No. It just gets a pointer to the array variable first,
rather than trying to do it in one step. The problem
seems to be that the array is not part of a dic object
model, so you can't reference it that way.

It will probably slow things down. If you're doing something
big I wonder if a dictionary class could be better. I use them in
VB6. But everything's slow in VBS due to the constant data
I do a similar thing to unpack MSI files and it works reasonably
well. I process all the data into an object model by using numerous
dictionaries to store it.
I assume you know you can access the items as a Keys array.
But of course that, not typically useful unless you just want to
walk the array. It defeats the purpose of accessing one item directly
by its keyy name.

Sounds right. In other words, there's no object model.
With something like DOM you can have document.DivA(3).borderstyle,
but that's because the whole thing is an object model. The
variable pointer here is to the dictionary. Dictionary members
are not variables until you reference them. I hadn't thought of
it that way, but it makes sense.
