NAME

     worms -- animate worms on a display terminal


SYNOPSIS

     worms [-CfHrt] [-d delay] [-l length] [-n number] [-S seed]


DESCRIPTION

     worms is a UNIX version of the DEC-2136 program ``worms''.

     The options are as follows:

     Use colours, if available, to make the worms easier to distinguish.

     Specifies a delay, in milliseconds, between each update.  This is useful
     for fast terminals.  Reasonable values are around 20-200; the default is
     20.

     Makes a ``field'' for the worm(s) to eat.

     Display the head of the worm differently than its body.

     Specifies the length of each worm; the default is 16, the minimum is 2.
     In the second form, worm lengths are randomly chosen between min (which
     must be at least 2) and max.  The max worm length will be reduced if
     required by the screen size and the number of worms selected.  This
     option overrides any earlier -r.

     Specifies the number of worms; the default is 3.  There must be at least
     one.

     Use random lengths for the worms, within a range of sizes chosen to suit
     the screen size.  Note this option overrides any earlier -l.

     Provide an integer seed for the random number generator.  Specifying zero
     (0, the default) causes a random seed to be used.

     Makes each worm leave a trail behind it.

   The maximum length, and number, of worms depends upon the screen size,
   though the length can never exceed 1024.  If the screen is particularly
   small, even the defaults for those may be too large.  Screens with less
   than 3 rows or columns cannot be handled, nor can ones with insufficient
   total space.
