Many words mentioned above, such as immediate or
set-optimizer change the “current” or “most recently
defined” word. Sometimes you want to change an earlier word. You
can do this with
make-latest ( nt – ) gforth-1.0 “make-latest”
Make nt the latest definition, which can be manipulated by
immediate and set-* operations. If you have used
(especially compiled) the word referred to by nt already, do
not change the behaviour of the word (only its implementation),
otherwise you may get a surprising mix of behaviours that is
not consistent between Gforth engines and versions.
