Hello, Nathalie and everyone!

Another question. I have some numerical recipies for pascal downloaded from a website but I don't have the program for a beta distribution. Is someone got it?

I do not quite understand what you mean. Beta and alpha distributions of GNU Pascal can be found at:

ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/

But you are probably asking for something different ... :-]
