ISNULL may be true, whilst NULL != NULL. NULL is not a value.

    Ah, my brain was in C mode, where NULL is functionally 0. This is about the concept, which doesn't apply equally to all languages.

    Yep. There are some languages where this applies, because it’s a mathematical concept. The point is it’s the same ‘no value’ concept, which isn’t shared by implemented the same way by all languages.

    C is strongly typed, and uses pointers, so NULL sort of intrinsically has a value in C.

    edit: my wording was a bit off
