mileage between 2 specific points

[MelissaMann]

Hi, I need to calculate the distance between 2 sets of points (over million routes to calculate). In the past I've found the shortest distance, but I'm not trying to find the shortest distance, just calculate the mileage between these sets of points. They are in different layers, how do I configure the parameters? Find Route?? I have a key that match the points.

Thanks!

This has been answered many times before in the forums. Basically search the forums for the ROUTENAME keyword.
For example this post has more info on how to do it:

You may want to run gp tool "calculate locations" on your points once and then use these location fields to load them into the route layer in case you have to do this more than once.
