one last thing, using TBits it is possible to SetIndex in order to start
from a predefined index when using FindNextBit and FindPrevBit
Anyway it is possible to set the State only using FindFirstBit, so I
cannot use FindNextBit only using SetIndex but I have to call also
FindFirstBit.
Is it possible to introduce a SetState procedure?
Thanks again,

one more thing.
there is a method like clearall to set all bits to 1?
clearall is much more faster then a simple iteration along all bits

I didn't understand how TBits.NotBits works.
Consider the following code:
b:= TBits.Create(NRECORDS);
b.NotBits(b);
or more clear:
b:= TBits.Create(NRECORDS);
b.Clearall;
b.NotBits(b);
I supposed that all bits of b will be 1. What I obtain is that all bits
are 0.

Am I missing something?
Thank you.
