Making a word current

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.
