The data type of a variable also determines which built-in routines you can use with the variable
(see Chapter 15 (page 274)).
Address Types
Every identifier that you declare has both a data type and an address type. The data type describes
the data item itself. The address type describes the address of the data item. If you declare a pointer
to the data item, the value that you assign to the pointer must be of that address type.
You cannot explicitly declare the address type of a pointer. When you declare a pointer, the
compiler determines its address type.
