Hi all, 
 
I ask: "why not to disallow nulls in boolean fields?". It was a question not a proposal.
The explanation was clear to me. Nulls are not values but the absence of a known value.
 
It is comparable to the state of a c (or almost any other programming language) variable that had not been initialized. It is not a matter to disallw it, because is implicit in the nature of the programming languages. Am i right?
 
(Maybe my english is not perfect, is not my mother tongue but a lerned one.)
 
 
Thanx in advance,
Jaime Casanova

Umm - what proposal?

Umm - who is suggesting prohibiting nulls? I've re-read the entire 
thread and can't find any such suggestion. Is this one of those 
occasions where the different dialects of English are causing confusion?
