/FILTER=(event-code,...)
  /NOFILTER

 	Specifies a filter for trace records.

 	A trace record is displayed only if its event code is one of
 	those specified in the filter. This value overrides the
 	current filter, if any.

 	You cannot specify this qualifier with /SELECT or
 	/TRACE_LEVEL.

 	The default is /NOFILTER.
