bendy line help!

[dendk]

I am trying in vain to create a few lines of simple AS that will allow me to bend a line (with the ends remaining fixed) with the movement of the mouse.
Will anyone (who has more AS skill than me (which is pretty much everyone) throw me a bone?!)

var pointA = {x:50, y:200};
var pointC = {x:500, y:200};
onMouseMove = function(){
clear();
lineStyle (1, 0xFF0000);
moveTo(pointA.x, PointA.y);
curveTo(_xmouse, _ymouse, pointC.x, pointC.y);
updateAfterEvent();
