C0 and C1 Control Codes

C0 And C1 Control Codes

Most character encodings, in addition to representing printable characters, may also represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. The C0 and C1 control code or control characters sets define control codes for use in text by computer systems that use the ISO/IEC 2022 system of specifying control and graphic characters. The C0 set defines codes in the range 00HEX–1FHEX and the C1 set defines codes in the range 80HEX–9FHEX. The default C0 set was originally defined in ISO 646 (ASCII), while the default C1 set was originally defined in ECMA-48 (harmonized later with ISO 6429). While other C0 and C1 sets are available for specialized applications, they are rarely used.

Famous quotes containing the words codes and/or control:

    We must trust infinitely to the beneficent necessity which shines through all laws. Human nature expresses itself in them as characteristically as in statues, or songs, or railroads, and an abstract of the codes of nations would be an abstract of the common conscience.
    Ralph Waldo Emerson (1803–1882)

    The child knows only that he engages in play because it is enjoyable. He isn’t aware of his need to play—a need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.
    Bruno Bettelheim (20th century)
