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,
