Comparison Instructions Section 3-6
Example When CIO 0.00 is ON in the following example, the eight-digit unsigned binary
data in CIO 1001 and CIO 1000 is compared to the eight-digit unsigned
binary data in CIO 1501 and CIO 1500 and the result is output to the Arith-
metic Flags. The results recorded in the Greater Than, Equals, and Less Than
Flags are immediately saved to CIO 100.00 (Greater Than), CIO 100.01
(Equals), and CIO 100.02 (Less Than).
3-6-5 SIGNED BINARY COMPARE: CPS(114)
Purpose Compares two signed binary values (constants and/or the contents of speci-
fied words) and outputs the result to the Arithmetic Flags in the Auxiliary Area.
