    I had the bright idea of including an integer field in each record of a
    table which would be descriptive of the person in the table e.g 1 st bit
    set might indicate sex, 2nd bit hair color and so on so an entry with
    10010011 might indicate a male with green eyes. I then tried to set a filter
    in the table such as 'mask and 3 = 3' to find all males with green eyes.

    Sounds OK in theory but I just get a 'type mismatch in filter condition'
    error when I try it.
    I have tried the obvious fixes such as table.filter := 'mask and
    '+intTostr(3) + ' = ' + intTostr(3)

    Any ideas ?
    Cheers
