<CORE>
return the execution token of the following name. This word
is _not_ immediate and may not do what you expect in
compile-mode. See ['] and '> - note that in FIG-forth
the word of the same name had returned the PFA (not the CFA)
and was immediate/smart, so beware when porting forth-code
from FIG-forth to ANSI-forth.
