Il y a quelque chose que j'ai pas compris ? faut-il définir tous les mots du langage obligatoirement dans le lexique ?

L'erreur : error(50): c.g4:80:0: syntax error: unterminated rule (missing ';') detected at 'FileDecl :' while looking for lexer rule element
et du même genre
error(50): c.g4:61:0: syntax error: unterminated rule (missing ';') detected at 'Instruction :' while looking for lexer rule element

que veut dire exactement ?

Merci d'avance pour toute aide.
