ZCPS --- 117
Compares the 16-bit signed binary value in CD
(word contents or constant) to the range defined
by LL and UL and outputs the results to the Arith-
metic Flags.
DOUBLE SIGNED AREA

ZCPSL --- 118
Compares the 32-bit signed binary value in CD
and CD+1 (word contents or constant) to the
range defined by LL+1, LL and UL+1, UL and out-
puts the results to the Arithmetic Flags.
