Dear Don thanks for the reply and the information. However, what I wanted to know (I obviously didn't make myself clear) is how can I change the IRN numbers for the people I have so that they follow a logical sequence? I know how to call them up using the alphabetical list, as you describe; it just doesn't make sense to have parents with IRN numbers of say, 147 and 002, followed by children who are 156, 004, 65 and 12. I'd just like to be able to re-number or re-index them all! Hoping you (or someone out there) can help, but thanks for the thought, Moira
