Dear Gretl Community, When I try to save data (or session, or script) files with dots in the names, using the GUI, Gretl assumes that all the comes after that point is an extension name. Suppose I have to create three files with names that help me to associate them with Chapter 2.5 of my book: Data Chapter 2.5 Session Chapter 2.5 Script Chapter 2.5 I all the examples above Gretl creates the respective file with the extension ".5", instead of ".gdt", ".gretl", and ".inp", respectively. Is this the intended behavior? Um abraço, -- *Henrique C. de Andrade* Doutorando em Economia Aplicada Universidade Federal do Rio Grande do Sul www.ufrgs.br/ppge
