Hi Bob, Many thanks for your feedback. Raul confirmed that, alas, there is no related J code.
P.S. I hope newbies enjoy your videos as much as I do; ironically for someone that likes to read and write tacit code, I really learn by looking at examples (and I would be totally lost without an interpreter). ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
