mixed up with the basic tokens. See the tables below (characters marked
white are createable with the keyboard).

Hints if you want to build a converter:
-
The characters A - Z and 0 - 9 may be converted
to ASCII code by calculating Sharp code minus sixteen.
-
All other characters must be converted with a table, I can't see any conversion
system here.
-
The characters Pi, Sqrt and Exp may be a problem,
because there is no equivalent code in ASCII.
-
The BASIC functions ASC and CHR$ are handling the ASCII code,
not the Sharp code.
