Final answer:
To maintain control in a file area after a record removal, it is necessary to insert an element that ensures structural integrity, such as a pointer or another kind of control mechanism.
Step-by-step explanation:
To maintain control of the file area, an anchor must be inserted each time a record is removed from the area.
When a record is deleted from a file area, especially in a database or a data structure such as a linked list, it's necessary to ensure the integrity of the structure by inserting an appropriate control element. In databases, this can be a pointer update to ensure the remaining records are properly connected. In the context of file systems, an analogous control action must be taken to maintain the organization and integrity of the file area.
This is crucial for orderly record management and avoiding data corruption or loss. Understanding and implementing these control measures is vital for anyone studying databases or file system organization at the college level.
