Comparison Instructions
Section 3-7
Description
ZCP(088) compares the 16-bit signed binary data in CD with the range
defined by LL and UL and outputs the result to the Greater Than, Equals, and
Less Than Flags in the Auxiliary Area. (The Less Than or Equal, Greater
Than or Equal, and Not Equal Flags are left unchanged.)
Arithmetic Flag Status
The following table shows the status of the Arithmetic Flags after execution of
ZCP(088).
Using ZCP(088) Results in the Program
When ZCP(088) 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 ZCP(088), as shown in the following dia-
gram. In this case, the Equals Flag and output A will be turned ON when
