/EVENT=(event1,event2,...)

    Enables trace display of specific events.  The default is all events.
    Event names are displayed by the PE TRACE/CONTEXT command.  Each
    event name may be preceded by "NO" to exclude the event.

    /EVENT=ALL includes all events.  /EVENT=(ALL,NOEVENTn) includes all
    events except EVENTn.  /EVENT=EVENTn (equivalent to (NOALL,EVENTn)
    selects only EVENTn.
