Empty is a special value that can only be held in a Variant variable. In Visual Basic, variables declared as any of the specific data types cannot hold the value of Empty-only variables declared as Variant. In VBScript, of course, all variables are Variant variables. A Variant variable is "empty", and has the Empty subtype, after it has been declared, but before any value has been placed within it. In other words, Empty is the equivalent of "not initialized". Once any type of value has been placed into the variable, it will take on one of the other subtype, depending on what the value is. Let us take a look at some examples:
