Comparison Instructions
Section 3-7
Description
ZCPL(116) compares the 32-bit signed binary data in CD+1, CD with the
range defined by LL+1, LL and UL+1, 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
ZCPL(116).
Using ZCPL(116) Results in the Program
When ZCPL(116) 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 ZCPL(116).
Do not program another instruction between ZCPL(116) and the instruction
controlled by the Arithmetic Flag because the other instruction might change
the status of the Arithmetic Flag.
The operation of ZCPL(116) is almost identical to that of ZCP(088) except that
ZCPL(116) compares 32-bit values instead of 16-bit values. Refer to
3-7-11

results in the program and an example program section.
