' This VBScript function tests to see if a value passed is an even value.
' It returns the result of the value test in the name of the function itself = “IsEven”
' Initializes the value of “IsEven” to Boolean FALSE (Zero)
' This is intended to simplify the IF / END IF Block
' The MOD operator simply says Divide ValueIN by the value to the right of MOD (2) and capture the remainder.
' If the remainder is Zero we can assume an even number - True.

Function IsEven( ValueIN)
	IsEven = FALSE
	If (ValueIN Mod 2) = 0 Then
		IsEven = TRUE

' Main program to call “IsEven” It’s only job is to do three things in one statement:
' 1. Put up a message box, after

' 3. Capturing the result of the call to the “IsEven” function
