         NumArray(0) = "VBScript"
         NumArray(1) = 1.05
         NumArray(2) = 25
         NumArray(3) = #23/04/2013#

         Dim DynamicArray()
         ReDim DynamicArray(9)   ' Allocate storage space.

         Erase NumArray          ' Each element is reinitialized.
         Erase DynamicArray      ' Free memory used by array.

         ' All values would be erased.
         Document.write("The value at Zeroth index of NumArray is " & NumArray(0) & "<br />")
         Document.write("The value at First index of NumArray is " & NumArray(1) & "<br />")
         Document.write("The value at Second index of NumArray is " & NumArray(2) & "<br />")
