The Exit command of the File menu terminates the Spiral program.
If there is a project currently open and if it has been modified, then the program will display the Save Changes dialog window and ask if you wish to save those changes, discard the changes, or if you wish to abort the termination of the application. The Save Changes dialog window is illustrated in Figure 5.2.
The Spiral program can be terminated in the same way as all Windows programs by double clicking on the system menu box or by selecting the Exit command.
