Geoff is right, I was very naughty to use NULL when it is not an
unknown amount. I promise my real databases do not interchange null
and 0 or null and '' !!

I had thought of some alternatives but License_Restrictions and
Administrations = 0 is a bit misleading.

I also did think of the IN ....., but as someone else pointed out, any
of them being true would make the whole lot true.

Maybe a line like

and AvailableOSCount > 10
and FreeForCommercialUse = 'T'

and I could keep going ....

and footprint < 5MB
