Creates a Routing Circuit Adjacency entity for particular circuit you
    have selected.  A Routing Circuit Adjacency entity describes a
    neighboring node that is accessible through a particular circuit.

    The required arguments for this display are:

    o   Name

        The simple name to be assigned to the adjacency.

    o   Endnode IDs

        A set of source system IDs.  To add new Endnode IDs to this set,
        type the Endnode ID in the "End Node IDs to Add" field and push the
        ADD button.  To remove old Endnode IDs from this set, click on the
        Endnode ID you wish to remove so that it becomes highlighted, then
        push the REMOVE button.  A scroll bar will appear to the right of
        the Endnode IDs field whenever it is necessary to allow you to move
        through the list of Endnode IDs.

    o   LAN address

        The Data Link address from which the adjacency receives end
        system hellos.

    The optional argument is:

    o   Data Format

        This string describes the format of the reachable address.

    Press the CONTINUE button to create the Routing Circuit Adjacency entity,
    or press the CANCEL button to cancel this operation.  In either case, you
    will return to the main window.
