I don't want to implement this kind of extension.
The standard way of writing the null character would be to use
X'' literal like this:
VALUE '...' & X'000000000C'.
However, I haven't implemented the `&' operator (literal
concatenation). Gee.
In any event, \0 is a valid alphanumeric character, so
I'll fix the compiler.
