Your explanations are good. But I must admit that sadly I have never 
mastered pointers, handles, and bit-wise commands. Over the years I 
have studied various BASIC's, Pascal, C, and C++. But I have always 
struggled to have a firm grasp on pointers, handles, and bit-wise 
commands. Each one makes sense to some degree, and I can even explain 
what they are to a large degree, but the real comprehension isn't 
there.

Thanks all,
