Thanks merlyn, but I'm a little embarrassed. I just got P.O.R.&M (the Alpaca book) and was only on Chap 3. Autovivification is in Chap 4 {grin}.

Anyway for anyone actually following this thread $data[0] and $data[1]need to be switched in meryln's clever one-liner.

I tried the code and it worked first time, but it does not delete duplicate cities, only duplicate states. So, in my example, 'Dallas' would show up 5 times under 'Texas'.

Well, on to Chap 4 of the Alpaca book to see how this can be remedied.
