Thanks everyone - Parloc was the program, have found it, downloaded and got it working. I had a disasterous system crash over the Christmas, and lost almost all my files - the exceptions being those that were backed up to excel. . but I also lost 2 lots of census data, so I am now trying to put everything back in order. I usually keep my backups on an external drive, but the crash occurred while I was backing up and caused problems with my hard drive and my external drive. I suppose this is as good a time as any to re-evaluate my data. Thanks again Caryl
