Abstract
Words and word codes corresponding to the words are registered in advance. If an unregistered word appears when data are compressed, the code of the leading character of the word is divided into a plurality of parts in a specific size, a predetermined additional code is added to generate a code of the same length as the word code. Thus, the compressed data can be treated as fixed length codes. When the compressed data are decompressed, the code of an unregistered character is identified using this additional code.
