I would think the CADR compiler and the explorer compiler are pretty similar (I'd like to think they had common ancestry but I don't know how much LMI did before TI got to it)

It occurred to me to try the same on the Explorer. Now I have a half an answer.

The weird thing is I can (uncompile 'divp) and it starts working again. I thought I saw something in the doc about providing optimization parameters to the compiler, but I can't find it now.


ok
bear.
