I have used your code to add a function bit-vector-count that count the number of set bits in the bit-vector. There is an issue of potential confusion over names though. In the data collection, the -count suffix normally returns the size of the data structure. For vectors the suffix -length is normally used. -- Jens Axel Søgaard _________________________ Racket Developers list: http://lists.racket-lang.org/dev
