- LOCK utility V1.0 (c) 23-Nov-1989
- The LOCK program for a DOS version 2 and up locks the
- MS-DOS / PC-DOS system from further use until the correct
- password is entered. It seems ludicrous to lock a MS-DOS
- system when a reboot, or another system diskette could
- allow entry. But allot of systems are now on some sort
- of network and the network session connection's needs to
- be protected.

- The syntax of the command is:
-
- LOCK
-
- Then the program will prompt for the lock password, it's
- verification and then the ultimate prompt for the unlock
- password. Example:
-
- lock
-
- Lock password>
- Verification>
-
- Unlock password>
-
- If LOCK has any arguments a help message is issued.
-
- Note: The maximum password is eigthy characters, with
- all lower case converted to upper case. It's hard enough
- to remember a password let alone a what case to use on a
- temporary password. All spaces and tabs are eliminated,
- so phrases can be used more easily.

-
- LOCK terminates with int 21h, AH=4ch, the intention is
- that the program can be called from another program, but
- I guess that will have to wait for version 2.
-
- LOCK returns errorlevel codes, which are:
-
- command, help issued 00h
- don't know about MS-DOS version 1.x 01h
- normal end of program 02h
