I'm trying to use the `random` command in PBASIC and I'm not sure how it works. I'm using a PICAXE-08 Proto Board Kit, and the chip specifically is a PICAXE-08M2. 

Here is the code I'm using:

```
symbol randnum = w0
RANDOM randnum
randnum = randnum // 2

FOR action = 1 TO 5
    IF randnum > 0 THEN
        LOW led_red
        PAUSE 500
        HIGH led_red
        PAUSE 500
    ELSE
        SOUND buzzer,(100, 100)
        PAUSE 500
    ENDIF
NEXT action

```

(Perhaps due to assembly mistakes, the LED's HIGH corresponds to LOW and vice-versa). 

First of all, I expected to put the `RANDOM randnum` command within the for loop, but if I do this, the loop count becomes incorrect. Instead of 5 actions, I get only 2. 

The second problem is that I'm expecting `randnum` to be either 0 or 1, so that 50% of the time the LED is lit and 50% of the time the buzzer sounds. However, the LED is lighting 100% of the time, even across multiple trials. Obviously, `randnum` is never 0. However, according to [documentation](http://www.picaxe.com/BASIC-Commands/Variables/random/), `RANDOM` should give the variable a value between 0 and 65535, inclusive. 

What is the issue here?
