the out of the box reporting does not have , to my knowledge, a feature to only report the coordinates for multiple points in one go.
Ie, you can select multiple points and then go Information - Object and see the coordinates, but you will also get other data reported such as type of object , layer, color, name etc.
Or, you can go Information - Point and get the report you ask for , but you cannot select more than one point at a time...
I think you would need a custom journal to create this report.
Creating the points :
Menu - Insert Datum / point - Point set... Curve Points , Curve points by = Incremental arc length, select the curve, enter the distance. OK.
