Hi Skip, I like using @: instead of [: and throwing a hook in shortens things a little bit by getting rid of one ] and 5&| gets rid of another.
+/@:(#~ 0 = 5&|)@(100+i.900)"_ or if you were willing to use 900 as the argument to the tacit verb +/@:(#~ 0 = 5&|)@(100 + i.) 900 which in addition to being shorter strikes me as a little more elegant Cheers, bob > On Jan 16, 2018, at 8:39 PM, Skip Cave <[email protected]> wrote: > > [: ([: +/ ] #~ 0 = 5 | ]) (100+i.900)"_ ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
