Just a quick note to say that the meaning of the term "word" is somewhat
architecture-dependent. The standard M68000 (and thus, Amiga) definition
is "word == 16 bits", except for AmigaDOS ("word == 32 bits") due to some
interesting BCPL implementation issues. M88000 guys have a different definition
(32 bits), as do DEC-20 guys (36 bits), as do... etc.
Of course, I'm sure Larry understands all this; he was just the last
reply to this topic in today's news batch, so he gets picked on.
