Moving Backward through text

Hi all, I have a prog that hashes a text file and is able to skip though large portions of it in the forward direction.

I need to be able to do the same thing in the reverse direction. This is the forward one -

VB Code:

Dim wc As String, I%, z%
    ' *****************************
    Form1.MousePointer = 11
    If last_rcd = 1 Then
        CleanFields (1)
        rcdcnt1% = totrcds%
        'Form8.ProgressBar1.Value = 100
        Form1.NEXTBUT.Visible = False
        Form1.OptBut.Visible = False
        CLOSEFILE_CLICK
    End If
    ' *****************************
    Do
        If last_rcd = 0 Then 'filenum > 0 Then
            ShowRecord '(last_rcd)
            wc = Nsnap.SF1
            I% = CkKeyWC(wc)
            If ((I% = 0) And (Form4.Check1.Value = 1)) Or ((NoSupport$ = "yes") And (Form4.Check3.Value = 0)) Then
                nextjcn% = JCNcnt1% + 1
                SkipIt$ = "Y"
            ' **************
            ElseIf nextjcn% > JCNcnt1% Then
                SkipIt$ = "Y" ' Auto skip forward
            ElseIf nextjcn% < JCNcnt1% Then
                Close (Filenum)
                CleanFields (1)
                JCNcnt1% = 0
                rcdcnt1% = 0
                skipcnt2% = 0
                'Form8.ProgressBar1.Value = 0
                Form8.Label8.Caption = " "
                'Form8.Label17.Caption = "0%"
                Open Filename For Input As Filenum
                ReadCard (0)  ' Lable card
                ReadCard (1)  ' Read 1st card
                jcn = Left(textdata, 13)
                'form1.Refresh
                OLDJCN = jcn
                SkipIt$ = "Y" '
            Else
                SkipIt$ = "N" '
                nextjcn% = JCNcnt1% + 1
            End If
            'z% = (rcdcnt1% / totrcds%) * 100
            'Form8.ProgressBar1.Value = z%
        End If
    Loop Until SkipIt$ = "N" Or last_rcd = 1 'filenum = 0
    ' ************************
    NoSupport$ = "no"
    flagopt% = 0
    Get_Show ' Move fields to display window
    Form1.MousePointer = 0

I thought I could just modify it and this is what I get that kinda works -

VB Code:

Dim wc As String, I%, z%
    ' *****************************
    Form1.MousePointer = 11
    If last_rcd = 1 Then
        CleanFields (1)
        rcdcnt1% = totrcds%
        Form1.NEXTBUT.Visible = False
        Form1.OptBut.Visible = False
        CLOSEFILE_CLICK
    End If
    ' *****************************
    Do
    
        If last_rcd = 0 Then 'filenum > 0 Then
            ShowRecordReverse '(last_rcd)
            wc = Nsnap.SF1
            I% = CkKeyWC(wc)
            If ((I% = 0)) And (Form4.Check1.Value = 1) Or ((NoSupport$ = "yes") And (Form4.Check3.Value = 0)) Then '
                rcdcnt1% = rcdcnt1% - 1
                SkipIt$ = "Y"
            If ((I% <> 0)) And (Form4.Check1.Value <> 1) Or ((NoSupport$ = "NO") And (Form4.Check3.Value = 0)) Then '
                Close (Filenum)
                CleanFields (1)
                Open Filename For Input As Filenum
                ReadCard (0)  ' Lable card
                ReadCard (1)  ' Read 1st card
                ShowRecordReverse
            End If
            End If
        End If
    Loop Until SkipIt$ = "N" Or last_rcd = 1 'filenum = 0
    ' ************************
    NoSupport$ = "no"
    flagopt% = 0
    Get_Show ' Move fields to display window
    Form1.MousePointer = 0

It will read the record number in reverse, but not the text associated with the record.

Any Ideas?
