Here's an interesting look at what's wrong with MapInfo's random
number generation function. See longtime MapInfo-Ler Robert
Edwards' piece, "Not-So-Random Numbers" at
http://www.directionsmag.com/article.asp?ArticleID=50.

It clearly shows that MapInfo's random-number generator has got
some weak spots (and ESRI's too, as pointed out in another
article by Bill Huber referenced here.) Just take a look at the
picture of 5,000 "random" points generated by MapInfo's Rnd()
function, and the problem is obvious. It's not even close to a
statistical definition of random!

For you mapbasic fans, he also provides source code to do a
better job of generating random numbers using a "multiple
recursive generator" (MRG) algorithm.
