command does not specify a directory service.

    DIRECTORY_SERVICE dir-service

The service must be one of:

    DIRECTORY_SERVICE LOCAL
    DIRECTORY_SERVICE DECDNS
    DIRECTORY_SERVICE PHASEIV

If other parameters are specified in the command, this also determines
the directory service that those additional default value parameters
apply to.  For example:

    SET DEFAULT DIRECTORY_SERVICE DECdns REVERSE_DIR .DNA_BackTranslation
!
2 DISPLAY_MODE
!
This specifies the default display mode to use when the mode is not
explicitly requested in the command.  The following display modes are
provided.

    DISPLAY_MODE NAMES     Display only the names
    DISPLAY_MODE BRIEF     Display names and addresses
    DISPLAY_MODE FULL      Display and error check all information

For example:

    SET DEFAULT DISPLAY_MODE FULL

See the SHOW DISPLAY-MODE topic for more information on each mode.
!
2 NSAP_FORMAT
!
This specifies the default NSAP display format to use when the format is
not explicitly requested in the command.  The following display formats
are provided.

    NSAP_FORMAT DNA       Use DNA format
    NSAP_FORMAT OSI       Use OSI format

For example:

    SET DEFAULT NSAP_FORMAT OSI

See the SHOW NSAP_FORMAT topic for more information on these display
formats.
!
2 PHASEIV_PREFIX
!
This specifies the default AFI, IDI, and preDSP to use when constructing
an NSAP from a Phase IV address.  This is used when a Phase IV address
is specified in an address tower, and an explicit Phase IV prefix is not
specified.

    PHASEIV_PREFIX addr-prefix

For example:

    SET DEFAULT PHASEIV_PREFIX 39:840:800AB738

See the PHASE_IV_PREFIXES topic for details about Phase IV prefix
values.
!
2 REVERSE_DIRECTORY
!
This specifies the default base directory or name entry to use for the
reverse address mapping links to the node name (also called the back
translation links).

    REVERSE_DIRECTORY rev-dir-name

The links under this directory are used to map NSAP values to their
respective node names.  These directories are used only for the DECdns
directory service.

For example:

    SET DEFAULT DIRECTORY_SERVICE DECDNS REVERSE_DIR .DNA_BackTranslation

For more information, please refer to the NAMES_AND_DIRECTORIES topic.
!
2 SYNONYM_DIRECTORY
!
This specifies the default base directory or name entry to use for the
synonym mapping link to the node name.

    SYNONYM_DIRECTORY syn-dir-name

The links under this directory are used to map Phase IV synonyms to
their respective node names.  These directories are used only for the
DECdns directory service.

For example:

    SET DEFAULT DIRECTORY_SERVICE DECDNS SYNONYM_DIR .DNA_NodeSynonym

For more information, please refer to the NAMES_AND_DIRECTORIES topic.
