call processor
call processor(arg1,arg2,...)
goto label
continue
quit_event
quit_job
call out(1,2,3)  * Output on streams 1, 2 & 3
Note that:-
The standard course of action after a processor call is to quit the event if an error occurred, unless the processor was a fitter, classifier or filter. In such cases, an error is not considered fatal. This default behaviour can be overidden if the call is followed immediately by a conditional command, thus allowing the user to gain full control:-
  call mco
  if_not_ok continue     * Don't quit if MC error 
                         *      (a strange request!)
  call ftt
  if_not_ok quit_event   * Fit failed
