If it is a network ; write error, it's not logged to the Error Trap ; Set Process Name crashed on Cache due to undefined IO("GT.M"). ; Now this is surrounded by $Get to prevent this error. ; 6/25/2011: Fix to error trapping introduced by last patch. ; Having N $ETRAP before setting $ETRAP as the backup trap causes ; an infinite loop because of the restoration of the old trap ; which lead it there in the first place.
