NAME

worms  −  animate worms on a display terminal

SYNOPSIS

/usr/games/worms [ -field ] [ -length # ] [ -number # ] [ -trail ]

DESCRIPTION

Brian Horn (cithep!bdh) showed me a TOPS-20 program on the DEC-2136 machine called WORM, and suggested that I write a similar program that would run under Unix. I did, and no apologies.

-field makes a "field" for the worm(s) to eat; -trail causes each worm to leave a trail behind it.  You can figure out the rest by yourself. 

FILES

/etc/termcap

MESSAGES

Invalid length
Value not in range  2 ≤ length ≤ 1024

Invalid number of worms
Value not in range  1 ≤ number ≤ 40

TERM: parameter not set
The TERM environment variable is not defined.  Do: setenv term sun if you are using the C-shell csh(1);  or do a: TERM=terminal type
export TERM if you are using the regular Bourne shell sh(1).

Unknown terminal type
Your terminal type (as determined from the TERM environment variable) is not defined in /etc/termcap. 

Terminal not capable of cursor motion
Your terminal is too stupid to run this program.

Out of memory
This should never happen on a Sun.

BUGS

The lower-right-hand character position will not be updated properly on a terminal that wraps at the right margin. 

Worms doesn’t initialize the terminal.
