When you see the A > prompt, you know that MS-DOS is operating from
drive A. If you want to run a program or find a file on a different drive,
however, you must specify that drive. You can do this either by logging on to

that drive or by including the drive identifier (the drive letter followed by a

colon) when you type the filename.

To log on to drive B, for example, type B: and press 

Enter. 

Your screen

now displays the B > prompt. This means that you are now operating from

drive B as the default drive. The system continues to read from drive B until

you log on to another drive, or turn off or reset your computer.

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 on to
drive A and type B : README within your MS-DOS command, the

computer retrieves the file named README from drive B but stays logged

on to 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, 

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.

Some commands also have optional switces you can use. A switch is a type
of parameter that alters the effect of a command.

Path names may be required in a command if you are specifying files that are

not on the current drive or directory. A path name tells MS-DOS where to
locate a file, and consists of one or more directory names separated by

backslashes. See the section on using pathnames later in this chapter.
