is that of definition: What, exactly, is the character set?
In order to guarantee a certain amount of machine independence,
the character set we will use here is the set of characters writ-
able as escape sequences in C, plus those characters used in writ-
ing C programs, i.e.,
letters:
ABCDEFGHIJKLMNOPQRSTUVWXYZ 26
abcdefghijklmnopqrstuvwxyz 26
numbers:
0123456789 10
special characters:
~!"#%&()_=-^|{}[]+;*:<>,.?/ 27
extra special characters:
newline \n
horizontal tab \t
backspace \b
carriage return \r
form feed \f
backslash \\
single quote \' 7
blank & NUL 2
---
98

characters. */

of the character in the machine's character set, there should
