However, they have this feudal privilege (that no other gretl citizen has) of being somewhat exempt from the principle of strict localisation. This can be VERY troublesom, at times. Consider this, for example. <hansl> function list moo(void) series you_would_think_this_is_safe = NA list ret = you_would_think_this_is_safe return ret end function # --- main ----------------------------- nulldata 10 # your precious data you_would_think_this_is_safe = normal() # apparently harmless function call moo() print you_would_think_this_is_safe # data are gone! </hansl> I don't know about you, but I find this slightly disturbing. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
