Speaking of Filter and Match...

[Terry Judd]

There are sure to be more elegant ways but you could just rebuild the list skipping the duplicates as you go

# tList1 contains original list
put cr into tList2
repeat for each line x in tList1
    if tList2 contains cr&x&cr then # ensures you check whole not partial lines
        # do nothing
   else
        put x&cr after tList2
    end if
end repeat
put char 2 to -2 of tList2 into tList2 # delete the leading and trailing returns

If you need to retain line specific formatting in the field though you’ll need a different approach.

I have a field with about a thousand lines with many duplicate lines, and I want to delete the duplicates. Seems like this should be simple but I am running around in circles. Can anyone help me with this?

Thanks,
Roger
