        I want to write some patches to the system code, so that my
own routines can be called before the 'standard' ones.  I need
to know how to do this, but so far I haven't been able to work
out how best to do it (INIT or Resedit the system (the routines
that I want to hack are in RAM)), I would also like to see an
example - I wouldn't mind somebody else writing the code (but that's
another problem ;^) ).

        Any pointers anyone ?


(PS I am not trying to make myself willfully different, I am trying
to patch in some additional functionality - hence please no
lectures on why I *shouldn't* hack the system. )
