lexical analysis
     
         (Or "linear analysis", "scanning") The first
        stage of processing a language.  The stream of characters
        making up the source program or other input is read one at a
        time and grouped into {lexeme}s (or "tokens") - word-like
        pieces such as keywords, identifiers, {literal}s and
        punctutation.  The lexemes are then passed to the {parser}.
