i'm new to pic basic and i'm trying to setup a simple subsumption architecture...
can anyone help with this code :

start:

go_command = command_none
stop_command = empty


if go_command <> command_none then motor_output = go_command
if stop_command <> command_none then motor_output = stop_command

select case motor_output
case stop_command
portb = %00001100
case go_command
portb = %00000011
end select

goto start



basicly i'm just trying to select the correct state based on when go/stop_command(s) are not command_none.

I can't seem to select the second case, go_command, it always just assigns 00001100 to port b

can anyone help

thanks
