The UNPROTECT command, whose syntax is

	.UNPROTECT filename

allows any logged-in user to change the protection of any file on the
disk to 005, which allows any logged-in user access to the file.  The
use of this command is logged on the console terminal and in the file
UNPROT.LOG[1,2], which is otherwise not writeable and cannot itself be
unprotected.  The command is intended as a last-resort emergency
technique for legitimate access to protected files, and its misuse is a
serious offense.  User file directories cannot be unprotected, and a
protected directory will prevent access to any of the files in it.

Note: You should never need this command to unprotect one of your own
files, or one in a directory which you have ACCESSed.  Use the RENAME
monitor command, the ⊗XRENAME command in E, or the ⊗π command in DIRED
in this case.  If you are logged in as [1,PRG] and cannot unprotect a
file in some directory [PRJ,PRG], you should set the MAS access bit in
that directory using the UFD command.
