To put it simple, carry occurs when the processor tries to put a value in a
register that is bigger than that the register can hold.
you can also think of it as a bit on step more significant than the most
significant bit.
so when modifying a byte, carry is bit 8. When modifying a word, its bit 16.

and compares is simply subtractions that only affects the flags, without
modifying the registers..
