in reply to Removing duplicates lines

Could you try explaining your question again? if you just want to skip consecutive lines with identical 10th/11th digits, it's quite straightforward.

Must each code be unique across all 8 files?

Thanks.

    No the code won't be unique across all 8 files. If the code repeats, it will be in the next line or line after that in that same file. I am just trying to do the easy part here (skipping to the next line if this code is repeated).. just can't get around to it.
    Thanks
