Comparing 16-bit binary data band
ZCP(P)(_U)
These instructions perform a comparison operation on the 16-bit binary data in the device specified by (s1) and the 16-bit
binary data in the device specified by (s2) with the 16-bit binary data in the device specified by comparison source (s3), and
output the comparison result (below, within zone, above) to the device specified by (d) onwards.
