when I define these in j8 repl, it works as I'd want conj_cat_=: 2 :'v@:u^:a'
>: conj_cat_ ] 1 9 >: ^:8 ] 1 9 this is also the 'right' answer: >: conj_cat_ ] a 15 >: ^:8 ] 7 15 a_cat_=: 2 >: conj_cat_ ] a 9 The issue is entirely related to accessing variables at time of definition. > I think you have said that the value of 'a' should be 8 because itmakes no > sense for it to be 5. But, it's actually 9. The a accessed in verb_dog_ should indeed be 9. For definitions entered in J7 files within a cocurrent context, the locale for a conjunction is wrong... it is the callers. It is correct for a verb. ----- Original Message ----- From: Raul Miller <[email protected]> To: Programming forum <[email protected]> Cc: Sent: Saturday, November 16, 2013 8:52:16 PM Subject: Re: [Jprogramming] bug in conjunction locales? What do you mean by "execute"? Consider this example: a_cat_=: 8 a_dog_=: 9 a=: 7 conj_cat_=: 2 :'u&.(v inv)' verb_dog_=: do bind 'a' thingy=: verb_dog_ conj_cat_ % thingy 5 I think you have said that the value of 'a' should be 8 because it makes no sense for it to be 5. But, it's actually 9. Conceptually speaking, conjunctions are executed multiple times - they have both "parse time" and "execution time" semantics. And, given your logic, I think you are talking about their "parse time behavior", not their "execution time behavior". Does this distinction sound meaningful to you?
