This fails all headers. This is expected to be used in conjunction with other hardwire filters to pass headers on to both good and bad output streams. eg
define event_loop call inp call upk call flt($charge_cut) *perform the charge cut if_ok goto good_event call out(3) *output bad events on stream 3 quit_event good_event: call out(2) *output good events on stream 2 call flt($perm_bank_cut) *see if it is a header if_ok quit_event *quit if it is an event call out(3) *output header on stream 3 end_def
