[fpc-devel] tbits.NotBits

[Andrea Mauri]

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,
Andrea Mauri
