The EVENTEXTRA function returns the contents of the tag from the XML text in the EVENT function's second parameter.
Example:
doMyService := FUNCTION
O := OUTPUT('Did a Service for: ' + 'EVENTNAME=' + EVENTNAME);
N := NOTIFY(EVENT('MyServiceComplete',
'<Event><returnTo>FRED</returnTo></Event>'),
EVENTEXTRA('returnTo'));
RETURN WHEN(EVENTEXTRA('returnTo'),ORDERED(O,N));
END;
OUTPUT(doMyService) : WHEN('MyService');
// and a call (in a separate workunit):
NOTIFY('MyService',
'<Event><returnTo>'+ WORKUNIT + '</returnTo></Event>');
WAIT('MyServiceComplete');
OUTPUT('WORKUNIT DONE')
