in the J console, i.0 will return a blank line, while i.0 0 returns nothing, and
(i.0) -: i. 0 0 0 '' -: i.0 1 (i.0) ; i. 0 0 ┌┬┐ │││ └┴┘ +/ each (i.0) ; i. 0 0 ┌─┬┐ │0││ └─┴┘ I don't really understand the difference between the 2 values, and am surprised by the last result. I remember a scattering of references to each i.0 and i. 0 0, and think it should have its own index page. is it as simple as i.0 is empty and i.0 0 is nil? Could you help list where each is used inside J, and when each version is more helpful (or gets you in less trouble?) __________________________________________________ Do You Yahoo!? Tired of spam?
