Figure 3-4.
The Self-Test prints the uppercase alphabet in the first
line, 10 characters per inch. In Chapter 5, you'll learn how to print larger
and smaller letters (from 5 to 17 characters per inch).

In Figure 3-4, the characters coded "a" and "c" are "brackets:'
These are sometimes used in the same manner as parentheses.
The character coded "b" is a "reverse slash" - the mirror-image
of the "slash" in Figure 3-3. The next character,
"1\ ;'
is a computer
symbol for depressing the "control key" on your keyboard. It can
also be used for a circumflex or exponentiation. Completing this
set of characters, the character coded "e" is the "underlining" for
a single character, and "f" represents the "opening single
quotation" mark.
In Figure 3-5, the "lowercase" equivalents of the "uppercase"
letters in Figure 3-4 are presented. These letters are also 10
characters per inch (CPI) in the Self-Test. Following the lowercase
letters in this figure are four characters coded "a" through Old:' The
first and third are "braces;' which provide an alternative to
parentheses and brackets, especially in grouping mathematical
terms. The symbol coded "b" is a special scientific symbol, to
which you may assign meaning according to its use. Finally, the
character marked "d" is the tilde sign or diacritical mark.
