Adding and removing elements

You can add elements in an associative array simply by referencing new subscripts. To add elements to nested tables or VARRAYs, you must first enlarge the collection with the EXTEND function and then assign a value to a new element using one of the methods described earlier.

Use the DELETE function to remove an element in a nested table regardless of its position. You can also use the TRIM function to remove elements, but only from the end of a collection. To avoid unexpected results, do not use both DELETE and TRIM on the same collection.
