Sven Schreiber a écrit : implement. program that I don't know any econometric program doing this. But Gretl is unique isn't it? However, there is plenty of other softwares doing it (eg. Advanced Grapher --a stuff that plots functions' graphs--, just to mention one). The idea behind is very simple and the implementation doesn't need a time-expensive effort I guess (at least in Visual Basic programing : I tried it myself). The language file would be a plain ASCII text file provided with the program. The advantage is that anyone can easily modify e ".txt" file and obtain his own "language file" without waiting an "official" transalation or even to correct or tune it. Actually, doing this with Gretl is somehow troublesome: I guess you have to modify the ".mo" file and I'm not sure if one have to re-compile Gretl for changes taking effect! Anyway, I have no idea how one can make Gretl speak his language. artur Créez votre adresse électronique prenom.nom(a)laposte.net 1 Go d'espace de stockage, anti-spam et anti-virus intégrés.
