      Impossible. Client-side JavaScript in an HTML document in the default
      security environment has no ability to read or write files on the local
      hard disk.

      JavaScript can store information in a cookie, but the underlying
      implementation is under the control of the browser. In other words,
      sure, IE stores cookies as files, so you can argue that "JavaScript lets
      you read and write files", but it is hardly the level of control that
      one expects when you say "you can read and write files".

      Anyway, if that is an exercise, you need a better instructor, one who
      understands that client-side JavaScript in an HTML document in the
      default security environment has no ability to read or write files on
      the local hard disk.

          Will this do?

          <html>
          <head>
          <title>readwrit .htm</title>
          <script type="text/javascript">
          function readwrit(parm) {
          var sFIL = "C:\\Temp\\read writ.txt";
          var oFSO = new ActiveXObject(" Scripting.FileS ystemObject");
          var oOTF;
          if (parm == 1) {
          oOTF = oFSO.OpenTextFi le(sFIL,1);
          document.form1. data.value = oOTF.ReadAll();
          } else if (parm == 2) {
          // "Permission denied" error on secord try!
          oOTF = oFSO.OpenTextFi le(sFIL,2,true) ;
          oOTF.Write(docu ment.form1.data .value)
          }
          }
          </script>
          </head>
          <body>
          <form name="form1">
          <textarea name="data" cols="60" rows="10"></textarea>
          <br>
          <input type="button" value="Read" onclick="readwr it(1)">
          &nbsp;
          <input type="button" value="Write" onclick="readwr it(2)">
          &nbsp;
          <input type="reset" value="Clear">
          </form>
          </body>
          </html>
