Ruby is a nice and expressive language. Now my favourite Ruby site is http://whytheluckystiff.net/articles/2003/08/04/rubyOneEightOh I have a query about Ruby 1) Like Python can I increase the maximum depth of Ruby Interpreter Stack? This will help to calculate factorial(1000) recursively. Without increasing the recursion limit, it will not possible to calculate factorial(1000) recursively with Ruby 1.8 (Win 98). It is possible to do the same with Python. Regards, Srijit
