MyArray[1] = "WINDEV"
MyArray[2] = "WEBDEV"
// Delete the 1st element
Delete(MyArray, 1) // Deletes "WINDEV"
// Display the 1st element
Trace(MyArray[1])  // Displays "WEBDEV"
// Associative array Last Name - First Name
aaLastNameFirstName is associative array of strings
Insert(aaLastNameFirstName, "Smith", "Tommy")
Insert(aaLastNameFirstName, "Montgomery", "Julia")
Delete(aaLastNameFirstName, "Smith")

Syntax

Deleting an element from a WLanguage array or from an advanced array property Hide the details

<Result> = Delete(<WLanguage array> , <Element subscript>)
<Result>: Integer
Number of deleted elements (always corresponds to 1).
<WLanguage array>: Array
Name of Array variable to use. This array must be a one-dimensional array.
<Element subscript>: Integer
  • Subscript of element to delete. A WLanguage error occurs if this parameter is greater than the number of array elements.
  • Versions 17 and later
    The following constants can be used:
    FirstElementThe first array element is deleted.
    CurrentElementThe current element is deleted. This constant is used to delete the current element during a FOR EACH browse.
    This constant is only available for associative arrays.
    New in version 17
    The following constants can be used:
    FirstElementThe first array element is deleted.
    CurrentElementThe current element is deleted. This constant is used to delete the current element during a FOR EACH browse.
    This constant is only available for associative arrays.
    The following constants can be used:
    FirstElementThe first array element is deleted.
    CurrentElementThe current element is deleted. This constant is used to delete the current element during a FOR EACH browse.
    This constant is only available for associative arrays.

Deleting an element from an associative array Hide the details

<Result> = Delete(<WLanguage array> , <Element key>)
<Result>: Integer
Number of deleted elements:
  • 1 or 0 for the associative arrays without duplicates.
  • 0 to N for the associative arrays with duplicates.
<WLanguage array>: Associative array
Name of Associative Array variable to use.
<Element key>: Integer
  • Value of key corresponding to the element to delete.
    • In an associative array without duplicate: If the element exists, it is deleted ; if the element does not exist, no operation is performed.
    • In an associative array with duplicates: If the element exists, all the <Element Key> elements are deleted ; if the element does not exist, no operation is performed.
  • This parameter can also correspond to the CurrentElement constant. This syntax is used to delete the current element during a FOR EACH browse.
Remarks

Deleting the last element

If the last element is deleted, the array is resized to 0. The array has not been deleted: new additions can be performed without re-creating the array.

Miscellaneous

This function cannot be used with the fixed arrays.
