Components of a structure are referenced using the percent sign `%' operator. For example, latitude in the structure my_coordinates, above, is referenced as my_coordinates%latitude. latitude in type coordinates in structure my_town is referenced as my_town%coordinates%latitude. If the variable is an array of structures, as in cities, above, array sections can be referenced, such as
which references the component name for all elements of cities, and
which references element latitude of type coordinates for elements (1,1) and (1,2) only of cities. Note that in the first example, the syntax
is equivalent and is an array section.
