ASCII                 Technical Information                 ASCII




ASCII is  an acronym for the American  Standard Code for Informa-
tion Interchange.  It is a table of seven-bit binary numbers that
encode the  letters of  the alphabet, numerals,  punctuation, and
the most  commonly used control  sequences for printers  and ter-
minals.  ASCII  codes are used on all  microcomputers sold in the
United States.

The following table gives the ASCII characters in octal, decimal,
and  hexadecimal  numbers,  their  definitions, and  expands  ab-
breviations where necessary.
