Hi Allin and all, I have a need to loop through quit a few .gretl files, but found that I can’t do that like I do with .gdt files. As I tried to figure out why, instead of looping .gretl files, if I just using a script to open one of them, there is a message about: “Opening a new session file will automatically close the current session. Any unsaved work will be lost. Proceed to open session file?” There seems to be no way to turn off this warning. Any suggestion? Fred
