SPSS (Statistical Package for Social "Sciences") uses (used?)
the letters A-X in addition to digits 0-9 for its "portable" file
But I agree that the customary use of A-F for hexadecimal makes
it more difficult to read. I stuck with octal for many years because
of this before giving up to the tide of the culture, even taught my
nephews. Octal is so much simpler, just like decimal if you have
no thumbs, as Tom Lehrer sang.
Tengwar has only twelve digits, but it looks like it would be easy to
hexadecimalize. Just add another curl to eleven to get the digit for twelve.
Then an upside-down ten is thirteen, an upside-down eleven is fourteen, and an
upside-down twelve is fifteen. The only "problem" with tengwar digits is the
units are on the left. What I like about tengwar digits is they come with
their own base marks, so they are ideal for doing math in different number
bases. For hex numbers, a good base mark might be hats or something.
