So how do you pass parameters to your Fortran program - in a config file 
perhaps? If so, then just generate that file then run the program. It's 
up to you to code what you want.

Does it read a flat file? XML? YAML? Something else?

class FlatFileRunner
  def initialize(exe, conffile)
    @exe, @conffile = exe, conffile
  end
  def run(params = {})
    File.open(@conffile, "w") do |f|
      params.each do |k,v|
        f.puts "#{k}=#{v}"
      end
    end
    %x{"#{@exe}"}
  end
end

prog = FlatFileRunner.new("./flurble", "./flurble.conf")
res = prog.run("foo"=>123)
puts "Result of experiment: #{res}"
