Example 1

NOTE: Before you insert the JavaScript code, remove the following code:

   <SCRIPT>
   <!--
   </SCRIPT>
   //-->

Insert the following script into your normal HTML Web page:

   <SCRIPT LANGUAGE="JavaScript">
   <!--
   // Scrolling text string.
   var scrollString = "Replace this string with your text."

   // Width of the scrolling area.
   var width = 120;

   var stringLength = scrollString.length;
   var pos = 1 - width;
   // Start far enough to the left so that only one letter shows.

   function ScrollMessage(){
      var ScrollMessage = "";
   // Initialize the string to be printed.

       pos++;
   // Move to the right in the string.

       if (pos == stringLength)
   // Start over if the string is done.

       pos = 1 - width;
   // Scrolling

       if (pos<0) {
   // Add spaces to beginning if necessary.

           for (var i=1; i<=Math.abs(pos); i++)
               ScrollMessage = ScrollMessage + " ";
   ScrollMessage = ScrollMessage;
      + scrollString.substring(0, width;
      - i + 1);
    }
   else
   ScrollMessage = ScrollMessage;
      + scrollString.substring(pos, pos +;
   width);
   window.status = ScrollMessage;
   // Print the string.

       setTimeout("ScrollMessage()",100);
   // Repeat after 1/10 second.
   }

   //-->
   </SCRIPT>

In order for the message to function, modify the <BODY> tag so that it looks like this:

   <BODY OnLoad="ScrollMessage()">

Example 2

To add JavaScript to a FrontPage Web page, follow these steps:

Start FrontPage Editor.
On the Insert menu, click Script.
Under Language, click JavaScript.

In the Script box, type the following code.

NOTE: You can modify the values for strText and intSpeed to specify your own message and scrolling preferences.

      var strText="This is a scrolling message!";
      var intText=strText.length;
      var intSpeed=25;
      var intWidth=100;
      var intPos=1-intWidth;

      function scroll()
      {
        intPos++;
        var strScroll="";
        if (intPos==intText)
        {
          intPos=1-intWidth;
        }
        if (intPos<0)
        {
          for (var i=1; i<=Math.abs(intPos); i++)
          {
            strScroll=strScroll+" ";
          }
          strScroll=strScroll+strText.substring(0, intWidth-i+1);
        }
        else
        {
        strScroll=strScroll+strText.substring(intPos,intWidth+intPos);
        }
        window.status = strScroll;
        setTimeout("scroll()", intSpeed);
      }
