I dabbled with this a couple months ago. I found it strange though that null can equal -1 and 0. But setting actual variable to those can be confused with null, thus furthering the complication. I prefer using the '!' (Not) before a var to check to see if it is indeed null. Null is full of lulz but it can be irritating cause of the flawz. z.z
