Example

MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete all the elements
DeleteAll(MyArray)

Syntax

DeleteAll(<WLanguage variable>)

<WLanguage variable>: Array, Queue, Stack or List

Name of variable to use. This variable can be:
an Array. This array must be a one-dimensional array or a two-dimensional array.
a List.
a Stack.
a Queue.
Only Array variables can be used.

Remarks

Deleting elements

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, ArrayAddLine can be used after ArrayDeleteAll.
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 reinitialize (reset to 0 or to empty string "") the array elements without resizing the array, use VariableReset.

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

Miscellaneous

This function cannot be used with the fixed arrays.
