Ordering an associative array - or - another option

[Paul]

I have and array string[string][string][string] that works great 
for everything I need except that they (assoc. arrays) don't 
maintain an order.  I need to maintain the order of entry.

Are there any work arounds that others have used?  I saw some 
tricks in the book for sorting a single dimensional assoc. array.

Thanks to all!
