Free memory allocated to a system-descriptor area

The DEALLOCATE DESCRIPTOR statement deallocates, or frees, memory that the specified system-descriptor area uses. The freed memory includes memory used by the item descriptors to hold data (in the DATA fields). Make sure that you deallocate a system-descriptor area only after you no longer have need of it. A deallocated system-descriptor area cannot be reused.
