The Modules are the collection of VB statements. Modules are used to simplify the program development. To add a module to your project, choose the project tabpage, and then right click and select add, then select the module. In answer a new dialog will open up.Select new and a new window will open to type your coding. Type the coding which is as shown below:

Sub Main()

Dim sum1 As Integer

sum1 = 80

sum1 = sum1 + 10

MsgBox sum1

Main1

End Sub

Add one more module as Main1. Now type the coding in module Main1which is as shown below:

Sub Main1()

Dim sum1 As Integer

sum1 = 80

sum1 = sum1 - 10

MsgBox sum1

End Sub

You can select the Startup object for the project. Now Select the project tabpage, then right click and choose the properties. Then choose the startup object from the Startup object list box control. In this situation select Main(). Whenever you execute, the Main() will be the initial point of the execution. It displays sum1, and then a call to function Main1 is encountered. Therefore the control gets transferred to the module containing Main1. In the Main1 the subtraction is completed and the value is exhibited.
