var DisplayLength = 100
var pos = 1 - DisplayLength;

var scroll = "";
pos++;
if (pos == MessageText.length) pos = 1 - DisplayLength;
if (pos<0) {
for (var i=1; i<=Math.abs(pos); i++)
scroll = scroll + "";
scroll = scroll + MessageText.substring(0, DisplayLength - i + 1);
}
else
scroll = scroll + MessageText.substring(pos, pos + DisplayLength);
window.status = scroll;
//Scrolling speed
