The SET Command CP/M 3 User's Guide
The second SET command disables password protection for the files on
your disk.
After a password is assigned to the label and the PROTECT option is
turned on, you are ready to assign passwords to your files.
You can always determine if a disk is password-protected by using the
SHOW command to display the label.
Assign Passwords to Files
Syntax: SET filespec[PASSWORD =password]
Explanation: The preceding SET command sets the password for filespec to the password
indicated in the command tall. Passwords can be up to eight
characters long. Lower-case letters are translated to upper-case.
You can use wildcards in the filespec. SET assigns the specified password
to the files that match the wildcard-filespec.
Note: always record the passwords that you assign to your files.
Without the password, you cannot access those files unless password
protection is turned off for the whole disk. If you forget the password
to the directory label, you cannot turn off the password protection for
the disk.
Example: A>SET MYFILE.TEX[PASSWORD=MYFIL]
MYFIL is the password assigned to file MYFILE.TEX.
