REQHB reads the white page update message texts (ie:MESS.WP). It looks for any question marks in the update lines for US and Canadian calls, if it finds any it then it accesses HamBase and fills in the question mark fields with the needed data from HamBase if any). WPHB will not replace data that already exists in the white pages with that from HamBase, it only replaces the ?'s if possible
