CORRECTION: There is a bug(?) in the previous version. Sorry...

Many times, especially when dealing with Windows
API functions, may need to manipulate numbers
in the bit level

This is an example on how to operate on bits 
and manipulate bits. 

It may be useful for the beginner

I included some bit manipulation functions
in BitUnit.pas unit


I use Delphi 4, but you can compile it using
Delphi 3 or 2. Just open the .dpr and ignore any
errors when the form is loaded
