1 REGISTER_NODE_INFORMATION
!
This function adds a node registration to a directory service, or modifies
a current node registration.  

When the node name is entered, it is checked to see if it already exists
in the directory service.  If it does not yet exist, a message is
displayed indicating that a new node is being registered.  This feature
is used when a new node is made available in the network, and the node
registration needs to be added to a directory service to allow lookup by
other nodes.

If the node name already exists, a message is displayed indicating that
the node name is being modified, and the currently registered values are
read and presented as inout defaults.  
!
2 Directory_Service
!
This field specifies the directory service that contains the node
registration to be shown.  The service must be one of:

    LOCAL
    DECDNS
    PHASEIV

The service type can be abbreviated, as long as the abbreviation is
unique.
!
2 Node_Name
!
This field specifies the name of the nodes to be registered or modified.
This must be the fully specified name for the node in the directory
service.

The syntax of a fully specified name depends on the directory service
being used.  Examples of fully specified names might be:

    For Local:      MailHub
    For DECdns:     MyCo:.Sales.MailHub
    For Phase IV:   MLHUB
!
2 Synonym
!
This field specifies the Phase IV synonym for the node.  Phase IV
synonyms can be used in place of fully specified node names,
particularly with applications that do not support full node names.

The synonym must be from 1 to 6 letters (A to Z) or digits (0 to 9),
with at least one letter.  If the field is left blank, a synonym name
is not registered for the node.
!
2 Address_Towers
!
This field allows you to indicate how you want to handle the address
towers for the node registration.  You can enter one of the following
keywords.  These can be abbreviated, as long as the abbreviation is
unique.

  Modify    - Modify the current address towers.

              If the node is being registered, this allows you to enter
              new address towers.

              If the node is being modified, the old towers are presented
              as defaults, and you can change, add, or delete address
              tower information.

  Keep      - Keep the current address towers.

              If the node is being registered, it has no current towers.
              Use this to indicate that no towers are to be registered
              for the node.

              If the node is being modified, the current address towers
              remain unchanged.

  Replace   - Replace the current address towers.

              If the node is being registered, this allows you to enter
              new address towers (this is equivalent to modify).

              If the node is being modified, the current towers are
              deleted, and you are asked for a new set of towers to be
              registered for the node.

  Delete    - Delete the current address towers.

              If the node is being registered, it has no current towers.
              This indicates that no towers are to be registered for
              the node (this is equivalent to keep).

              If the node is being modified, the current towers are
              deleted.  You are not asked for a new set of towers.

If you answer replace or modify, another form is brought up to allow
you to enter the address tower information.

If you answer keep or delete, you are asked if the node should be
registered or modified.  You can proceed or cancel the operation at
this time.
