Deleting header lines in text file

I am writing data to an appending text file.  However, each batch file that is written has a header line(these are all the same).  The first header line is fine, but I don't not want any more subsequent headers after that.  Here is the code I have now, but for some reason it is not deleting any of my header lines...  Any suggestions or other possible solutions?

Header= <COLUMNS>|OFFICE_ID|TERMINAL_ID|OFFICE_NAME|PHONE....>

Code:
Open "c:\officeOutput.txt" For Append As #2
       
 'delete extra header lines
 For i = 0 To UBound(lines)
    str = lines(i)
    If InStr(str, "COLUMNS") > 0 Then
        lines(i) = vbNullChar
    End If
Next

 'uses filter to delete lines
lines = Filter(lines, vbNullChar, False)

 'write data
For j = 1 To UBound(lines)
      Print #2, getField(j,1) + getField(j,2)+getField(j,3)....
Next

Close#2

Hi jennifere,
I'm not sure what you are trying to achieve here, nor where the data is coming from to be appended to the file.
From your code it seems that some procedure is creating an array of lines which you then wish to append to the output file. If I am reading correctly, you don't wish to append any header lines. (-where are they coming from ??)
In any case, I would simlify to the following:

Open "c:\officeOutput.txt" For Append As #2
For j = 1 To UBound(lines)
    If InStr(lines(j), "COLUMNS") = 0 Then
      Print #2, getField(j,1) + getField(j,2)+getField(j,3)....
    end if
Next
Close#2

Regards .. Alan

I made a function that does the job,

Function DeleteLineContaining(Filename As String, LineID As String)
    Dim BUFFER As New Collection
    Dim MYLINE As Variant
    Open Filename For Input As #1
        While Not EOF(1)
            Line Input #1, MYLINE
            BUFFER.Add MYLINE
        Wend
    Close #1
    Open Filename For Output As #1
        For Each MYLINE In BUFFER
            If InStr(1, MYLINE, LineID, vbTextCompare) = 0 Then
                Print #1, MYLINE
            End If
        Next
    Close #1
End Function

Private Sub Form_Load()
    Call DeleteLineContaining("c:\officeOutput.txt", "COLUMNS")
End Sub

Okay, never mind.  I figured out the problem on my own.  I was writing my data to a collection and then trying to delete lines.  Anyhow, with a little bit of code rearrangement, it is working now.  I will go ahead and split the points because you both responded so quickly.  I appreciate it!  =)
