ASCII table (which stands for American Standard Code for Information Interchange) is a character encoding standard for text files in computers and other devices. ASCII is a subset of Unicode and is made up of 128 symbols in the character set. These symbols consist of letters (both uppercase and lowercase), numbers, punctuation marks, special characters and control characters. Each symbol in the character set can be represented by a Decimal value ranging from 0 to 127, as well as equivalent Hexadecimal and Octal values.

The following is a listing of ASCII values displaying the Decimal, Hexadecimal, Octal and Character values for each ASCII character.

In the ASCII character set, the Decimal values 0 to 31 as well as Decimal value 127 represent symbols that are non-printable. It is possible to generate these non-printable characters using a key sequence where ^ represents the control key on your keyboard. For example, you could generate a carriage return (Decimal value 13) by pressing the control key followed by the letter M on your keyboard (^M).

All other symbols in the character set can printed or represented on the screen. These printable character values can be seen in the Char field in the table above.
