  Sorry, I don't have the code in a form ammenable to e-mail transfer,
  but I do know where a concise algorithm (complete with explanation)
  can be found.  Get a copy of _Numerical_Recipes_in_Pascal_ (sorry,
  don't have the author's names).  The _Numerical_Recipes_ series are
  very popular, (at least here in the U.S.) so you should have no 
  trouble finding a copy.
