OK, help me here.  Here's a small piece of code:
[code]

#!/usr/bin/env ruby

phrase = gets.chomp

l = phrase.length

l.downto(0) {|x|
  print phrase[x,1]
}
#puts
[/code]

Notice that 'puts' on the last line is commented.  If I leave it
commented, nothing will output, if I uncomment it, then my string will
be displayed.  Anyone could enlighten me?
