The system is written needing that array, so at some point, I have to put the records into that array (or I can rewrite the system in heaven only knows how many areas). Doing it the way I was doing it only required a few lines of code and everything ended up looking exactly as the original code meant it to. I'm not sure USE AGAIN and SET FILTER is going to buy me anything. Would scanning the filtered table and putting it into the array that way be faster? SET FILTER used to make things really slow, and I've pretty much avoided using it.
