Since SSE3 would fail on all CPU lines released before 2004 (and many released before 2005), this seems to mean that you are suggesting that J's arithmetic core be doubled -- with a side-by-side implementation of SSE3 support and non-SSE3 support? Perhaps more useful would be some documentation on how to construct and call user-defined machine language code from within J. (I'm thinking something different from cd here -- I'm thinking: let's generate a sequence of literals in J which are the machine code -- how do you call such a thing as a function from within J?) -- Raul
