Adding XY coordinates to a polyline

[KarenDouglas]

I have a polyline vector file that has been in our database for a while showing a series of cables on the seafloor. I would like to export this to csv and include xy coordinates in such a way that they could be redrawn in any program. When I use the feature to point function, I get lat and long columns but only for the odd point along the lines and not the start or end. It's possible that some interpolation needs to be done, but I am new to ArcGIS and am not sure how. Any suggestions?

I think you want to use Split Line at Vertices (ArcInfo required). Then, Add XY Coordinates. If you don't have ArcInfo you can use python to cycle through the vertices and write them to a new file (essentially, the opposite of this example).
