an old-style ASCII graphic set descended from the default typewheel on
the venerable ASR-33 Teletype (Scandinavians, for whom Ø 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? _________________________________________________________________ Node:1TBS, Next:[215]120 reset, Previous:[216]0, Up:[217]= 0 = 1TBS // n. The "One True Brace Style"; see [218]indent style. _________________________________________________________________ Node:120 reset, Next:[219]2, Previous:[220]1TBS, Up:[221]= 0 = 120 reset /wuhn-twen'tee ree'set/ n. |
