Erase - statement of language VBScript

Description:
Reinitializes items of fixed-size array and deallocates dynamic-array storage space.
Syntax:

Erase array
The array parameter is the name of the array variable to be erased.
Note:
It is important to know whether an array is fixed-size (ordinary) or dynamic because statement behaves differently depending on the type of array. Erase recovers no memory for fixed-size arrays. Erase sets items of a fixed array as follows:

Type of array Effect of Erase on fixed-array elements
Fixed numeric array Sets each item to zero.
Fixed string array Sets each item to empty string ("").
objects Sets each item to the Nothing value

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.
