$! PROT.COM
$! Change protection of a file.
$! GMU	26-Jul-83 20:22	version 1.02
$!
$! This file is invoked via the PROTECT command (PRO*TECT :== @PROT.COM)
$! and takes one paramter as a file spec.  It then asks for the protection
$! codes for each class.  The command invocation looks like:
$!
$!	$ protect foo.bar
$!	$_System: rwed
$!	$_Owner: rwed
$!	$_Group: re
$!	$_World:
$!
$! In answer to the prompt, the user may give the standard codes, as
$! shown above.  In addition, there are three more legal responses.  A
$! "*" (without the quotes) is short for "rwed".  A "/" indicates that
$! the class is to have to privileges.  A carriage return with no code
$! indicates that that class should be left unchanged.
