this.pos = POSITION; 
this.delay = DELAY; 
this.i = 0;

function clearMessage(){ 
this.pos = POSITION; 
} 
var scroll = new bannerObject(); 
function scroller(){ 
scroll.out += " "; 
if(scroll.pos>0) 
for (scroll.i = 0; scroll.i < scroll.pos; scroll.i++){ 
scroll.out +=" " ; 
} 
if (scroll.pos>= 0) 
scroll.out += scroll.msg; 
else 
scroll.out = scroll.msg.substring(-scroll.pos,scroll.msg.length); 
document.noticeForm.notice.value = scroll.out; 
scroll.out = " "; 
scroll.pos--; 
scroll.pos--; 
if (scroll.pos < -(scroll.msg.length)) { 
scroll.reset(); 
} 
window.setTimeout("scroller()", scroll.delay); 
} 
</script> 
</head> 
<body onload="scroller()" bgcolor="#000000" link="#C0C0C0" vlink="#C0C0C0" alink="#008080" text="#C0C0C0">

len = msg.length; 
window.status = msg.substring(0, seq + 1); 
seq++; 
if (seq >= len) { 
seq = spacelen; 
window.setTimeout("Scroll2();", interval); 
} 
else 
window.setTimeout("Scroll();", interval); 
} 
function Scroll2() { 
var out = ""; 
for (i = 1; i <= spacelen / space10.length; i++) 
out +=space10; 
out = out + msg; 
len = out.length; 
window.status = out.substring(seq, len); 
seq++;
