tall_man,
Nice catch. I actually did see the fence post error but must not have posted the corrected copy. I will update the example in Pugs as well. WRT allowing code refs, I had to figure out where to draw a line. I suspect that my first challenge didn't go over so well because it was a fairly complicated problem. I was trying the KISS approach here to get more of a response, which seemed to work. OTOH, please provide a feature complete solution!
