So far it seems to me, that Nulls can be created only MANUALLY.
Like
dim var as variant
var = Null
And you can check this with isNull.
But you can never ever produce a Null value in any of the calculations, no matter what you do. Am I right in this? You can only use it if u create it MANUALLY.
So I don't understand why its useful. I could use instead of null any string for marking a variant, like "Sunshine".
If variant is Sunshine, I do something.
So what is the use of Null? I feel completely confused, sorry
