Bob, Yes, I like the most recent animations. Here is some of my thought process.
Why have the + signs in the last two examples when the arrows suggest the transition? Why have array and vector examples when the verb is scalar, anyhow? Why not reduce all of the examples to scalars except maybe to economize on time? The nonscalar activity is better covered in a generic section on how verbs deal with higher or lower rank data, except where a verb does this in a special manner as does the dyad Append and its relatives. Shouldn't the animation focus on what the target does (e.g., 1r2 + _6 in the case of Plus) and what it does not do (e.g., 2 + 'a' in the case of Plus)? Great work, everybody, especially, Bob. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
