246.0. "O's and 0's" by PABLO::RECKARD () Wed Sep 24 1986 14:41

Not sure if this is truly "LEX"ish, but is there a DEC standard (oxymoron)
    for the shapes of the letter O and the numeral 0?  For the longest
    time (and my VT240 supports me in this) I thought the letter O was
    almost square and the numeral 0 was narrower and more ovoid(?).
    Lately I've been seeing - output from printers - the reverse.
    Can anyone clarify?

    This may or may not be relevant, but the 0 and the O have a long
    and convoluted antagonism with computers.
    
    Remember the "slash" convention? which circle gets the slash, the
    Oh or the zero? It has been either at various times, depending on
    which was being used less at the time.
    
    So, what I'm saying is that I doubt that anyone can really "clarify"
    this issue. I know I can't.

    re: .1

    IBM FORTRAN IV users put slashes through their letter O's.  HP2000
    users slashes the zeroes.  Since I had to migrate between the two
    for a time, I had a terrible identity crisis...
    
    What about the LN01/LN03 queues?  Or did the system manager name
    them LNO1/LNO3??  I was on two systems once where the system manager
    had named them differently on each system.  The users finally
    threatened mutiny and death.

    Some of the early manuals for the "el en oh three" were printed
    LNO3. The order entry system, however, refused to accept that number!
    
    DIGIAL is trying [very trying!] to achieve at least a difference
    between oh and zero, usually with a square oh and a oval zero. The
    slash was dropped some time ago when the international � and � were
    adopted. 
    
    For typeset fonts we are also identifying which fonts contain the
    LEAST AMBIGUITY.  For example, in italics, the 1's and l's and I's
    are almost always distinct from each other!
    
    This is an important issue and can also be addressed in RAJA::FONTS,
    if you would like to add that conference to your list.

    Many years ago, when I first entered the world of computers, I was
    told by an old hand about a certain line printer.  It could only
    print 32 separate graphic characters.  To save 4 positions (26 upper
    case letters + 10 digits = 36), the 'O' doubled as '0', the 'I'
    as '1', and by clever design, the 'S' as '8' and the 'G' as '6'.
    
    This printer was used to print payroll advices, and worked fine,
    until one day a MISS S SPIGGS joined the company ...

    If the printer you saw the new 0s and Os was an LA75, that was
    apparently (according to the response we got when we commented on
    the O/0 format) an error which is being corrected.

    re: La75 - this printer is a buyout being done as an "emulation"
    of the ___ ProPrinter and not designed according to our font standards.

    Re .3 Before it was revised, the metasyntax of Algol 68 required
    the use of an italic full-stop!
