When is it passed to the target?  As soon as the 3 is processed on the
host side?  Or when + is looked up (and found) in the target dictionary?

What happens if you say "2 3 dup"?  Does the host stack still have
"2 3" while the target stack has "2 3 3"?

How do you exhibit the host stack, if most or all of the words like "."
are intercepted by the target dictionary and run on the target instead
of the host?  Are there special host words that are kept from being
redefined for the target somehow?

I had been thinking of having separate host and target windows on the
screen, or something like that.  Maybe that's not Forth-like though.

Thanks as always.
