例子

新增一個模組，並新增以下程式碼 -

Private Sub Constant_demo_Click()
   Dim NumArray(3)
   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.
   msgbox("The value at Zeroth index of NumArray is " & NumArray(0))
   msgbox("The value at First index of NumArray is " & NumArray(1))
   msgbox("The value at Second index of NumArray is " & NumArray(2))
   msgbox("The value at Third index of NumArray is " & NumArray(3))
End Sub

當執行上面的函式時，它會產生下面的輸出。

The value at Zeroth index of NumArray is 
The value at First index of NumArray is 
The value at Second index of NumArray is 
The value at Third index of NumArray is
