he ASCII-code (American Standard Code for Information Interchange) is 
a 7-bit code, and thus comprises 128 characters. The eighth bit can 
either be set to zero, or used for extensions (characters above 128 
however are no longer standardized) or for parity. In the latter case 
it would make all (2n+1) bit-errors recognizable.

The code is defined as follows:

 Hex  Dec  ASCII  Hex  Dec  ASCII  Hex  Dec  ASCII  Hex  Dec  ASCII

Note: Further important codings are the BCD code, EBCIDIC, UNICODE, as 
well as ISO-Latin (an 8-bit font with european accented characters 
etc.). The characters between 32 and 127 of the ASCII-code correspond 
to the definitions of the Atari system character set.
