Basic question about Calculate Geometry

I am a new user of ArcGIS and have the 9.3 version. I have 2 features sets with projected coordinates. Both sets have the same projection. The first set wasn't well positioned (because of an imprecision in my first GPS measurements) so I had to move the first set toward the second one to stak some reference feature together (with Spatial Adjustment).

I created 2 new fields (new X and new Y) and used "Calculate Geometry" to get , I strongly suppose, the new X and Y coordinates of moved features. Here is my question:

If I use my first features set in a new map, will ArcGIS use the new coordinates? Or will it use the oldest? Do I have to save somewhere the new coordinates, even if they have been calculated in the new fields I created in the Attribute table?

The new location is stored in the shapefile itself and there is no need to recalculate the coordinates.

If you were to look at the coordinates of each vertex you would find that they have automatically changed to reflect the new spatial position.

Unless you need the Coordinate fields you calculated for some other purpose, they are unnecessary.

All right, thank you very much!

Have a nice day!
