A82: Re: Squares and random numbers
Hey, thanks. That's just what I was looking for. If that code doesn't
work I'm sure I can fix it. It'll help me to learn how it works better
anyway. Any idea when Ash3.1 will be available? A random number
generator would be a really useful feature for any programmer. Thanks
for the help!
