[Gretl-users] Re: Re: GRETL Feature Suggestion (Allin Cottrell)

Great! One more reason to use Linux (I have a dual booting machine and test both Linux and Windows versions) This way of defining new variables doesn't look so bad. I guess I can better my computing habits by learning this method of handling data. This actually looks more powerful. You are right. There are probably much more important things to worry about. Still, this might be a nice addition in the longrun since the spreadsheet is already there and it actually looks pretty decent even without features.
