The point is not about what is plausible. It is about the very fact that we have to deal with plausibility instead of simply being certain. > J verbs execute right to left? We know this for an expression with explicitly listed many verbs and arguments. But u/y (for 2<#y) is not the same thing. If -/3 5 9 2 is to be understood the same way as 3-5-9-2, then I believe this should be said explicitly. >> ... to the effect that, e.g., +/'z' -- a meaningless expression -- >> has a definite value, 'z', and consequently so do +/\'z' and +/\.'z'. > > It's not meaningless, it's an identity.

Does +/'z' not read as `summing up a string' -- which is what I mean by `meaningless'? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
