Thanks it works, but well.Now that I see that you are really monks in perl I will show my real problem. It is the following(besides that Im not good programming!!): I have a set of data like this: -90 120 -50 40 120 -180 -50 90 -90 45 ..., which are the (X,Y)coordinates of points in a 2d matrix. The thing is that I would like to sort this data in such a way that the order shows how close these points are from each other. The real objective behind it to make a contour plot from this points. So I have already the shape(points) in the 2d plot but now I want to connect them and have the contour. In fact I realised that regular programs draw lines between points in order of appeareance. So I got to the point of having to order them appropiately( or according to me by proximity). What do you suggest monks? -Arnold
