In most instances, an internal data structure known as the data set is associated with the table field. The data set is linked to the table field when the table field is initialized. The data set stores all rows associated with the table field, whether or not the rows are displayed. Because the FRS manages the data set, a program need not be concerned with where data is coming from or going to during a scroll. The program can load many rows at once into the table field, even though the rows cannot be currently displayed. The program need not save deleted rows for later data manipulation because, although deleted rows disappear from the table field display, they still exist in the data set and can be used later for such tasks as updating the database.
