Hello GS, Thursday, February 08, 2001, 2:56:49 PM, you wrote: GJ> I know "zip" about random number generators, but I just happened to run GJ> across this site (was it a "random" coincidence??? :-).

GJ> By the way, you could use a truly random nondeterministic number generator from Intel, called Intel RNG and implemented in all of its modern chipsets: i810, 1815, 820, 840, and so on... More information is available at and in Intel 82802 Firmware Hub: Random Number Generator Programmer's Reference Manual December 1999 Order Number: 298029-001 R But I don't know if it's possible to access it from Rebol ;-) GJ> --Cheers
