To me, the point isn't the "pattern" evoked by the &. conjunction, it's the whole concept of verb expressions and the expansion of possibilities, which APL only skimmed with f/ and f.g
I'm not sure why I should see this as a different point, but I think I understand what you've said.
The thing that does tug at me, it is getting my head around how a dyadic verb has an inverse. I think the same thing happens with #^:_1but I haven't yet seen nor thought up a good explanation for how those inverse cases were derived.
For the examples I'm familiar with, these are right inverses (the left argument is retained for the inverse case). -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
