Consider pumping it into a text format and using UltraCompare (UltraEdit companion product).

Hi, I am looking for a more robust file compare routine than proc compare. What I would like is a sas technique that works like the unix DIFF command. I have two SAS ds, where each row may match or it may have extra rows on either ds. There is no common key or sort order.


ds1 ds2

x x

1 1 2 3 3 4 5 5 5 4

What i would like would be something like.

x x_1

1 1 2 . 3 3 . 4 5 5 . 5 . 4

Proc compare doesnt seem to handle extra rows in either of the two files unless there is a key (id). There is some written about the diff algorithm, but they are mostly written in c or such, and Im a SAS guy. Does anyone have an algorithm that can do this and be adapted to SAS?
