Abstract: A method, system and program product for updating a list. A first list associated with a first platform includes a first plurality of data entries which includes a first plurality and a second plurality of keys. A second list associated with a second platform includes a second plurality of data entries which includes a third plurality of keys, and which match the first plurality of data entries. The first plurality of keys is formed from a character set that includes a subset of characters that are sorted differently on the first and second platforms. The second plurality and third plurality of keys are formed from characters sorted identically on said first and second platforms. After the first list is updated, the lists are sorted and compared. The second list is updated, thereby providing a match between the first plurality and second plurality of data entries.
