Table 5-17. Password Protection Modes
Mode Protection
READ The password is required for reading, copying,
writing, deleting, or renaming the file.

renaming the file. You do not need a password to
read the file.
DELETE The password is only required for deleting or renaming
the file. You do not need a password to

Assign a Default Password
Syntax: SET [DEFAULT = password]
Explanation: The preceding set command assigns a default password for the system
to use during your computer session. The system uses the default password
to access password-protected files if you do not specify a password,,
or if you enter an incorrect password. The system lets you access
the file if the default password matches the password assigned to the
file.
Example: B > SET *.TEX[PASSWORD = SECRET, PROTECT = WRITE]
The preceding command assigns the password SECRET to all the TEX
files on drive B. Each TEX file is given a WRITE protect modc to
prevent unauthorized editing.
