In: http://www.jsoftware.com/jwiki/Doc/Articles/Play191 (Chapter 31, J be nimble, J be quick) the version of mt attributed to Mike Day fails with value error: nimsum
Can anyone see what nimsum is supposed to be? It only occurs once (outside a comment). I've tried equating it to the verb NS, the "nim sum" derived at the start of the article, but although mt then runs, it does not produce the same table as the previous definition of mt (quite apart from needing to be run as (mt 4) not (mt 5) like the previous one).
