Say what!?

What do you think this code does, exactly? It looks to me
like it creates a 1000 by 101 array filled with integer
zeros. It would be easier to do this:

array = IntArr(1000, 101)

But this seems so obvious, that I think I am missing
the intent of the question. Could you please elaborate
some more?

Cheers,

David
