[Gretl-users] Deleting variables

Dear Gretl Community, I have 100 series inside my series (a .gdt file) and I would like to delete all the series that I don't need. I know how to do this using the GUI or with the command "delete", but I would like to make it in a more automatic way. For example, I would like to use the series 5, 8, 37 and, 98 and delete anyone else. Please take a look in this pseudo-code: list Y = 5 8 37 98 if the variable is on the list make nothing else delete variable endif Best regards, -- Henrique C. de Andrade Doutorando em Economia Aplicada Universidade Federal do Rio Grande do Sul www.ufrgs.br/ppge
