% Table of ASCII encodings (as used by CHAR->ASCII and ASCII->CHAR)

``ASCII'' stands for ``American Standard Code for Information Interchange''.
|
||
|
|
The ASCII standard is a seven-bit code published by the United States of
|
||
|
|
America Standards Institute (USASI) in 1968.
|
||
|
|
The ASCII encoding forms the first half of ISO-8859-1 (Latin1) which in
|
||
|
|
turn forms the first page of ISO 10646 (Unicode).
