文字列を検索しcsvに出力するWordのVBA

FS社のAccessを［解析］→ RTF にエクスポートし、指定の文字列のある段落番号と位置を csv に出力するするための関数。本来は ページ−行−桁 を知りたかったのであるが、その方法が解らない．．．

'概要：第2引数で検索してCSVに書き出す。
Public Function SearchString(argFullName As String, argString As String, argFirst As Boolean) As Long
Dim mbTitle As String
Dim textFileName As String
Dim 段落 As Paragraph
Dim dsn As Long, i As Long
Dim ctrTotal As Long, nowAddr As Long, ctrPara As Long
Dim TextFile As String, TextArea As String
Dim NowFileName As String, NowPageCtr As Long, NowAjustCtr As Long

    mbTitle = MYObjName & "/SearchString"
    TextFile = Left(argFullName, InStrRev(argFullName, ".", -1)) & "csv"
    ctrTotal = 0
    dsn = FreeFile
        '初回時のみﾍｯﾀﾞｰを書き出し、2回目以降はｱﾍﾟﾝﾄﾞで開く。
    If argFirst Then
        Open TextFile For Output As #dsn
        GoSub SearchString_HeaderWrite
    Else
        Open TextFile For Append As #dsn
    End If
    NowFileName = ActiveDocument.FullName
    LNGAns = ActiveDocument.Paragraphs.Count    '総段落数 ‥‥たぶん
    ctrPara = 0
    For Each 段落 In ActiveDocument.Paragraphs
        ctrPara = ctrPara + 1
        nowAddr = InStr(1, 段落.Range.Text, argString, vbTextCompare)
        Do While nowAddr > 0
            ctrTotal = ctrTotal + 1
            NowPageCtr = 段落.Range.Information(wdActiveEndPageNumber)
            Write #dsn, argString, argFullName, ctrTotal, ctrPara, NowPageCtr, nowAddr
            nowAddr = InStr(nowAddr + 1, 段落.Range.Text, argString, vbTextCompare)
        Loop
    Next 段落
    Close #dsn
    SearchString = ctrTotal
    
Exit_SearchString:
    Exit Function
    
SearchString_HeaderWrite:
    Write #dsn, "検索文字", "ファイル名", "検索順", "段落番号", "ページ番号", "検索位置"
    Return

End Function

当面の目的は達したが、何とか改修したいので、コードを載せた。
