Actually, that's the way Fortran sees the array, too.
The array is a "first class object", just as much a single
entity as any other.  Programming for high performance
has taught me to look at things at two levels simultaneously:
what the langauge says and means, and what's going on in
the hardware.  Of course, on scalar processors, things actually
happen element by element.

<snip further discussion and sig>

I like the built-in tasking in Ada, Fortran uses add-on libraries
to achieve the same thing.  Often vendor specific, and therefore
something of a nuiscance.

BTW, I found Barnes' Ada95 book at www.bookpool.com at a substantial
discount.  They're out of stock :-(, but I backordered.

That's 2 I owe this group.
