You can enter an MS-DOS command when you see the

MS-DOS command prompt. Type the command name and any

necessary parameters and delimiters, and then press Enter to

execute the command. You can type command names in either

uppercase or lowercase letters.

If you make a mistake when typing a command and you notice

it before you press Enter, you can do one of two things:

Use the backspace key to back up and correct the error

Press Esc to cancel the command line.

If you press Enter when a command line has an error in it, the

screen displays an error message. Usually, the command prompt

reappears so you can try again. Type the correct command and

press Enter.

You store all your work and programs in files on your hard disk

or diskettes. A data file contains information, such as words,

numbers, or pictures. A program contains instructions that the

computer can understand and execute.

The kind of file you create depends on the MS-DOS commands

or application program you use to create it. Because each

program you use stores data files in its own particular format,

you are likely to encounter problems if you try to read a file

using a different program.

Each file must have a unique filename so that MS-DOS can

find it when you need to retrieve it. The filename consists of

two parts, the name and the extension.
