CPS(114) compares the signed binary data in S
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.
Note CPS(114) treats the data in S
from 8000 to 7FFF (
Arithmetic Flag Status
The following table shows the status of the Arithmetic Flags after execution of
CPS(114). (A status of "---" indicates that the Flag may be ON or OFF.)

Using CPS(114) Results in the Program
When CPS(114) is executed, the result is reflected in the Arithmetic Flags.
Control the desired output or right-hand instruction with a branch from the
same input condition that controls CPS(114), as shown in the following dia-
