I doubt if anyone would want a slow, unstable, and incomplete (hence buggy) program only because it is short. > The vertices of an "arbitrary polygon" does not have integer coordinates. Arbitrariness is related to the polygon's form, not to the domain of its coordinates. It is perfectly possible to speak of arbitrary polygons (or whatever figures) in a discrete coordinate system, e.g. raster. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
