Sorry for th late reply. Thanks to everybody who responded. 

A little background to the problem - I'm evaluating molecular fingerprints
which use bitsets of length N and set certain bits on depending on whether
a feature is present. So I was essentially looking for Java style bitsets. 

In the end I wrote a small class which did the job (since all I need is to
keep track of which positions are on)

Thanks,
