After I'm through building my string with a string builder, I have check to see what is contained in the string in debug mode. Everything is there. However, when I write the string to a text file, it is chopped off. Any idea why?

Dim fs As New FileStream("W:\WORKING\A&T_TECH\WebTest Data\Initial_Extracts\" & strDB & "_" & strSS & "_syntax.sps", FileMode.Create)
        Dim sw As New StreamWriter(fs)
        Dim i As Integer
        Dim j As Integer
        Dim strSyntax As New System.Text.StringBuilder(25000)
        Dim nl = Environment.NewLine

        intPrevId = dt.Rows(0)("cde_question")
        strSyntax.Append("RECODE Q" & dt.Rows(0)("cde_question") & " ")
        For i = 0 To dt.Rows.Count - 1
            intCurId = dt.Rows(i)("cde_question")
            If intCurId = intPrevId Then
                j = j + 1
                strSyntax.Append("(" & dt.Rows(i)("cde_Choice") & "=" & j & ") ")
                intPrevId = dt.Rows(i)("cde_question")
            Else
                strSyntax.Append("." & nl)
                strSyntax.Append("RECODE Q" & dt.Rows(i)("cde_question") & " ")
                j = 0
                strSyntax.Append("(" & dt.Rows(i)("cde_Choice") & "=" & j & ") ")
                intPrevId = dt.Rows(i)("cde_question")
            End If
        Next

        strSyntax.Append("." & nl & nl)
        sw.Write(strSyntax)

From the code you posted I do not see a sw.Close(). If the file is not closed correctly that will cause the type of problem you are seeing. Are you closing the file?

It's funny, I do have a sw.close(), but I was breaking on there an then checking the file. After I ran that, everything was fine. Thanks.
