When using erb (example taken from Programing Ruby):

---------

#!/usr/local/bin/ruby

require 'erb' 

input = %{\ 

<% high.downto(low) do |n| # set high, low externally %> 

<%= n %> green bottles, hanging on the wall 

<%= n %> green bottles, hanging on the wall 

And if one green bottle should accidentally fall 

There'd be <%= n-1 %> green bottles, hanging on the wall 

<% end %> 

} 

high,low = 10, 6 

erb = ERB.new(input) 

erb.run

-----------

I get:

RubyMate r2496 running Ruby v1.8.4.
