p On the screen you will see a digit. If your worm eats the digit it will grow longer by that number of "o"'s, scaled to screen size. The object of the game is to see how long you can make the worm grow.
p The game ends when the worm runs into either the sides of the screen or itself. The current score
q how much the worm has grown is kept in the upper right corner of the screen.
p The optional argument, .Ar size , is the initial length of the worm's body. The specified length will be rejected if it causes the worm to cover more than roughly one third of the screen.
