Subject: Re: Infinate Loop - Please Advise

Sorry, here's a better working example. I wrote the others quickly in  
irb. The trouble with irb is that it isn't the most graceful  
environment for writing nested conditions or loops or elements. It's  
possible, but easy to make mistakes. Anyway, the white space in the  
conditionals and looping constructs is pretty important to Ruby.

beer = 99
beer.downto(1) do |cerveza|
   puts "#{cerveza} bottles of beer on the wall,"
   puts "#{cerveza} bottles of beer..."
   puts "take one down pass it around..."
   if cerveza > 1
     puts "#{cerveza - 1} bottles of beer on the wall"
   else
     puts "no mas cerveza..."
   end
end
