Darrel,

Perfect!

I was just in the process of writing my own routines to do the same thing.
I was comparing element 1 in an array with every element in the second array, then element 2 in the first array against every element in the second. If I found a match, I would increment the pointers to both arrays and compare again.
What a mess that was!

Of course, your routine is better/faster/smaller.

Thanks!
