Sample Visual Basic Procedure

   Sub ChangeExcelSource()

   Dim i As Integer
   Dim k As Integer

   ' Create a variable to store the worksheet reference string.
   Dim linkname As String

   ' Create a variable to store the position of the worksheet
   ' reference in the .SourceFullName property of the OLEFormat
   ' object.

   ' Set a For loop to go from slide 1 to the last slide in the
   ' presentation.

                 ' type to Automatic. First find where the worksheet
                 ' reference is, and then store it in linkname. Next
                 ' assign the new path and concatenate the chart name
                 ' to the end of the path.
                 With .LinkFormat
