This command is used to set the file password and to toggle the password protection state. Password protection enables protection at the level of the file system, and is used to prevent an end user of the system from deleting or retrieving a file. Password protection is available for each file individually. By entering a password, the protected state is enabled. The state can be returned to the unprotected state by again entering the password. Any password entered while in the unprotected state returns the file to the protected state, with the password being the string that was just entered. A password can be changed by following this procedure. The password protection mechanism does not affect the ability to load and run the task.
