Yes, now that we are on the same page, the CONSTANT case is an example
of a case where the addressed data will not change (that's the intent
of the programmer); how can the programmer let the compiler know about
that?  In this case one can define the word with : instead of
CREATE...DOES>, but in general, we may want a way to tell the
compiler that the data in an area is not going to change.
