The article has double aims. Taken Chapter 8 of Le Petit Prince as a basis the authors try to ahow the necessity of introducing some (implicite) completion of the text through a coreferential analysis of a text derived from the mental picture of the relatum. Furthermore, an explicite representation of coreferential relations can be realized by applying certain „coreferential indexes” and it is also shown how the coreferential analysis contributes to the macrocompositional analysis of the text.
