Function
CPS
CPS(114) compares the signed binary data in S
Greater Than, Greater Than or Equal, Equal, Less Than or Equal, Less Than, and Not Equal Flags) in
the Auxiliary Area.
CPSL
CPSL(115) compares the double signed 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.
