If you know the words, it is not difficult to access them.

If you don't know the words, you can find them (using Ladislav's
functions) as long as they are in system/words. If the programmer
has played some tricks so that the used words have not been added
to system/words, I think that you are out of luck.
(Anyway, as long as a word is not accessible in any way, there is
no point in trying to serialize it, as it wouldn't have any effect
on the execution of the serialized script...)
Regards,
Gabriele.
