Re^3: When I see "10", I think:

Having a separate 1 key was an innovation that came fairly late in the game. Older typewriters didn't have it, and it wasn't until the late 1970s that you could count on it being there. So people were taught to type without it.

Absolutely. My Mum's typewriter had numbers running from 2 till 9, I think. I used a lower case ell for one, and I guess capital oh worked for zero. Which reminds me of a textbook on BASIC where the authors insisted that capital oh was always shown with a slash through it, to differentiate it from zero, which was always displayed without a slash. This is backwards to many implementations, since null and zero are similar concepts. Of course, if you're Scandinavian, and you already have the letter oh with a slash through it. It's always something. . Alex / talexb / Toronto "Groklaw is the open-source mentality applied to legal research" ~ Linus Torvalds	[reply]

Even with certain fonts these days, it can still be a problem. Numeric one, lower case ell, even an uppercase eye can (in some sans-serif fonts like Arial) look very close to the same.	[reply]
