I want to insert a unique html anchor for each sentence, so I need to increment the number to construct a unique name.
What I meant is that it's not a meaningful distinction. Since all variable should be declared, it's like saying "electronic television". Until they use laser circuitry for TVs, there's no such thing as electronic televisions. There are just televisions.
