DOMAINSFILE domains.tabIf you haven't got a domains file, you can download one from http://www.statslab.cam.ac.uk/~sret1/analog/domains.tab. It should contain each domain code followed by its location on a new line, thus:
ad Andorra ae United Arab Emirates [...]It does not need to be in alphabetical order, though humans may prefer it that way.
Only domains which occur in the domains file will get their own line in the Domain Report: the rest are probably spurious, and will be accumulated together as "unknown domains". If you have debugging turned on, you can see which domains were unknown.
