the file must be loaded and, in addition, must be tested using data to add records and delete and change the records within the file. When a direct file is used, the algorithm used to determine record addresses must be tested and also the routine which handles synonyms must be heavily tested. Any time data is stored on a file, such as disk, CD, or cartridge, whether it is relational, sequential, indexed sequential, or direct, the data should be dumped by using a utility program so that the file
