- /* File : strings.d/ascii.h
- Author : Richard A. O'Keefe
- Updated: 28 April 1984
- Purpose: Define Ascii mnemonics.
-
- This file defines the ASCII control characters. Note that these
- names refer to their use in communication; it is an ERROR to use
- these names to talk about keyboard commands. For example, DO NOT
- use EOT when you mean "end of file", as many people prefer ^Z (if
- the Ascii code were taken seriously, EOT would log you off and
- hang up the line as well). Similarly, DO NOT use DEL when you
- mean "interrupt", many people prefer ^C. When writing a screen
- editor, you should speak of tocntrl('C') rather than ETX (see the
- header file "ctypes.h").
