RT aren't really to blame: random number generation is an arcane art that a lot of books and courses tend to cover badly. Very few people realise that the algorithm suggested by ANSI is flawed simply because it's the standard - it must be safe. They implemnt it or a variation of it because it's easily available, widely used and seldom criticised outside scientific software circles.

I wouldn't say I'm an expert, but I have quite a lot of experience in writing them. If you want a good introduction, Numerical Recipies in C has a good chapter on random number generation. I will probably implement a subtractive method generator tonight and post the code to the list anyway... Chris -- New sig in the works Explorer2260 Designer and Coder
