That's exactly what I wanted. Thank you. I didn't realise that
sending an interrupt signal was treated as a "normal" error.
Out of interest, is there any way to resume the routine from where it
was interrupted (and ideally do so in debugger mode, so I can step
through the lines of the code)?
Thanks again
