NAME

worms  −  animate worms on a display terminal

SYNOPSIS

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.

DIAGNOSTICS

Invalid length
Value not in range  2 <= length <= 1024 Invalid number of worms

export TERM 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 VAX. 

BUGS

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

Terminal initialization is not performed. 

There should be an option to have the worms eat Pink Floyd lyrics.
