Multiple datasets in memory in Stata 16 You can now load multiple datasets into memory. You type . use people and people.dta is loaded into memory. Next, you type . frame create counties . frame counties: use counties and you have two datasets in memory. people.dta is in the frame named default, and counties.dta is in the frame named counties. Your current frame is still default. Most Stata commands use the data in the current frame. For example, if you typed . list then people.dta will be listed. If you typed . frame counties: list then counties.dta will be listed. Or you could make counties the current frame by typing . frame change counties and list will now list the counties data.
