        A dictionary containing a natural history requires too
        many hands, as well as too much time, ever to be hoped
        for.                                        --Locke.
  0 \0\ adj.
     1. indicating the absence of any or all units under
        consideration; -- representing the number zero as an
        Arabic numeral
  
     Syn: zero
          [WordNet 1.5 +PJC]

  0 Numeric zero, as opposed to the letter `O' (the 15th letter of the
     English alphabet). In their unmodified forms they look a lot alike, and
     various kluges invented to make them visually distinct have compounded
     the confusion. If your zero is center-dotted and letter-O is not, or if
     letter-O looks almost rectangular but zero looks more like an American
     football stood on end (or the reverse), you're probably looking at a
     modern character display (though the dotted zero seems to have
     originated as an option on IBM 3270 controllers). If your zero is
     slashed but letter-O is not, you're probably looking at an old-style
     ASCII graphic set descended from the default typewheel on the venerable
     ASR-33 Teletype (Scandinavians, for whom /O is a letter, curse this
     arrangement). (Interestingly, the slashed zero long predates computers;
     Florian Cajori's monumental "A History of Mathematical Notations" notes
     that it was used in the twelfth and thirteenth centuries.) If letter-O
     has a slash across it and the zero does not, your display is tuned for a
     very old convention used at IBM and a few other early mainframe makers
     (Scandinavians curse _this_ arrangement even more, because it means two
     of their letters collide). Some Burroughs/Unisys equipment displays a
     zero with a _reversed_ slash. Old CDC computers rendered letter O as an
     unbroken oval and 0 as an oval broken at upper right and lower left. And
     yet another convention common on early line printers left zero
     unornamented but added a tail or hook to the letter-O so that it
     resembled an inverted Q or cursive capital letter-O (this was endorsed
     by a draft ANSI standard for how to draw ASCII characters, but the final
     standard changed the distinguisher to a tick-mark in the upper-left
     corner). Are we sufficiently confused yet?
