     _R_a_n_d uses a multiplicative congruential random number gen-
     erator with period 2**32 to return successive pseudo-random
     numbers in the range from 0 to (2**31)-1

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