Constraining Array.sum( ) for One/Two Dimesional Unpacked Array

In reply to javatea:

Hi ,

If you would have read my question properly u would know that I did go through the LRM 18.5.12 ( Have even mentioned a quote above ) . But unfortunately I still am missing out on something.

If you know where do I go wrong , I would have preferred that over your 3 lines ( 2 to be precise since the 2nd line doesn’t make sense ) that I already know .
