The biggest problem I guess would be getting the data. Any programmer could take the data file and load it into a table like Access. Once the data is loaded you compare the table to itself . read first record on table then scan the same table looking for matches on last and first names. If you get a hit print out the name then go to the next record and repeat until all records read.
