Simply pick a point on the screen. Pick a second point for the text and a Mleader will be created for you pointing to the first point picked.
The text of the Mleader will hold the X and Y values of the first point picked.
The LISP routine is open source so you can edit it as you see fit.
For instance you might want to change the precision of the X and Y values or maybe change the X and Y to Northing and Easting, etc.
Added support to AutoCAD® 2022 (No change in version number).
