Function
 ZCPS
ZCPS(117) compares the 16-bit signed binary data in CD with the range defined by LL and UL and
outputs the result to the Arithmetic Flags.
 ZCPSL
ZCPSL(118) compares the 32-bit signed binary data in CD+1, CD with the range defined by LL+1, LL
and UL+1, UL and outputs the result to the Arithmetic Flags.
