Good point.

I fail to see why we could not do a parallel.

Just for the record: although the most widely known usage is definitively
hexadecimal notation using A through F, the letters A to Z (or a to z,
depending of variying factors) for the "digits" above 10 in base 11 to 36
are in wide use in the 80's programming languages, including in the
ISO standards for Ada (the base#...# notation) or C (the strtol function,
and the non-Standard itoa/ultoa functions).

Agreed, except that the last two "digits" should be "d" for 10,
and either "u" or "o" for 11!

If it is the way to go, I believe digits 12 to 15 are to be included
as well, due to their usage at least as wide as 10 and 11.
