I have a feeling this is probably going to get a lot of responses related to the most efficient way to do this! I have no idea how efficient this would be but I'll start the ball rolling with this code.
repeat with x=1 to the number of lines in tlist1 if line x of tlist1 is not among the lines of tlist 2 then < you found a unique tlist1 value > end if end repeat repeat with x=1 to the number of lines in tlist2 if line x of tlist2 is not among the lines of tlist1 then < you found a unique tlist2 value > end if end repeat Another thought I had involves using an array as follows: repeat with x=1 to the number of lines in tlist1 add 1 to array[line x of tlist1] end repeat repeat with x=1 to the number of lines in tlist2 add 1 to array[line x of tlist2] end repeat repeat for each key myKey in array if array[myKey]=1 then < you found a unique value > end if end repeat Depending on how many entries you expect in each list and how long each entry is, the array solution could chew up a huge amount of memory. These are both pretty simplistic solutions which probably means they wouldn't be the fastest. I have no idea how fast either of them might be and I know there are definitely some efficiencies to be had by using either repeat with vs repeat for but I can't remember which is the faster.
