I need to extract the beginning/ending coordinates of every shape within a polyline shape file. It would be best to actually add them as values within the shape files .dbf (I can live without doing this).

What is the easiest way to do this in ArcMap? I know that XTools has a plugin that does this really easy, but I don't want to purchase software for something that seems like it should be fairly trivial.

Thank you!

**Edit**

I am currently using ArcMap 10.
