ah yes, that took down some of the complexity of the code quite a bit, and I will post the revision tommorow once I am in work again. Another thing I noticed is the fact that each time it finds a MATCH INTERFACE type, it goes and gets a relist of all of that type of card, which extends the overhead of the program with time and processing. I think the $knownthing was supposed to be part of that future logic, but it didnt get into a final revision =\ Thanks for your input it was greatly needed!
