Structures

Structures are the single elements of a structure and so simply are datatypes. On creating a structure element always an existing data type has to be selected. Structure elements can be embedded or linked.

Embedded structure elements	can have properties different from their basic datatypes. The properties are defined individually for each structure element and are saved there.
Linked structure elements	get their properties from the basic datatypes, they are linked to. If the basic data type is changed, all linked elements are changed in the same way!
