使用者定義函數中的範圍引數被視為 Variant 處理時，則只能夠和超高速相容。例如，對於以下列方式呼叫工作表的函數 =MyFunc(A1:E4, 5, 4)：

      Function MyFunc (MyData As Variant, Rows As Long, Cols As Long) As Double 
	For I = 1 to Rows 
		For J = 1 to Cols
			MsgBox MyData(I, J) 'or otherwise work with the cell range as an array
		Next J 
	Next I
End Function
