Dear Svend,
Thank you for your kind help. For maxage and bromaxage, my main
motivation was to take into account twin, triple kids. But,
unfortunately, I can't use then efficiently in the first place to
derive the number of older boys.
If I turn back to your code, could you give me any advice how I can
take into acoount twin, triple kids?
Thank you very much in advance.
