Abstract
The data compressor utilizes a plurality of character tables arranged in levels for storing strings of data characters, the character tables corresponding to respective characters of the alphabet. A string is stored by storing the string code associated with the string in a character table corresponding to the extension character of the string in a location of the character table corresponding to the code of the string prefix. The character tables at the first level store 2-character strings and the character tables at a subsequent level store strings that are one character longer than the strings stored in the character tables at the level prior thereto.
