Function
CMP
CMP(020) compares the unsigned binary data in S
(the Greater Than, Greater Than or Equal, Equal, Less Than or Equal, Less Than, and Not Equal
Flags) in the Auxiliary Area.
CMPL
CMPL(060) compares the unsigned binary data in S
Arithmetic Flags (the Greater Than, Greater Than or Equal, Equal, Less Than or Equal, Less Than, and
Not Equal Flags) in the Auxiliary Area.
