/sys$common/syshlp/helplib.hlb MONITOR, MONITOR, PROCESSES, Classname Qualifiers, /TOPCPU  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies that a bar graph listing the top CPU time users be
    produced instead of the standard display and summary output.
    Values are expressed in units of clock ticks (10 milliseconds)
    per second.

    Prior to OpenVMS Version 7.3, the MONITOR PROCESSES/TOPCPU
    display showed only a maximum of 8 processes on one screen. In
    OpenVMS Version 7.3, the choice of which one of three screens is
    displayed is determined by the number of CPUs on the system. (See
    the examples in this section.)
