Hi Marcel,

I cannot find a reference for CHOOSE. I assume that you are not talking
about Leo Brodie, as I cannot find a reference to this word in my
edition Starting Forth Hardcover edition 1984, Forth Inc. nor Thinking
Forth (CC Print Edition 2004).

Yeah, I have had used QUIT in serveral instances first. BYE is a bit
rude indeed.

Yes, I did not (or failed to) check this. The CSP(?) words mentioned in
other articles is a neat trick as a final safe guard against this kind
of error.

A right! I ran across page while seeing through editor words, but missed
AT-XY somehow.

right.

All true.

Thank you!
