NAME

     rand - random number generator



SYNOPSIS

     (seed in r0)

     jsr     pc,srand        /to initialize



     jsr     pc,rand /to get a random number



     srand(seed)

     int seed;



     rand( )





DESCRIPTION

     Rand  uses  a  multiplicative  congruential  random   number

     generator to return successive pseudo-random numbers (in r0)
                             15
     in the range from 0 to 2  -1.



     The generator is reinitialized by calling srand  with  1  as

     argument  (in r0).  It can be set to a random starting point

     by calling srand with whatever you  like  as  argument,  for

     example the low-order word of the time.



BUGS

     The low-order bits are not very random.
