        Ever wanted to remap the keyboard? To customize it to your liking?
perhaps even convert it to a Dvorak keyboard for speed? Here's your chance.
ANSI codes can be used to tell BIOS how to handle keystrokes. The example 
below changes the keyboard so that when ever [spacebar] is pressed;

- Not actually give a space
- Do a dir command
- Do a version command
- Print "Hello" on the screen

                ESC[32;27;"dir";13;"ver";13;"rem Hello!";13p
        
        In a real ANSI program, the ESC would be replaced with the ASCII 
symbol for escape. All ANSI codes MUST include ESC (ASCII symbol) and "p" at 
the end. A breakdown of the above code is as follows.

                ESC[32;27;"dir";13;"ver";13;"rem Hello!";13pÄÄÄ The end
                 ³   ³  ³   ³   ³   ³    ³    ³
             Start   ³  ³   ³   ³   ³    ³    Prints hello
                     ³  ³   ³   ³   ³    all dos...
                     ³  ³   ³   ³   Version command
                     ³  ³   ³   Must be put in fron of all dos commands
                     ³  ³   The dir command
                     ³  Cancels the space
                   Shows what key to remap


        Here is a list of keystrokes and their ANSI equivalent.

Code(s) Meaning
_______ ______________________________________________
15      Shift-Tab
16-25   Alt- Q,W,E,R,T,Y,U,I,O,P
30-38   Alt- Z,X,C,V,B,N,M
59-68   F1-F10
71      Home
73      PgUp
79      End
81      PgDn
82      Ins
83      Del
84-93   F11-F20  (Shift-  F1-F10)
94-103  F21-F30  (Ctrl-   F1-F10)

        Unfortunately, such ANSI programs can be damaging. It is quite easy
to take this knowledge and write malicious programs that damage programs. To
protect against such a threat take these simple precautions.

- NEVER under any circumstances use type command. This will execute the code!

- NEVER use pegasus mail if you are expecting attachments. It will execute 
  all code, malicious or not, and theirs nothing you can do about it because
  it's external viewer cannot be turned off.
