BTW, I've fixed the strlen code (although differently). I didn't know about SALC! That's a very clever way of zeroing AL.

I think at this point I might be able to get away with CLD since I never STD any more :)

Some of the obvious tricks it misses are probably because they're not obvious to me, while others may be just because I haven't gotten to them yet.

Your way is much cleaner; mine was just a size gimmick. I just can't resist it :)
