GnuDOS library version 1.8: ASCII

8 The ASCII character table

ASCII stands for ’American Standard Code for Information Interchange’. It’s a 7-bit character code used to be the standard of text representation. Although there are a number of other standards in use today, especially those that support wide characters and multi-language interfaces, the ASCII character set is the base for most of the character encodings used today.

The first 32 (0-31) characters in the ASCII-table are unprintable control codes that are classicaly used to control peripheral devices such as printers.

Codes 32-127 are the printable characters, which represent letters, digits, punctuation marks, and a few other symbols. Almost every character is available on standard keyboards. Character 127 represents the command DEL.
