- - Ah ha, at last some code. First of all there is a huge code
  smell here. You are writing Fortran in Ruby. NO method/function
  in any language that supports data structures should have more 
  than 3 parameters. ( well maybe 4 in extreme cases.) Certainly,
  in a Ruby method, more than 3 args is suspcicious. 

- - Maybe you'd get a lot more out of Ruby if you spent some time
  refactoring your code. I'd start out by making link an object
  rather than a method. It's no wonder you want types in Ruby,
  types would be a great addition to Fortran.
