I do not agree with this. When there is no data, there is no data, neither true nor false. And the null flavour gives us the reason for that case. I think the DV_BOOLEAN is perfect as it is and if in some case it is not good for your needs, then you should use a different data type (a coded text for example). -- David Moner Cano Grupo de Inform?tica Biom?dica - IBIME Instituto ITACA http://www.ibime.upv.es Universidad Polit?cnica de Valencia (UPV) Camino de Vera, s/n, Edificio G-8, Acceso B, 3? planta Valencia ? 46022 (Espa?a) -------------- next part -------------- An HTML attachment was scrubbed...
