Ah, this is a much more direct example than my 'conj'~ . Thanks, I'll use it in the future. > I still do not see how a conjunction could be constructed tacitly. It may not be possible. But J has some back doors that Roger forgets to lock sometimes.

Yes, this is the heart of adverbial programming. Once you have some utility adverbs to coerce arguments into the proper format (like my pet (`'') ), the rest is normal tacit verb programming. Of course, I always feel a pang of guilt at this approach and attempt to do as much processing "adverbally" as possible, but I end up resorting to gerund-processing tacit verbs at some point. > a la Oleg's strand notation implementation, [which] > relied on a global noun to accumulate the elements but, > I think, this might be avoided by embedding the > accumulation in the resulting adverb at each step Do you have a pointer to Oleg's implementation? All I'm aware of is my own, described/announced at [1] and implemented at [2], as an (explicit) conjunction that accumulated state in its right-hand argument, n . This avoided the need for globals et al (it also has some fancy, if unneccesary, embellishments). But I expect Oleg's implementation predated mine, unless you're referring to [3], which was a followup to my post. -Dan [1] http://www.jsoftware.com/pipermail/programming/2009-July/015565.html [2] http://www.jsoftware.com/svn/DanBron/trunk/environment/strand.ijs [3] http://www.jsoftware.com/pipermail/programming/2009-October/016648.html ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
