CMPL(060) compares the unsigned binary data in S
and outputs the result to Arithmetic Flags (the Greater Than, Greater Than or
Equal, Equal, Less Than or Equal, Less Than, and Not Equal Flags) in the
Auxiliary Area.
Arithmetic Flag Status
The following table shows the status of the Arithmetic Flags after execution of
CMPL(060). (A status of "---" indicates that the Flag may be ON or OFF.)
