I have already found and corrected 2 unbalanced situations using your
system.

This is usefull to check a master word or Window message, and if there is a
problem, to use your balance checker to verify composant words (using the
following on/off system).

    0 VALUE (CHECK-BALANCE)

    : SBAL-ON ( -- ) TRUE TO (CHECK-BALANCE)
        STATE @ ABORT" not in definition" ; IMMEDIATE

    : SBAL-OFF ( -- ) FALSE TO (CHECK-BALANCE)
        STATE @ ABORT" not in definition" ; IMMEDIATE

    : (
       STATE @ IF FIRST? (CHECK-BALANCE) AND IF ...
       ...

I don't know how many hours I have already saved, possibly days.

Great Thank you,
Charles
