    books   = excel.workbooks();
    book    = books.add();
    sheets  = book.worksheets();
    sheet   = sheets.itemFromNum(1);

    ExcelCOM   = sheet.comObject();

    txtBuffer = new TextBuffer();
    while select ct
    {
        linenum++;
        newLines++;

        txtBuffer.appendText( strfmt("%1\t%2\t%3\n", ct.AccountNum ,ct.Name, ct.Email));
        if( newLines == maxLines)
        {
            txtBuffer.toClipboard();
            txtBuffer.setText("");
            beginLines = linenum+titleLines+1- newlines;
            range = sheet.range(strfmt("A%1" , beginLines)).comObject();
            range.Select();
            ExcelCOM.paste();

            newLines=0;
        }
    }
    if( newLines!=0)
    {
        txtBuffer.toClipboard();
        txtBuffer.setText("");
        beginLines = linenum+titleLines+1- newlines;
        range = sheet.range(strfmt("A%1" , beginLines)).comObject();
        range.Select();
        ExcelCOM.paste();

    }
    book.saveAs("C:\\1abc.xls");
    excel.visible(true);
}

考虑到textBuffer能存储的文本长度有限，所以需要分批次将数据从textBuffer粘贴到Window粘贴板。
