What is the difference between a Function and a Subroutine in VBScript?
In VBScript, a Function and a Subroutine serve different purposes and have distinct characteristics:
Function
A Function is used to perform a specific task and return a value to the calling code. It can accept input parameters, process them, and then return a value back to where it was called.
Subroutine
A Subroutine, also known as a Sub, is a block of code that performs a specific task, but it does not return a value to the calling code. It can accept input parameters and process them internally, but it does not have a return value.
Overall, the key difference between a Function and a Subroutine in VBScript is that a Function returns a value to the calling code, while a Subroutine does not.
