Huh? Yes.

To repeat, I said the length byte of a counted string in
Forth isn't set by the user or programmer.

How can you disagree with that? ...

I have idea what you C answer or explanation below has
to do with Forth's counted strings or your disagreement
with my statement on Forth.

C wasn't even mentioned here ...

I really don't understand why you posted a C explanation to a Forth
statement that you disagreed with.  I almost think this was in regards
to another post on using C style strings for my Forth.
