Sample Visual Basic Procedure

   Sub DirLoop()

      Dim MyFile As String, Sep As String

      ' Sets up the variable "MyFile" to be each file in the directory
      ' This example looks for all the files that have an .xls extension.
      ' This can be changed to whatever extension is needed. Also, this
      ' macro searches the current directory. This can be changed to any
      ' directory.

      ' Test for Windows or Macintosh platform. Make the directory request.
      Sep = Application.PathSeparator

      If Sep = "\" Then
         ' Windows platform search syntax.
         MyFile = Dir(CurDir() & Sep & "*.xls")

      Else

         ' Macintosh platform search syntax.
         MyFile = Dir("", MacID("XLS5"))
      End If

      ' Starts the loop, which will continue until there are no more files
      ' found.

      Do While MyFile <> ""

         ' Displays a message box with the name of the file. This can be
         ' changed to any procedure that would be needed to run on every
         ' file in the directory such as opening each file.

         MsgBox CurDir() & Sep & MyFile
         MyFile = Dir()
      Loop

   End Sub
