Re: Breaking large Ruby script into multiple files

Following on Jake's advice and noting that you are familiar with Fortran
modules, an easier first step would
be to use modules in Ruby and start from there.

The first.rb from Jake's example could be

module Statistics
  def correlation(a,b)
      # code for correlation
  end

  def stddev(a)
     # code for standard deviation
  end
end

In second.rb, you could do
  require "./first"
  include Statistics  # similar to USE in fortran

 a=[1,2,3,4]
 b=[0,0,0,0]

 correlation(a,b)
 stddev(a)
