我没有在这里提供WIN32 GUI可执行文件，而是提供了一个准备编译到COM Dll的程序（用例是某人在进行COM开发）。这是源代码。人们可以将其合并到自己选择的GUI中。

这里有一个示例HTML脚本，它将ROT内容写入网页。这只适用于Internet Explorer

    <!DOCTYPE html>
    <html>
    <head>
        <title>Rot Viewer Test</title>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
        <style>
            table {
                border: 1px solid black;
            }
            th, td {
                padding: 5px;
                text-align: left;
                font-family: Arial; font-size: 10pt;
            }
            th {
                background-color: darkblue;
                color: white;
            }
            tr:nth-child(even) {background-color: #f2f2f2}
        </style>
    </head>
    <body>
        Only works with Internet Explorer because of the use of ActiveXObject!
        <table  id="simpleRot" >
