Specifies a continuously updating display. If you omit the
    qualifier, SHOW CLUSTER produces a single display and returns
    control to the DCL command level.

    Running SHOW CLUSTER in the continuous mode allows you to use
    SHOW CLUSTER commands to control the display. In a continuous
    display, you can control report output with SHOW CLUSTER
    commands. For information about the SHOW CLUSTER commands, invoke
    a continuous SHOW CLUSTER display and type HELP at the Command>
    prompt.

    SHOW CLUSTER has commands that allow you to customize the
    display. You can add and remove fields and classes, rearrange
    the position of windows, scroll their contents, or create
    an initialization or command procedure that can recreate a
    particular window setup.

    To exit from a continuous display and return to the DCL level,
    type the EXIT command or press Ctrl/Z.

    To exit from SHOW CLUSTER without erasing the screen, press
    Ctrl/C.

    To interrupt SHOW CLUSTER, press Ctrl/Y.

    For a complete description of the Show Cluster utility and
    commands, see the VSI OpenVMS System Manager's Manual for overview
    information and the VSI OpenVMS System Management Utilities
    Reference Manual for reference information.
