Reinitializes the elements of fixed-size arrays and deallocates dynamic-array storage space.
The array argument is the name of the array variable to be erased.
It is important to know whether an array is fixed-size (ordinary) or dynamic because Erase behaves differently depending on the type of array. Erase recovers no memory for fixed-size arrays. Erase sets the elements of a fixed array as follows:
|Type of array||Effect of Erase on fixed-array elements|
|Fixed numeric array||Sets each element to zero.|
|Fixed string array||Sets each element to zero-length ("").|
|Array of objects||Sets each element to the special value Nothing.|
Erase frees the memory used by dynamic arrays. Before your program can refer to the dynamic array again, it must redeclare the array variable's dimensions using a ReDim statement.
The following example illustrates the use of the Erase statement.
Dim NumArray(9) Dim DynamicArray() ReDim DynamicArray(9) ' Allocate storage space.
EraseNumArray ' Each element is reinitialized.
EraseDynamicArray ' Free memory used by array.
