Example
MyArray is array of 2 strings
MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete all the elements
MyArray.DeleteAll()
 
Syntax
<WLanguage variable>.DeleteAll()
<WLanguage variable>: Array, queue, stack or 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
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-allocating the array.
  • Two-dimensional array: only the array rows are deleted. The columns are kept. Therefore, <Array variable>.AddLine 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.
Note: To reset the array elements to 0 or to "" without resizing the array, use VariableReset.

Miscellaneous

This function cannot be used with the fixed arrays.
