To set up the example, use a text editor such as Notepad to create the following text files.

The Dest.txt file should contain the following information:

   Last Name, First Name, Address, City, State, Zip Code
   John,Smith,1 Main St.,Seattle,WA,12345
   Jane,Doe,2 East Rd,Charlotte,NC,52631
   Tom,Jones,3 West Cir.,Tuscon,AZ,36258

The Source.txt file should contain the following information:

   Bill,Adams,6 Elm Ln.,Seattle,WA,85692
   Sue,Thompson,33 Maple Ct.,Las Colinas,TX,58692
   Jerry,Brown,32 Main Rd.,Tuscon,AZ,96524
   Pamela,Smith,88 Rain Rd.,Charlotte,NC,89526

Use file input and output (file I/O) commands in a Visual Basic macro.

The following macro demonstrates how you can use the Open, Line Input, and Print statements to read data from one text file and append it to another.

   Sub AppendFiles1()

      Dim SourceNum As Integer
      Dim DestNum As Integer
      Dim Temp As String

      ' If an error occurs, close the files and end the macro.
      On Error GoTo ErrHandler

      ' Open the destination text file.
      DestNum = FreeFile()
      Open "DEST.TXT" For Append As DestNum

      ' Open the source text file.
      SourceNum = FreeFile()
      Open "SOURCE.TXT" For Input As SourceNum

      ' Include the following line if the first line of the source
      ' file is a header row that you do now want to append to the
      ' destination file:
      ' Line Input #SourceNum, Temp

      ' Read each line of the source file and append it to the
      ' destination file.
      Do While Not EOF(SourceNum)
         Line Input #SourceNum, Temp
         Print #DestNum, Temp
      Loop

   CloseFiles:

      ' Close the destination file and the source file.
      Close #DestNum
      Close #SourceNum
      Exit Sub

   ErrHandler:

      MsgBox "Error # " & Err & ": " & Error(Err)
      Resume CloseFiles

   End Sub

After you run the macro, Dest.txt should resemble the following:

   Last Name, First Name, Address, City, State, Zip Code
   John,Smith,1 Main St.,Seattle,WA,12345
   Jane,Doe,2 East Rd,Charlotte,NC,52631
   Tom,Jones,3 West Cir.,Tuscon,AZ,36258
   Bill,Adams,6 Elm Ln.,Seattle,WA,85692
   Sue,Thompson,33 Maple Ct.,Las Colinas,TX,58692
   Jerry,Brown,32 Main Rd.,Tuscon,AZ,96524
   Pamela,Smith,88 Rain Rd.,Charlotte,NC,89526
