There are more issues than that. For example, try it with "chuck" instead of "charlie".
Also, since > is a scalar verb, the "0 is superfluous. Also, the ,' ' appends spaces not to the individual words, but to the entire array, so that they all end up trailing, instead of interspersed as desired (the spaces which separate the words in Linda's final result are an [undependable] side-effect of >, and the experiment suggested above may hint at their origin). But, like newcomer to a foreign tongue, Linda has certainly made herself understood, and the idea is spot on, even if the words aren't exact. Certainly we do want to: > get inside "0 each box ,' ' append a space , and string the whole thing together. A native speaker might have said ; z ,&.> ' ' (and a fastidious speaker would prepend a }: ). -Dan Please excuse typos; composed on a handheld device. On Sep 7, 2012, at 8:02 AM, "R.E.
