While I was learning BASIC programming on my Vic-20, every month I would read several of the early computer magazines such as Byte Magazine. I remember one particular review that I read; it was for a game called Zork. While Zork was not a game that was available for my Vic-20, the concept of the game fascinated me because I was really into sci-fi and fantasy. I remember thinking how cool it would be to write a game like that, so I decided to figure out how to do it. One of the biggest concepts that I had to grasp at that time was controlling the flow of the application depending on the user's actions.
