In the Load a File dialog box, if you choose the Open button instead of the Replace button, Borland Pascal opens a new Edit window and places the selected file in that window.

If you choose Replace, the selected file replaces the file that's in the active Edit window instead of opening in a new window.

Once you've typed in or selected the file you want, choose the Open button (choose Cancel if you change your mind).

You can also just press Enter once the file is selected, or you can double-click the file name.
