[help]platform game,character stops earlier before collision to right wall

[ash_at_risk]

hi guys,
I m under the process to create a platform based game,but stuck in a problem ,its probably concern with x-axis, actually my player stops certain distance before right wall and with left wall too,i tried to reduce the distance but end up in failure,i have attached the concern fla.

function moveman(Char:Object, timediff:int)
        {
            if(timediff<1)
            return;
            var vertical:Number=Char.dy + gravity*timediff;  
            if (vertical>15.0)
            vertical=15.0;
                Char.dy+= timediff*gravity;
                var horizontalDist:Number=0;
                var newDirection:int=Char.direction;
                var newAnimstate:String="stand";
                if (Char.moveLeft)
                {
                    horizontalDist=-Char.walkspeed * timediff;
                    newAnimstate="walk";
                    newDirection=-1;
                }
                else if(Char.moveRight)
                {
