ASCII(7)

NAAM
ascii - ASCII tekencodering, gecodeerd in octaal, decimaal en hexadecimaal

BESCHRIJVING
ASCII is the American Standard Code for Information Interchange. It is a 7-bit code. Many 8-bit codes (e.g., ISO 8859-1) contain ASCII as their lower half. The international counterpart of ASCII is known as ISO 646-IRV.

De volgende tabel bevat de 128 ASCII tekens.

C program '\X' escapes are noted.

OPMERKINGEN

  Geschiedenis
Een ascii man pagina verscheen in versie 7 van AT&T UNIX.

On older terminals, the underscore code is displayed as a left arrow, called backarrow, the caret is displayed as an up-arrow and the vertical bar has a hole in the middle.

Uppercase and lowercase characters differ by just one bit and the ASCII character 2 differs from the double quote by just one bit, too. That made it much easier to encode characters mechanically or with a non-microcontroller-based electronic keyboard and that pairing was found on old teletypes.

De ASCII standard werd gepubliceerd door de United States of America Standards Institute (USASI) in 1968.
