Subject: Re: problem using IRB

Hey, 

I could download it and also use IRB. However, I was wondering if you
could tell me how to run this code on IRB:
def fact(n)
  if n == 0
    1
  else
    n * fact(n-1)
  end
end

print fact(ARGV[0].to_i), "\n"

I tried doing it but its running each line separately. Is there any way
to run the whole thing at once.

Thanks,
Vidhi

Go here:

  http://rubyinstaller.rubyforge.org/

and follow the download link. Download the latest version of the
installer
(182-14). Once you have installed ruby from you should find a number of
use
tools in you start menu under "Ruby", and you should be able to run
"irb"
from the command line to get into an interactive ruby session.
