So, for example, (viewmat ?~ 13) -: viewmat #:i.67 1 Note that both the arrays ?~13 and #:i.67 and their respective viewmat visualizations are completely different animals. The -: is telling you nothing (except that viewmat is defined to always return i.0 0). -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
