(...) No there is not. That being said, it's pretty easy to write one...if you have the time. I fiddled around with it a bit and then gave up since the GNU tools worked pretty quick.

Ralph, I'm trying to add an assembler word and trying to deduce register. usage. Could you verify for me please. It looks like the top cell on the stack is actually a register (r6). The second cell on the stack is pointer to by r7. This means that (...) (24 years ago, 19-May-00, to lugnet.robotics.rcx.pbforth)
