Delete (Reserved word) In french: Libérer
The memory occupied by a dynamic object (array, class object, ...) is automatically freed when the object is no longer used or when closing the element (window, report, ...) in which the dynamic object was declared. Delete is used to explicitly free the memory occupied by: The use of Delete is optional. Delete allows the developer to quickly free the available memory space. CustomerArray is dynamic array

For more details, see Dynamic arrays.
Special case: the dynamic automation objects The dynamic automation object is automatically freed at the end of the process containing its declaration or during a new allocation of the object. Special case: the class objects and the dynamic class objects To free an object, you also have the ability to use the following syntax: You can also: - Free the memory space used by a matrix with MatDelete.
