Well, in Vend::Dispatch, it is "$ok" (line 476):

    ($ok, $order_no, $result_hash) = route_order(
                        $::Values->{mv_order_route},
                        $Vend::Items
                        );
    return 1 unless $ok;

In Vend::Order, the route_order() sub returns:

    if($main->{supplant}) {
        return ($status, $::Values->{mv_order_number}, $main);
    }

So it is $status in Vend::Order, but $ok in Vend::Dispatch.

The problem in Vend::Dispatch is that if $ok isn't set, it won't finish
the order, at least to the customer's point of view.
 
Thanks,
