Hi,
Newbie Question:

How do i invoke a method in belonging to a module?

For Example:

···

###############
#file: SampleModule.rb

Module SampleModule

  def add(a, b)
    return a + b
  end

  def multiply(a, b)
    return a * b
  end

end

################
#file: test.rb

require 'SampleModule.rb'
#here i would like to make a call to add() method of Module SampleModule
(sitting in file: SampleModule.rb)
help??

SampleModule::add(2, 3)

Thanks.

add this lile:
include "SampleModule"

then you can use the add, multiply normally.
