  I assume that you are confusing the SHR *logical* instruction with
the DIV or IDIV *arithmetic* instruction. I agree that the numbers you
end up with may be different if you do bit-shifts, but not the bits.

  But you are saying the opposite... that doing a SHR instruction may
not give you a bit-shift. You may be correct, I don't know, but on
your past performance it would be dangerous for me to take what you
say as gospel. All I can do is file what you say under "Paul Edwards
Information" in my brain and see how it turns out.
