Re: [Jprogramming] if (a v) were a valid expression...
Thank you Pepe, Another option that would seem more useful/general (a v v2 v3) captures u into the full argument u`v`v2`v3 a (a n) would if n not gerund, u`(n ar) a, and if n is a gerund u`n a (a n v2 v3 v4) would ar n if not gerund, and then produce u`n`v2`v3`v4 a This would allow for easy strand notation, with any termination character. a (norv) can return (a gerund) to continue parsing Any train combo/rearrangement can be done with f g h ==> f ((@.0 1 2) g h) (a1 v) a2 is usefully separated into a1 as the parsing guard/validator with initial parameters, and a2 as the final processing function. This allows for any of the original and option 2 alternatives with much more flexibility. I was asking for custom parser utilities, and not for J to change its parsing.

What should 7 { 2 3 5 do (if it were valid)?
But, also, should it be valid? If so, why?

I cannot find what (a v) did back then. Early J had a complete language of bidents/tridents. It was beautiful and powerful. Not five people understood it. It was removed in J5, never to return.

Re: [Jprogramming] value error using math/uu in v8.07 *Console*
in addon: math/uu all calls to "wd" have been removed. This should fix the value error when running under jconsole. Please update: math/uu. Version number is now: 2.1.26.
