The ASCII Character Set - Arizona State University
The ASCII Character Set
The American Standard Code for Information Interchange or ASCII assigns values between 0 and 255 for upper and lower case letters, numeric digits, punctuation marks and other symbols. ASCII characters can be split into the following sections:
0 ? 31 32 ? 127 128 ? 255
Control codes
Standard, implementation-independent characters
Special symbols, international character sets ? generally, non-standard characters.
Control Codes : ASCII Characters 0 - 31
The following table lists and describes the first 32 ASCII characters, often referred to as control codes. The columns show the decimal and hexadecimal ASCII values for each code along with their abbreviated and full names. Descriptions are given to those most in use today.

Characters 128 - 191
This first table contains characters 128 - 191, abstract symbols that appear in text from time to time.
