How-to SLUG.BAS:

This program gamesmasters a game of SLIMETRAIL (see
http://www.gamecabinet/rules/Slimetrail.html
).  It asks for co-ordinates.
To the first question, answer 1,1
to the second question, answer with board-size figures up to
about 30 by 17 (a definite maximum).
Then, enter the starting co-ordinates of the SLUG.
the screen will clear, and be replaced with a gameboard.
The title will be on 25th line of screen.
the square in upper left corner will be blue
the square in lower right corner will be purple
These squares will be goals for the two players.

Press [SPACE].  The slug appears.  A small coloured square
in his/her upper left corner shows who's turn it is.  Press
[SPACE] to pass your turn.

Keys to move the slug:
 w    i    8
asd  jkl  456
These keys move the slug in the standard ordinal directions.
The Slime-Trail is automatically drawn on the screen.

When you finish a game, the slug must be put back where it came
from and the table wiped clean.  Do this by pressing the 'c' key
(c is for Clear) twice.  You can press [SPACE] until the desired
player has the first turn.

The only way to quit the game is by pressing the CTRL-BREAK keys.
I did not think that writing the code to allow for an easy exit
was worthwhile, as my implementation is so rough anyway.  If you
like the game, please enjoy it as much as you can and teach it to
your friends.  It can also be played with other move systems (king
from chess or knight), or you can play on boards that are not made
of squares (like a Hex set).  All of the information on these other
variations is on the official game page - I hope that this (weak)
program inspires you to write better ones.  I am still using it to
play games against my friends.  Perhaps for more fun there could be
a three-player game played on a triangular board, but how could it
be written?  A worthy challenge for a brave code warrior!
