A simple example we all know...
I live in an array called a "house"
It contains rooms thus

house[kitchen]

Wait, wait,not so fast. I get that arrays are hierarchical. But I
need to know what you mean by the line above.
RR won't compile [top shelf], is "shelf" a parameter associated with
"top"? Or was it an abbreviation for top_shelf or maybe topShelf?
And what happens to the trailing "cheese,pickles, butter"? is this
now the array element assigned to house[kitchen][refrigerator][top
shelf]
As you see, I can't get started with this until I get a handle on the
notation.
You are correct that Rev won't compile
house[kitchen][refrigerator][top shelf]
but it will compile using the syntax
house["kitchen"]["refrigerator"]["top shelf"]
I left out the quotes so it would read better.
So the syntax would be
put "cheese, pickles, butter" into house["kitchen"]["refrigerator"]
["top shelf"]
Hope this helps,

Thanks Jim. I get it.
I do a lot of election database work for local political candidates
at election time.
In that case there are a fixed set of defined fields for each voter
record.
I use RR a lot for constructing mailing labels for select political
mailers, i.e. mail to households, or to families using first names,
or just to individuals.
It doesn't appear that the hierarchical nature of RR multi-
dimensional arrays would be an advantage in these kinds of applications.
Thanks again,
Jim Hurley
