Subject: Re: Adding data to text file variables

Thanks for your prompt reply. Can I run over a few bits of the code you 
send across?

> template = ERB.new(File.read("template.erb"), nil, "%<>")

What does the above line of code, do? What is the erb file?

> File.open("result.txt", "w") do |f|
>    f.puts template.result(binding)
> end

This makes no reference to the variables, so how are they written to the 
text file?

Many thanks
