    Shows the backtranslation softlink subentities in the session control
    database on the specified node.  If the node is using the DECdns
    directory service, then such one softlink subentity should exist for
    each DECnet address held by the node.  (Softlinks are NOT created for
    cluster alias addresses.)  If an OpenVMS node is configured to run
    DECnet over IP and is using the DECdns namespace, then one softlink
    subentity should exist for each non-zero IP address as well.

    Softlinks in the DECdns namespace are used by all nodes in the
    namespace to associate a particular address with a nodename
    (DNS$LinkTarget).  Therefore, if a node's backtranslation softlinks
    are not properly configured within a DECdns namespace, then other
    nodes using that namespace will not be able to associate that address
    with correct nodename.

    NCL can be used to show what softlinks the node can be configured
    to maintain in the specified DECdns namespace.  If the session control
    attribute maintain backward softlinks is true, then the node will
    periodically attempt to update its softlinks in the DECdns namespace.

    If the NCL SHOW command indicates a high Update Failure rate, the
    Last Failure Reason may suggest the reason for the failure. You may
    then use the DNS$CONTROL and DECNET_REGISTER tools to troubleshoot.
    These tools can be used to confirm that a DECdns server is accessible
    and that the DECdns namespace contains the proper object and
    softlinks for this node.

    Examples:

    show node WINTER:.XPR.CASE session control backtrans softlink * all
         ! Shows all softlinks contained in the session control
         !  database of node WINTER:.XPR.CASE.

    show session control backtranslation softlink -
         WINTER:.DNA_BACKTRANSLATION.%X49.%X0018.%XAA0004002A60 all
         ! Shows a softlink contained in the session control database
         !  for the local node.  It indicates that the node is the
         !  holder of DECnet address 24.42 within the WINTER namespace.

    show session control backtranslation softlink -
         WINTER:.DNA_BACKTRANSLATION.%XA1725E45 all
         ! This softlink indicates that the local node is configured
         !  as the holder of the IP address 161.114.94.69 in the
         !  WINTER namespace. (IP softlinks are on OpenVMS only)
