Casio CZ/ VZ/ FZ - Pro Series

i was joking ,
 how can you analyse a nybble without putting into a byte.or allready having
it in a byte ..... thats the joke

asl asr lsl lsr shl shr  &hxxxx0000   bitwise arthicmitic functions
masks and   AND or OR or MODULO

i dont have much time right now , but i do have a list of projects to
complete so when i return
i shall bring the answer.

charlie  about the checksum
