Hi Kem,

I think this is false report.
We have all you need.

In the examples I was able do everything I was need.

ANSWER: 

    you can convert bitset into ArraySet using constructor
    of class ArraySet

            ArraySet( inBitSet as VBiteSet )

Exmaple

    dim bs as VBitSet
    dim as as VArraySet

        bs = fld.find( something )

        as = new VarraySet( bs )
