Task: List cruises starting in Korfu with their destination and starting date in order of starting date. List the type, name and length of the yachts which sail on these cruises.

Information on cruise starting harbor, starting date and cruise destination is stored in the file SAG-TOURS-E-CRUISE. Information on yacht length, type and name is stored in the file SAG-TOURS-E-YACHT. As each cruise can only have one value for destination, yacht length, name and type, you can take SAG-TOURS-E-CRUISE as the primary file and perform a lookup on the file SAG-TOURS-E-YACHT using the INCLUDE command.

For further information on file lookup, see INCLUDE command and What is File Lookup? in Defining Files in the User's Guide.

Super Natural searches the primary file and lookup file as follows when the transaction is run:

1. A search is made in the SAG-TOURS-E-CRUISE file for all records which meet the selection criterion START-HARBOR = 'KORFU'. The following records are found:

1. For each record found in the primary file, Super Natural searches the lookup file (SAG-TOURS-E-CRUISE) for the first record where the value of the lookup field (ID-YACHT) is the same as that of the link field in the primary file record. The following records are found:

1. The records found in the primary file are returned and the desired information from the corresponding records in the lookup file is displayed.
