Subject: Re: Recursion help.

Done! Works great, but I am always interested in seeing how it can be
better. Less code, cleaner, faster sort of thing. Here it is, if
anyone has any ideas on how I can make it better, please do tell.

puts "Enter file name"
filename = gets.chomp

puts "Enter carton size"
carton_size = gets.chomp

puts "Enter header description"
description = gets.chomp

out_file = File.new("C:/test/#{description}.xls", "w+")
out_file.write("#{description}\n")
out_file.write("Carton number \t Carton quantity \t Card number \n")

file_size = IO.readlines(filename).size
total_cartons = (file_size.to_f / carton_size.to_f).ceil
i = 0
sequence = 1

in_file = File.open(filename)

until in_file.eof?

  (i..(carton_size.to_i - 1)).each do |number|
    if in_file.eof?
      in_file.close
      out_file.close
      puts "Done!"
      exit
    end
    record = in_file.readline
    out_file.write("#{sequence}\t#{total_cartons}\t#{record[7, 19]}
\n")
  end

  sequence += 1
end
