Does it really make that much difference? The most important difference IMHO is, that you will get reproducable node counts independent of platform and/or compiler used. If you "only" want to use Visual Basic, this might not be a problem. At least not, when in a new version the random number generator will never be changed. I use the hash-keys also for accessing the book. The Linux-version of my engine would need a different book, if I would use compiler specific rand(). With a self coded RNG, this is not a problem (although, I have to admit, that I would need a new book on a big endian architecture. I was too lazy to fix this). Regards, Dieter
