Thanks Jim.
I included your suggestion on the script and run fine.
But how can I skip (record X and Y as NULL) on some steps?
On this example it don´t occour, but when working with real data I will need
bypass some acquisitions. Is there a way of do it on a for() looping? I
noticed that if I click on right button of mouse the locator() ask for
continue or stop. But some times I just want to record NULL for the
position.
Thanks a lot,
Miltinho
