ASCII Code Chart

The ASCII code scheme was originally developed to get round IBM’s copyright on the EBCDIC scheme. It is now virtually universal, even on IBM computers.

Notes:

  1. The table gives hexadecimal values for the codes, increasing down the columns. So, for example, the code for a capital ‘J’ is 4A16.
  2. Codes less than 2016 (the ASCII code for a space) are non-printing control characters, represented here by 2- or 3-letter abbreviations.
  3. 2D16 is the minus symbol or hyphen, ‘-’. 5F16 is the underscore character, ‘_’.
  4. Codes greater than 7F16 are unused in the ASCII scheme.
