WIth regard to TRUE FOO C! FOO C@ : The value on the stack at the end of the
sequence will not be a  well-formed flag unless the size of a character and
the size of a  cell are the same (odd, but legal).  On any ASCII Standard
system  (assuming we get there)  the result would be treated by IF as true.

Citing 4.0790 true : " A 'true' flag returned by a standard word is a  single-
cell value with all bits set."   The above construct therefore  can not be
used by itself to leave a flag after a system word.  It  _would_ be legal in a
standard _program_.
