Learn how to reply properly to email, and you won't make this mistake again.
By top posting, you let yourself loose the context (and made it harder for
others to follow the flow too).  Here is is what your post would have looked
like if written properly:

So hopefully you can now see for yourself that the answer to your first
question is "Danny Miller", and that my comment was clearly in regards to a
PIC 16.  Note that the PIC 16 (14 bit midrange core) is limited to 8K words
of program memory.
