        !            21: .it Rand
        !            22: uses a multiplicative congruential
        !            23: random number generator to return successive pseudo-random
        !            24: numbers (in r0) in the range from 1 to 2\u\s715\s10\d\*-1.
        !            25: .s3
        !            26: The generator is reinitialized by calling
        !            27: .it srand
        !            28: with 1 as argument (in r0).
        !            29: It can be set to a random starting point by calling
        !            30: .it srand
        !            31: with whatever you like as argument,
        !            32: for example the low-order word
        !            33: of the time.
        !            34: .sh WARNING
        !            35: The author of this routine has been writing
        !            36: random-number generators for many years and has never been
        !            37: known to write one that worked.
        !            38: .sh BUGS
        !            39: The low-order bits are not very random.
