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??

this seems to work:  
SampleModule::add(2, 3)  
so i think i’m ok for now.

Thanks.

add this lile:  
include “SampleModule”

then you can use the add, multiply normally.
