Starting an Application Program
Once you have loaded MS-DOS, you can start using your
application program. If you have already copied the application
program to the hard disk, log onto drive C (and the appropriate
directory, if necessary). Then just enter the necessary command
to start the application program, as described in the program’s
manual. From this point on, until you return to the MS-DOS
command prompt, refer to the application program manual for
any instructions on using the program.
Using Drive Designators
MS-DOS uses letters to identify the disk drives in your
computer. If you have one diskette drive, it is known as drive
A. If you have two diskette drives, the top one is called drive A
and the bottom drive is B.
MS-DOS identifies the hard disk as drive C, even if you have
only one diskette drive.
