It starts to get pretty useful in conjunction with curses -- for example, in
writing interpreters for character-at-a-time command loops.
I have a new version that adds the following:
\begin{funcdesc}{ascii}{c}
Return the ASCII value corresponding to the low 7 bits of c.
\end{funcdesc}
The following function takes either a single-character string or
integer byte value; it returns a string.
\begin{funcdesc}{unctrl}{c}
Return a string representation of the ASCII character c. If c is
printable, this string is the character itself. If the character
is a control character (0x00-0x1f) the string consists of a caret
(^) followed by the corresponding uppercase letter. If the character
is an ASCII delete (0x7f) the string is "^?". If the character has
its meta bit (0x80) set, the meta bit is stripped, the preceding rules
applied, and "!" prepended to the result.
\end{funcdesc}
Finally, the module supplies a 33-element string array
called controlnames that contains the ASCII mnemonics for the
thirty-two ASCII control characters from 0 (NUL) to 0x1f (US),
in order, plus the mnemonic "SP" for space.

Certainly one of the chief guarantees of freedom under any government,
no matter how popular and respected, is the right of the citizens to
keep and bear arms. [...] the right of the citizens to bear arms is
just one guarantee against arbitrary government and one more safeguard
against a tyranny which now appears remote in America, but which
historically has proved to be always possible.
