Description
If elem is an element of the array type, returns a new array that includes the specified element at the end.
Parameters
Return Type
Array
Examples
Example 1
watchers2 = addElement(watchers, currentUser());
The result returned by the routine is assigned to a new array watchers2, so the initial array watchers will not be modified.
Example 2
watchers = addElement(watchers, currentUser());
The result returned by the routine is assigned to the same array watchers, so the initial array watchers will be modified.
If elem is not the same type as declared in the array definition, the routine returns error.
Starting with version 2.5 is easier for you to just use the '+' operator to add elements to an array. array = array + element it is a simple and more meaningful way to express it. array += element is even better.
