3.4.4 Comparisons of Integers
Unsigned integers may be compared by testing the zero and carry flags after a subtract
operation. The zero flag is set if the numbers are equal. With the SBC instruction the carry
cleared is set if the number subtracted is less than or equal to the number it is subtracted
from. 8-bit unsigned integers span the range 0–255. 16-bit unsigned integers span the
range 0–65535.
If A is in HL and B is in DE these operations can be performed as follows assuming that
the object is to set HL to 1 or 0 depending on whether the compare is true or false.
