and among the errata is this, on "fpldnldbi"

Actually, I believe that there are a couple of other errors in the
description of fpldnldbi on page 152.  Much earlier in the book, on page
52, we are told that fpldnldbi is equivalent to wsubdb followed by
fpldnldb. My own trials have shown that page 52 is correct. On page 152,
therefore, we should have
    Areg' = Creg
    Breg' = undefined
    Creg' = undefined
[whereas the book actually says
    Areg' = Breg
    Breg' = Creg
    Creg' = undefined]
