Hi Lothar,

Yes, this is a "standalone target". I was having trouble getting the 
serial port to work with gforth 0.7 when I did this and decided not to 
make a tethered target, at least not until the gforth serial problems 
were solved. Since I already had avrdude for downloading and minicom and 
the simple interpreter for testing I wasn't very motivated to solve the 
gforth serial problem. I'm sorry there isn't a manual for this like Bob 
Nash's for the 8051.

That's the target HERE, see the word "report" in compiler.fs for details. 
What's not clear to me right now is whether this is a byte address or a 
word address. I haven't been using this much until just recently. Also 
after typing "t" you can then type "target-words" to see what words have 
been compiled for the target. The target words are in a list of labels 
separate from the targ vocabulary and that list gets tacked on to the end 
of the target dictionary at the end of compilation. The word "words" is 
in the list appended to the target. Execute "words" from minicom and see 
what happens. Press space to continue and return to stop. If only I could 
get Bob to write a manual for this.

Another thing, the "Host stack= <1> 1000" indicates that something was 
wrong. Normally the host stack should be empty. That report is there so 
I'll notice when, for example, I forget to match an "if" with a "then" or 
forget to put # after a number.

Finally, the weird characters you mention come from a bug in the 
interpreter which I recently (I think) fixed. I want to do a few more 
things with it first, but will package up the new version and get it to 
you pretty soon, ok?

Thanks again for the interest,
Charley.
