Working with the List Feature

List features can be used to manage list of objects or parameters. These lists can be edited interactively. The List edition window enables the user to sort items automatically and to specify the type of objects authorized.

The list feature is integrated in the update mechanism, the size of the list is computed automatically (it is provided with functions designed to compute sums, areas, costs...).

The list feature can be manipulated through the language to:

	Create list
	Copy the content of a list into another one
	Add and remove elements
	Get an element
	Retrieve values from the list
	Move elements of the list to another position
