1. I know that there is no bit addressing
2. Both calls are identical in my example ( sizeof(TDigits) IS EQUAL TO 2 ).
    You need at least 2 bytes to store 10 "boolean" values.
3. My point was: Does the function need the number of bits to check (10)
    within the bytes received (2) or the number of bytes (2) used to stored
the set?
4. I hope this will be a built-in function in future version of Delphi.
5. Thanks for the solution
