To change the default drive, type the letter of the drive you want to

change to, followed by a colon. Then press 

Enter. 

For example, to

change the default from A to C, type C : and press 

Enter. 

MS-DOS

acknowledges the change by displaying the command prompt C >.
Changing to a new drive is also sometimes called logging onto that

drive.

To access a program or file without first changing the default drive,

use a drive identifier with the filename. For example, if you are logged
onto drive A and type B : PROGRAM, MS-DOS loads and executes the
file named PROGRAM from drive B but stays logged onto drive A.

To enter an MS-DOS command, you need to type the command in

the correct format. The command format provides MS-DOS with the

information needed to perform a task.

The MS-DOS command format consists of the command name,

parameters, and delimiters. The command name tells MS-DOS the
task you want the computer to perform. Parameters specify details

such as what data you want to process and where to locate or store a

file. Delimiters are characters such as spaces or commas that separate

command names and parameters.

For example, the command to format a diskette in drive A is:

FORMAT A:

FORMAT is the command name to execute the file FORMATCOM.

The A: is a parameter that tells the command what to format-in this

case, the diskette in drive A. The space between FORMAT and A: is

the delimiter that lets MS-DOS distinguish the command name

(FORMAT) from the parameter (A:).
