Dear J Forum: Let func be a dyadic function defined for atoms x and y. If Y is a boxed vector of atoms, 'x func each Y' will do the function between x and each atom of Y (i.e., one with many). And if X is a boxed vector of as many atoms, 'X func Y' will do the function between corresponding atoms of X and Y (i.e., many with many). But how can I do the many-to-one case, 'X func y'? The adverb "each" doesn't like the left argument. Sincerely, Leigh
