File and Device Protection Commands
The following information applies to password protection.
• You can set both read/write and write passwords for a resource. If both
passwords are set, the read/write password has precedence over the write
password.
• If you attempt to password-protect a non-existing resource, the PJL
interpreter will return a warning (CODE = 25001).
• If a resource has already been password protected, the resource must be
“unlocked” before you can specify a different password for that resource.
• Several restrictions with passwords apply to flash due to the nature of the
technology:
— You can create/change passwords for the whole flash multiple times, but
each change uses up free space in the flash that can only be recovered by
reformatting the whole flash.
— You can create passwords for individual resources on the flash only once.
You can also delete this password once. If this is done, you must recreate
the resource before using the password feature again.
Protecting a File or Device
Use the DEFAULT command to set a password on the entire flash or disk or on an
individual macro or font in flash.
Password Protection for a File
LRWLOCK with DEFAULT specified locks a file or device for reading and writing.
LWLOCK with DEFAULT specified locks a file or device for writing only.
