You can draw a circle of the same radius around each point. These circles have one or two points of intersection. (1 if the points are on a diameter, else 2). Then you have to decide which of the two points is the true center, because your problem is not well constrained -- you need one more point on the circle to be sure. /\/\/\/*=Martin -- http://www.piclist.com#nomail Going offline?
