     NAME
          rand, srand - random number generator

     SYNOPSIS
          srand(seed)
          int seed;

          rand( )

     DESCRIPTION
          Rand uses a multiplicative congruential random number gener-
          ator with period 232 to return successive pseudo-random num-
          bers in the range from 0 to 215-1.

          The generator is reinitialized by calling srand with 1 as
          argument.  It can be set to a random starting point by call-
          ing srand with whatever you like as argument.
