Though we can play Reversi, we cannot save games in progress and resume play at a later date. In this section, we add a save feature to the game, available through Save, Save As and Open commands on the File menu. (If you look at the version of Reversi we have at the moment, you will see that those items are disabled.)
The code we will add to implement the save feature has a small bug that we must correct before the feature will work properly. In doing so, we will see the editor, debugger, and browser tools.
