Abstract
Disclosed is a method of decompressing data mode up of a sequence of literal references, history references, and lexicon references. The method includes the steps of reading a reference from the sequence and emitting a lexicon string if the reference is of the type lexicon, emitting a history string if the reference is of the type history, and emitting a literal string if the reference is of the type literal. The string emitted is inserted into a history buffer and if the string is of the type history it is inserted in a lexicon.
