Understanding the Difference between Function and Subroutine in VBScript

When it comes to VBScript programming, it is crucial to grasp the distinction between a function and a subroutine. The primary difference lies in their return values:

Function

A function in VBScript is a block of code that performs a specific task and returns a value. It is invoked by using its name followed by parentheses. Functions are commonly used to perform calculations or operations and return a result that can be stored in a variable.

Subroutine

On the other hand, a subroutine, also known as a procedure, is a block of code that performs a specific task but does not return a value. Subroutines are invoked by using their name followed by parentheses. They are often used for executing a sequence of steps or actions without needing to return a result.

Remember, when using VBScript, understanding the distinction between functions and subroutines is essential for writing efficient and organized code.
