Stata’s Do-file Editor for Windows has been completely rewritten, making programming tasks simpler than ever.
Download Stata from HERE.
Clicking on the Do-file Editor button is equivalent to typing doedit.
Doedit, typed by itself, invokes the Editor with an empty document. If you specify filename, that file is displayed in the Editor.
You may have more than one Do-file Editor open at once. Each time you submit the doedit command, a new window will be opened.
