I'm writing a program for the PIC16C57 and having some strange
problems.

Basically, I can't seem to write any code past address 200h
(IOW, I can't write more than 512 words of code) without the
program behaving very strangely.  When my program is 511
words (last instruction at 1FFh), it works fine.  Then when
I add a couple of NOPs anywhere in the program to push the
code over the 200h boundry (past the 512-word boundry), it
starts doing all sorts of odd things.  Note that the program
does not crash, it just behaves strangely.

Anyway, I would expect this type of behavior from, say, a
PIC16C54 which has only 512-words of code space.  But I'm
using a C57, which is supposed to have 2K.

After banging my head against the proverbial wall for a
while, I finally remembered that the PIC has 512 word pages.
So I was thinking that maybe there is something special you
have to do to move into another page.  And the more I think
about it, the strange behavior I'm getting seems to be
similar to the type of behavior I would expect if the last
couple instruction words were getting cut out of my program.
So can someone help me:  is there something special I need
to do after my code spills over onto a second page?

Thanks for any help.  It will be greatly appreciated.
