Exemple :

begin class Client
    the class
        has  a Temps_Attente, '' en minutes,
             a Visiter_Banque  process method,
         and a Générer_Client  process method

    define Temps_Attente as a real variable
    tally   Moyenne_Quotidienne_Temps_Attente               as the QUOTIDIEN mean,
            Moyenne_Temps_Attente                           as the mean,
            Histogramme_Temps_Attente (0.0 to 100.0 by 5.0) as the histogram
							of Temps_Attente
    define Générer_Client as a process method
                           given 2 real values  ''la longueur de la journée en heures 
                                                '' la moyenne d'inter-arrivée
