Merge Paradox databases

Problem

I've got 3 databases of an application called `Astroscoop Plus', how do I merge them into 1?

The database format appears to be Paradox. Using these shareware utilities, I'm able to dump and manually merge the databases:

Paradox Viewer – http://www.scalabium.com/pdx/ (view & generate SQL)
GiPo@DB_Explorer – http://www.gibinsoft.net/gipoutils/dbutil/rightview.htm (insert SQL)
TUTI - Table utilities – http://www.tutisoft.com/ (reindex & pack)
