   The "linear congruential" method typically involves an addition as well as
a multiplication (using modular arithmetic).
   My docs say that R(n+1) = [R(n) * a] + b using fixed-length (presumably
long) operations to make everything mod 2^32 or whatever.  FYI, a = 3141592621
and b = 1.  In addition, the OS call returns R(n+1)>>8, which gives a
24-bit pseudorandom number.
