Cycle=seconds
    Nocycle

    Directs the Performance Monitor to continually cycle through the
    set of screens associated with the currently selected menu item.
    Each menu is displayed for the number of seconds specified.

    When you specify the Cycle qualifier, you can change screen
    modes or change submenus as desired; cycling through the menus
    associated with your choice continues at whichever menu level is
    currently selected.

    The specified value for the Cycle qualifier must be greater
    than or equal to the value specified for the Time qualifier.
    In addition, if you manually change the refresh rate (using the
    Set_rate onscreen menu option) to a value that is greater than
    the value you specify with the Cycle qualifier, the cycling is
    performed at the interval you specify for the Set_rate.

    If you do not specify the Cycle qualifier, or if you do not
    specify the number of seconds, no screen cycling is performed.
