Yes, and perhaps I should be more explicit about what I'm trying to say there. The expression 1 :'+/ % #' is tacit in two senses: (a) the : expression takes a constant argument rather than a named argument. (b) The result of the : expression does not contain any named arguments. In contrast, A=: '+/ % #' 1 : A only satisfies definition (b). Meanwhile, the definition 1 :'(+/ % #)y' only satisfies definition (a). And, of course: B=: '(+/ % #)y' 1 : B satisfies neither definition. > "Do you have an example where adverbial (or conjunctional) performance > might be critical?" If you put adverb definition inside a verb and then use that verb with high low rank on a large array, the adverb performance might become significant. But I imagine you would need a somewhat complicated scenario before anything like this could arise. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
