Cheers.

I did manage to write a program which simulates Gamma and Beta rv's. 

There's one hitch with it at the moment. The process it iterative, requiring the calculation of some pretty miniscule values. 

When I run, (using long doubles) the values- apparently- get re-set to zero as soon as they fall below ~ 1e-324. I thought that long doubles could handle much smaller values than this- am I missing something?

Thanks-

David R

Check out GSL, the GNU Scientific Library.
I had a link for GSL for djgpp on my other
computer, I'll see if I can hunt it up
again..
