basically what this means is that relays 1 through 4 are the 8 bits in relayA. relays 5 through 8 are the 8 bits in relayB. This isn't something that should concern you to badly. The important part is...
relay1_fwd = p1_sw_trig &~ rc_sw1 'Port 1 Trigger = Relay 1 Forward 'Relay 1 wont go Forward if rc_sw1 is ON
relay1_rev = p1_sw_top &~ rc_sw2 'Port 1 Thumb = Relay 1 Reverse 'Relay 1 wont go Reverse if rc_sw2 is ON
relay2_fwd = p2_sw_trig &~ rc_sw3 'Port 2 Trigger = Relay 2 Forward 'Relay 2 wont go Forward if rc_sw3 is ON
relay2_rev = p2_sw_top &~ rc_sw4 'Port 2 Thumb = Relay 2 Reverse 'Relay 2 wont go Reverse if rc_sw4 is ON
relay3_fwd = p3_sw_trig 'Port 3 Trigger = Relay 3 Forward
relay3_rev = p3_sw_top 'Port 3 Thumb = Relay 3 Reverse
relay4_fwd = p4_sw_trig 'Port 4 Trigger = Relay 4 Forward
