Re-using VBS code

Last week, I wanted to call VBS file into another VBS file. I wanted similar way in other languages like below.
In C++ -> Header file -> include <*.h>
In VB -> Modules (*.bas)
In Java -> Packages -> import com.myLayer.*

Basically I wanted to make it as a library. I am writing the functions to get the data from Excel and PPT. I have to create separate VBS file for each requirement. Few functions are common for all the VBS files. I got a help from visualbasicscript site. Post: Include VBS file in other files
