=======

This article describes how to create MS-DOS-based programs to toggle the CAPS
LOCK and NUM LOCK keys on and off.

MORE INFORMATION
================

To Toggle the CAPS LOCK Key On
------------------------------

1. Use any text editor (such as Notepad) to create the following file:

      a 100
      mov ax,0040
      mov ds,ax
      or byte ptr [0017],40
      mov ah,1
      int 16
      mov ax,4c00
      int 21

      r cx
      0013
      n CAPS_ON.COM
      w
      q

2. Save the file as Capson.deb

3. Type the following line at a command prompt:

   " debug < capson.deb " (without the quotation marks)

   This creates an MS-DOS-based program named Caps_on.com that toggles the CAPS
   LOCK key on.

To Toggle the CAPS LOCK Key Off
-------------------------------

1. Use any text editor (such as Notepad) to create the following file:

      a 100
      mov ax,0040
      mov ds,ax
      and byte ptr [0017],bf
      mov ah,1

      int 16
      mov ax,4c00
      int 21

      r cx
      0013
      n CAPS_OFF.COM
      w
      q

2. Save the file as Capsoff.deb

3. Type the following line at a command prompt:

   " debug < capsoff.deb " (without the quotation marks)

   This creates an MS-DOS-based program named Caps_off.com that toggles the CAPS
   LOCK key off.

To Toggle the NUM LOCK Key On
-----------------------------

1. Use any text editor (such as Notepad) to create the following file:

      a 100
      mov ax,0040
      mov ds,ax
      or byte ptr [0017],20
      mov ah,1

      int 16
      mov ax,4c00
      int 21

      r cx
      0013
      n NUM_ON.COM
      w
      q

2. Save the file as Numon.deb

3. Type the following line at a command prompt:

   " debug < numon.deb " (without the quotation marks)

   This creates an MS-DOS-based program named Num_on.com that toggles the NUM
   LOCK key on.

To Toggle the NUM LOCK Key Off
------------------------------

1. Use any text editor (such as Notepad) to create the following file:

      a 100
      mov ax,0040
      mov ds,ax
      and byte ptr [0017],df
      mov ah,1

      int 16
      mov ax,4c00
      int 21

      r cx
      0013
      n NUM_OFF.COM
      w
      q

2. Save the file as Numoff.deb

3. Type the following line at a command prompt:

   " debug < numoff.deb " (without the quotation marks)

   This creates an MS-DOS-based program named Num_off.com that toggles the NUM
   LOCK key off.

Using the Toggle Programs
-------------------------

Place the appropriate command in the Autoexec.bat or Config.sys file to
automatically toggle the keys you want. For example, adding

   NUMLOCK=OFF

   -or-

   NUMLOCK=ON

to the Config.sys file will turn off or turn on the NUM LOCK key.

NOTE: You must be using MS-DOS version 6.x or later. This function was retained
in Windows 95.
