apply does not work with dyadic verbs, and cannot produce modifiers. Consider the following simple looking eval function.
eval =: 1 : ' a: 1 : m' 2 '+' eval 1 2 3 3 4 5 + '/' eval 1 2 3 6 '+/' eval(+:@) 1 2 3 12 +:@+'/' eval 1 2 3 22 +: +'/' eval 1 2 3 12 (+: '@' eval +)'/' eval 1 2 3 22 +: '@' eval +'/' eval 1 2 3 12 The last statement is interesting because it seems to alter the normal conjunction train processing (sometimes in desirable ways) instead of just grabbing a single token as v. < '@' eval +'/' eval 1 2 3 NB. would be domain error without '@'eval ┌─┐ │6│ └─┘ eval is the key to how my multiline tacit code works: http://www.jsoftware.com/jwiki/PascalJasmin/Multiline%20tacit%20expressions%20with%20macros ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
