Well, Empty is a special value in VBA. And I forgot to mention, there are two kinds of "empty" arrays that are not Empty. So it's six times as good as a normal language.

Here's an example:

    ' x can be anything, including an array, but
    ' defaults to the value Empty.
    Dim x

    ' y is an array of values that can be anything,
    ' which defaults to an empty array.
    Dim y()
    
    ' Initialize x as an empty array
    x = Array()
    
    ' The following two statements print 0 and -1.
    Debug.Print LBound(x)
    Debug.Print UBound(x)
    
    ' The following two statements error with
    ' "Subscript out of range" even though y
    ' is also a kind of empty array.
    Debug.Print LBound(y)
    Debug.Print UBound(y)

IIRC in Visual Basic these are arrays with lower bound bigger than upper bound.

Sounds like a trick question. How about the array of the largest number?
