Dear Gretl Community, I would like ask you two questions: *Question 1* To save a OLS model with a specific name I can use *Example1 <- ols x1 const x2 x3 --robust --quiet*, but if I would like to name the model as Example 1 (with a space between Example and 1), according to Gretl manual, I can write *"Example 1" <- ols x1 const x2 x3 --robust --quiet*, am I correct? When a proceed in that way I get an error message. The only way it works is without the options *--robust --quiet*. *Question 2* Is it possible to insert some instruction on a Gretl script file in order to make Gretl recognize what operational system it is running on? More specifically, I would like to make a script to use on both of my computers (Windows based and OS/X based). Something like this: If the operational system is Windows do this: ... If the operational system is OS/X do this: ... Best regards, Henrique C. de Andrade Doutorando em Economia Aplicada Universidade Federal do Rio Grande do Sul www.ufrgs.br/ppge
