SYNOPSIS

LOCK is a program with which you can prevent intruders from using your
computer. You give a secret password to LOCK and it will require that
word typed before it allows any commands.

USAGE

Type LOCK password on DOS command line and LOCK will activate itself and
wait for "password" to be typed. LOCK returns back to DOS only after
correct password. If you do not enter any password on command line, LOCK
will use its own default password (.,mnbvc). It is declared here, so I
advise you to patch a new default password in the program. Use any 7
character code.

Put LOCK in your Autoexec.bat file in the very first line and you'll get
almost complete security against passers-by. According to my tests it is
not very propable that one could terminate Autoexec.bat before the first
line with control-C. But note that this system can be cracked,
if the intruder has his own DOS on diskette. However, LOCK offers you
rather secure way to slow down, at least, novice intruders.
