How to halt a script halfway & wait for a user entered CR?

Thanks ...that's useful info.

Actually by rethiinking my approach I can avoid having to go with such a routine (or using the rotation wizard)

Mount the pcb chip breaker cutter (1.6mm dia)

Loosely clamp the pcb down

Make sure my first registration mark is 0,0

Align the webcam over the registration mark. (ie @ 0,0 as mentioned by gerry earlier)

Have the CNC drill the pcb hole and dowel pin hole all at once (I used to have to do this manually in two stages 1. with a drill press and the pcb .2. On the CNC machine for the dowel pin)

Pop a 1.6mm dowel pin through the pcb into the hole in the spoil material below

Now shuttle the webcam over to known cordinates (ie where my 2nd regsitartion mark is) ... physically move the pcb until it is aligned (it will pivot/rotate around the 0,0 pin/hole which I drilled earlier)...once aligned on camera, clamp the pcb down firmly.

Job is ready to run - this is sort of a halfway solution between what I was wanting to do, and what I'm doing now, but I think it might work out best in reality ( reckon about 1 minute to align)
