The page that Michael cited: http://www.kcats.org/csci/464/ho/usingtechnique.shtml appears to be (partly) in response to a thread I started on this list years ago. Still, I agree with John, Tony, and bixoft, and disagree with Robin and Binyamin. In my memory, this went by so many years ago that LHI and AHI were not available. Nowadays, AHI might be a better choice. However, availability of a (perhaps) better alternative does not diminish the truth of Tony's assertion, "It's also how 'classic' (base & displacement) addressing arithmetic, which we all know deals only with unsigned values, can subtract."
This is incorrect, because the hardware ADDS only.
