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!
