3.Now press F6 and then Enter. COPY creates a file named AUTOEXEC.BAT and copies everything you just typed into that file. The AUTOEXEC.BAT file is stored in the root directory of your hard disk. From now on, the AUTOEXEC.BAT program is executed every time you load MS-DOS-which means every time you start or reset your computer.

Starting an Application Program

Any time you see the MS-DOS command prompt (A> or C>, for example), you can start using an application program. Just log onto the drive and directory containing your application program files (if necessary) and type the name of the program’s executable file. (See the documentation for your application program if you are not sure what to type.) When you press Enter, MS-DOS begins running the application program. When you exit the program, the MS-DOS command prompt reappears. Be sure to exit the application program properly and return to the command prompt before turning off your computer.

Using the LIGHTON Utility

If you use memory-resident programs such as desktop accessories or the MS-DOS KEYB command, you may find that you cannot turn on the screen’s backlighting once it has automatically turned itself off. If this happens, save any data files you are working on and reset your computer.

You can prevent this problem from occurring by using the Epson LIGHTON utility (on your Reference diskette). First load your memory-resident program, then enter the LIGHTON command (type LIGHTON and press Enter); this order is important. Another solution is to run the Backlight period portion of the setup program (see Chapter 2) and select No time limit.
