Retrieve all of the records of the file logically sequentially based on the Sailor Name field. iii. Retrieve all of the records of the file logi- cally sequentially based on the Sailor Number field. iv. Retrieve all of the records of the file logi- cally sequentially based on the Ship Number field. v. Perform a direct retrieval of the records with a Sailor Number field value of 27467. vi. Perform a direct retrieval of the records with a Ship Number field value of 020. vii. Perform a direct retrieval of the records with a Job Title field value of Captain. c.
