Hi, I'm doing a rolling regression.

And who can help me with the command to open up an existing workfile?

I creat a workfile named united first, then import an excel of data into the workfile.

Then I create a program and type the code into the program. But I don't know how to open up an existing workfile in the program or just make the program use the data in my exsiting workfile to do the rolling regression.

Thank you so much!

thank you so much!
