Casio CZ/ VZ/ FZ - Pro Series

hold on is it as simple as taking a 16 bit nuber and using the msb and lsb
of it ? basically dividing it by 256?

or would i do a byte  split  into two separte bytes?

a integer divide by  16
  and
a  X and 15 ???

still tho , anybody have written their own editor for the cz101 at all?

curious
