In this tutorial, we cover how to create a module, store information inside a module and then access that information in your application. A module can be used to store functions, subs or even variables to sort out your code so that you can access things more easily. If you have a sophisticated application where you have to store a lot of functions, subs or variables then it would be useful to sort them into different categories using modules. A module is differen t to a class because all of the members of a module are shared and a module does not have a consutrctor, meaning you can not create an instance of a module.
