I have a LISP routine which measures between two points using getpoint, it then creates a table and (will, once I've finished) populate the table with figures, based on the measured value.
The problem is when I select the first point, there is no visual feedback of where I selected, such as there is when using the built in distance tool. For example, in both of the below screenshots, I have chosen my first point to measure from, but not the second where I want to measure to;
Using the distance tool;

Using my tool;

How, in LISP, can I add this "dynamic input" (I think thats the correct term?) to give my user some kind of visual feedback that the tool is working as they expect?
Thanks
