Comparison Instructions Section 3-6
Operand Specifications for Instructions for Double-length Data
Description The input comparison instruction compares S
1
and S
2
as signed or unsigned
values and creates an ON execution condition when the comparison condition
is true. Unlike instructions such as CMP(020) and CMPL(060), the result of an
input comparison instruction is reflected directly as an execution condition, so
it is not necessary to access the result of the comparison through an Arith-
metic Flag and the program is simpler and faster.
