    Cool Read / Write To Text File

    I am trying to read a ".txt" file and append to the end of the file to create an on going list. I have found some examples from previous issues on this forum but I am have trouble with my output in the text file not exiting the loop. I am guessing that the problem is with the "Do Until sdr.AtEndOfStream" line. Can someone explain what I am doing wrong, and where could I reference something to fix the problem. Thank you in advance.

    Code:
    Public Sub WriteFile(strMapNumber, str200Map)
    
    Dim FileName As String
    FileName = "C:\Temp\Duplicate_OH.txt"
    
    If Dir(FileName) <> "" Then
       
        Const ForReading = 1, ForWriting = 2, ForAppending = 8
        Const TristateUseDefault = -2, TristateTrue = -1, TristateFalse = 0
    
        Dim fso As Object
        Dim fdw As Object, sdw As Object
        Dim fdr As Object, sdr As Object
        Dim strText As String
         
         'create file sysytem object
        Set fso = CreateObject("Scripting.FileSystemObject")
        
         'get file to read and open text stream
        Set fdr = fso.GetFile(FileName)
        Set sdr = fdr.OpenAsTextStream(ForReading, TristateUseDefault)
         
         'create new file to write to
        fso.CreateTextFile (FileName)
        Set fdw = fso.GetFile(FileName)
        Set sdw = fdw.OpenAsTextStream(ForAppending, TristateUseDefault)
         
        'iterate through the end of first file
    
        Do Until sdr.AtEndOfStream
            'read string from the first file
            strText = sdr.ReadLine & vbNewLine  '<--added carriage return to jump on the next line
            'write to the second one
            sdw.write strText & "100 Scale: " & strMapNumber & vbTab & "200 Scale: " & str200Map & vbNewLine
            
        Loop
          
        'close both files and clean up
        sdr.Close
        sdw.Close
        Set sdr = Nothing
        Set sdw = Nothing
        Set fdr = Nothing
        Set fdw = Nothing
        Set fso = Nothing
            
    Else
    
        Set fso = CreateObject("Scripting.FileSystemObject")
        Set fdw = fso.CreateTextFile("C:\Temp\Duplicate_OH.txt", True)
        
        fdw.writeline ("This Is A Test1.")
        fdw.Close
    
    End If
    
    End Sub
