Skip says: I don't think it is a good idea to give the monadic and dyadic forms of primitives separate pages in the reference tutorial. When a novice sees a symbol in an expression, they will want to go to the page for that symbol. If there are two pages for that symbol, which page do you take the novice to, when they click on the symbol on the opening page? Making the assumption that the novice knows all about monadic and dyadic when they first visit the reference tutorial is a bad assumption. Even intermediate-level J-ers aren't always able to guess the valence of a specific symbol in an expression without taking some time to analyze it. The revelation that a function can have single and dual-arguments, which can do very different things, is something that should be woven into each primitive function description. One of the key parts of the template for every primitive will be the part that makes sure that the novice understands the meaning of monadic and dyadic (and other key concepts) before proceeding, no matter what primitive they stumble upon first. That is the purpose of the exclamation-point and question-mark graphics I proposed previously. Again, this reference tutorial should be focused on the novice, not the intermediate or expert-level J programmers, if we want to use it to broaden the usage of J. The only alternative that I can think of to the "!?" hyperlinked graphics in each primitive template would be to have a "beginners go here first" link on the J Softwate home page that links to a page explaining that symbols can have one or two characters, monadic and dyadic usage, and perhaps a couple of other concepts that are crirical for the beginner to understand. Even then, other concepts such as rank, and parts of speech would possibly be better revealed at points in the primitives' description text when the necessity arises. Bringing new concepts into a tutorial when they are needed is a tried and true educational method, as opposed to trying to explain all the new concepts before wading into some actual code. .Skip Cave ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
