>> An area is a region in which space for based variables
can be allocated. Areas can be cleared of their allocations
in a single operation, thus allowing for wholesale freeing.
Moreover, areas can be moved from one place to another by
means of assignment to area variables, or through input-output
operations.
>> Based variables are useful in creating linked data struc
tures, and also have applications in record inputoutput. A
based variable does not have any storage of its own; instead,
the declaration acts as a template and describes a generation
of storage.
