If the verb train has an even number of verbs in it, then it is called a hook.
(f g) y <=> y f g y NB. monadic hook x (f g) y <=> x f g y NB. dyadic hook See http://www.jsoftware.com/help/dictionary/dictf.htm Also, a hook can always (I believe) be turned into a fork by adding the [ verb to the left of the train (has to be [ and not ] because of the dyadic case): ([ f g) y <=> (f g) y The situation is similar for the dyadic case. ___________________________ David Vaughan On 19 Aug 2012, at 18:21, Owen Marschall <[email protected]> wrote: > Hey all, J beginner here.
