function trimAllSpaces (str:String) : String
	{
		var tmpStr:String = trimOnlySpace(str);
		tmpStr = remove (tmpStr, "\n");
		tmpStr = remove (tmpStr, "\t");
		tmpStr = remove (tmpStr, "\r");

function trimPunc( str:String ):String {
	
		var marks:Array 	= ["!",",",".",";",":","\"","(",")","?"];
		var nS:String = str;
		
		var iLength:Number = marks.length;
		for (var i:Number = 0; i< iLength; i ++ ) {
			nS = replace (nS, marks[i], "");
		}
		return nS;
