it sounds like you are talking about importing... you can write functions,
classes, modules, etc, in one file and access them quite easily from
another, using the 'require' keyword. Use the word 'require', followed by
the name of the file you want to include. you only need the prefix of the
file, (you leave off the .rb part) and you surround the name with single
quotes.

file1.rb

class MyClass1
  def myfunc1
    puts "function1 called!"
  end
end

----
file2.rb

require 'file1'

a = MyClass1.new
a.myfunc1
