VMS Help SHOW, SYSTEM, Qualifiers, /PROCESS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PROCESS[=name] (default)
       /NOPROCESS

    Displays all specified processes on the system. If you do not
    specify a process name with the /PROCESS qualifier, all processes
    are displayed.

    When you use the /NOPROCESS qualifier with the /CLUSTER
    qualifier, only the node or nodes available on the cluster are
    displayed with their respective uptimes and operating system
    version.

    You can include the asterisk (*)  and the percent sign (%)
    wildcard characters in the process name.
