Publisher's blurb Cup is a cute little game in which a cup is located thirty "Y" coordinates down the video display and a random number of spaces from one to sixty to the right of the left margin. The pull of gravity varies from one to ten lines per second per second. You are then asked in this program what push you would like to give the ball from left to right across the paper in spaces per second. The program then traces the path of the ball from the left margin of the paper as it falls down and hopefully into the Cup.
