Reinitializes the elements of a fixed-size array and frees up storage space for the dynamic array.

Erase array

The array parameter is the name of the array variable to clear.

Description

It is important to determine whether an array is a fixed-length array (regular) or a dynamic array because Erase operates differently depending on the type of array. Erase does not need to restore memory for fixed-size arrays. Erase sets the elements of a fixed array according to the following table:

The influence of array type Erase on fixed array elements fixed numeric array sets each element to 0. The fixed string array sets each element to a zero-length string ("). The object array sets each element to a special value of Nothing.

Erase frees the memory used by dynamic arrays. Before the program references the dynamic array again, the dimension of the array variable must be redefined using the ReDim statement.

The following example shows how to use an Erase statement.

Dim NumArray (9) Dim DynamicArray () ReDim DynamicArray (9) 'allocates storage space. Erase NumArray 'every element is reinitialized. Erase DynamicArray 'frees up the memory occupied by the array.
