Hi Tarl,

Incidentally when this discussion came up before, I remember there was 
some discussion on how this was handled in Sun's implementation, but I 
can't remember what the outcome was.

What is the result of typing "2 0 /" into the OpenBoot Forth 
interpreter? Does it call invoke a low level trap handler, throw a Forth 
exception, or is the zero denominator detected in some other fashion?


ATB,

Mark.
