Walt,
Thanks a LOT for updating the example. Do you mind if I pull the code
from your site, reformat if necessary and include it in the test code
section of my distribution?
You will, of course, retain primary credit in the source file.
This kind of community participation is what really helped bring the
original pbForth to a decent state, and I'm hoping that as some momentum
comes up behind pbLua that the trend continues.

Those results are pretty decent :-) I'll see if I can tweak the code
to run a bit faster...
Formatting displays is expensive because it calls into sprintf(), and
I'd like to optimize the display update so that the refresh code is
called ONLY when something has been written to the display map...
