Syntax

<WLanguage variable>.DeleteAll()

<WLanguage variable>: Array, cola, pila o List

Name of the WLanguage variable to use. This variable can be:
an array. This array must be a one-dimensional array or a two-dimensional array.
a queue.
a stack.
a list
Only Array variables can be used.

Remarks

Deleting Items

One-dimensional array: the array is resized to 0. The array has not been deleted: new additions can be performed without re-creating the array.
Two-dimensional array: only the array rows are deleted. The columns are kept. Therefore, TableauAjouteLigne_objet can be used after <Array variable>.DeleteAll.
Associative array: all array elements are deleted.
Queue: all queue elements are deleted.
Stack: all stack elements are deleted.
List: all list elements are deleted.

Remark: To reset the array elements to 0 or to "" without resizing the array, use VariableReset.

The deletion of elements is not available for the Queue, Stack and List variables.
