When I was a child, we had a Compaq 286 computer with a green-and-black screen. It didn’t have a mouse, of course; instead, you had to type commands for everything. There were still games for computers in those days, and I loved playing them. With the help of a book of 100 games, in second grade I started writing my own in BASIC, one of the earlier programming languages. I would type the game codes into the computer, run the program, and play the game.
