You are about to execute a command that will cause the changes you have made to a loaded file since the last the last time you saved it to be lost. Either: ■ Choose <Yes> to save the file, preserving your changes, and then finish executing this command. ■ Choose <No> to finish executing this command without saving the file. Use this choice to throw away work that you do not wish to save. ■ Choose <Cancel> to stop the command, leaving everything just as it was before you chose this command.
