I need to look at an Array A and see if any one element is also in Array B.
I'm going to loop through Array A and lookup in B.
Just wondered if there was a quicker way, like using SETLL instead of READ

If you use the Ascend keyword on the array and sort it prior to doing a %Lookup you will get a binary lookup which is as fast as you are going to get.

And just FYI SETLL is not always faster than CHAIN (which I assume is what you meant) - see the archives for the full gory story ...
