There's a little script that's been floating around lately that lets you
scroll text in a form's text field or the window's status bar.  This is
a modified version:

<SCRIPT LANGUAGE="JavaScript">
<!-- 
function scrollmsg(seed)
{
        var m1  = "HTML       Forms         Imagemaps         CGI        ";
        var m2  = "Perl        Advanced Applications        ";
        var m3  = "Servers       WWW Newsgroups        Local Info       ";
// Change the above to the message you want to see scrolled.

        var msg=m1+m2+m3;
        var out = "";
        var c   = 0;

        if (seed > 100) {
                  seed--;
                  var cmd="scrollmsg(" + seed + ")";
                  timerTwo=window.setTimeout(cmd,110);
// Increase the number to make it slower, decrease ^ it to make it faster.

        }
        else if (seed <= 100 && seed > 0) {
                for (c=0 ; c < seed ; c++) {
                        out+=" ";
                }
                out+=msg;
                seed--;
                var cmd="scrollmsg(" + seed + ")";
                    document.display.box.value=out;
//   Change "display" to the name of your form, and "box" to the name of
//      the text box in the form. Or if you want to scroll on the status bar
//      use:
//              self.status=out;

                timerTwo=window.setTimeout(cmd,110);
//  Increase to make slower, decrease to make faster...or use

        }
        else if (seed <= 0) {
                if (-seed < msg.length) {
                        out+=msg.substring(-seed,msg.length);
                        seed--;
                        var cmd="scrollmsg(" + seed + ")";

                        document.display.box.value=out;
//  Change "display" and "box"  or use:
//                      self.status=out;

                        timerTwo=window.setTimeout(cmd,110);
//  Increase to make slower...

                }
                else {
                        document.display.box.value=" ";
//  Change the above line or use:
//                      self.status=" ";

                        timerTwo=window.setTimeout("scrollmsg(15)",110);
//  Change "15" to width of text field or width of status bar (100)

                }
        }
}

// -- End of JavaScript code -------------- -->
</SCRIPT>

** Put this in your BODY tag:
  onLoad="timerONE=window.setTimeout('scrollmsg(15)',500)"
(change 15 to the width of the text field in your form, or make it
100 if you want to scroll a message across the bottom status bar)

** Here's a the sample form used with this script.
<form name="display">
<input type="text" name="box" value="" size="15"><br>
</form>

I didn't originally write the script, don't credit me.  I forget who did,
but they gave permission for its use.
