The Technical Note describes some of the properties of the USA Standard Code for Information Interchange, widely known as ASCII or USASCII.It also relates this code to similar international codes and presents the national code for Russia as an example of the worldwide acceptance of this code, which is comprised of seven information bits representing 128 coded characters.Some of the conventions which are evolving to relate these seven bit codes to six and eight bit computer codes are given, and conventions for extending the code to represent an unlimited repertoire of concepts is also given.Two alternate arrangements of the code table are shown to facilitate an understanding of its structure and application.(Author).
