Mike,

I tried to be clear, but it
seems I was not. A discrete
code is a subcategory of
advanced codes, which is to say
that all discrete codes are
advanced codes, but not all
advanced codes are discrete
codes.

What seperates a discrete
advanced code from a
non-discrete advanced code is
that a discrete code selects a
specific device state, such that
it does nothing if the device is
already in that state.

A non-discrete code will cycle
through two or more states, such
that the device state will
always change in some way when
the code is recieved.

Does this clarify matters?
