title: Excel formula to change the value of another cell?
body: <p>is it possible to force an [UDF] user-defined-function to return result on a cell we specify ?
  in another words : if I execute an UDF in the cell <strong>A1</strong>  it will return result in <strong>A2</strong> cell , but what if I want to change <strong>A2</strong> by another cell ? </p>
