worm - play the growing worm game
worm [ size ]
In worm, you are a little worm, your body is the "o"'s on
the screen and your head is the "@". You move with the
hjkl keys (as in the game snake). If you don't press any
keys, you continue in the direction you last moved. The
upper case HJKL keys move you as if you had pressed sev-
eral (9 for HL and 5 for JK) of the corresponding lower
case key (unless you run into a digit, then it stops).
On the screen you will see a digit, if your worm eats the
digit is will grow longer, the actual amount longer
depends on which digit it was that you ate. The object of
the game is to see how long you can make the worm grow.
The game ends when the worm runs into either the sides of
the screen, or itself. The current score (how much the
worm has grown) is kept in the upper left corner of the
The optional argument, if present, is the initial length
of the worm.
If the initial length of the worm is set to less than one
or more than 75, various strange things happen.
