You can use the “if” keyword (and a whole bunch of brackets!) to do different things based on a question. So lets say you have an input W that is the distance away a player is (reported by a [[Scanner Block|scanner block]]) and if the player is closer than 5 meters away you want to show on a screen (connected to N) “Go away” and raise a door (a [[Rail Block|Rail block]] connected to S) but if they do go away reopen the door you could use this program:

<pre>if(W<5){        // W is the distance away the player is
  N = 'Go away!'
  S = 4         //S is connected to a rail set to position mode, 4 is fully closed
}else{
  S = 1         //position 1 is fully open   
}
</pre>
