Specifies that the field contains the address  of  another  field  or
 record  definition.  In PL/I, for example, POINTER fields are used to
 access based variables and buffers allocated by the system.  Although
 PL/I  does  not  associate  POINTER  fields  with  a specified record
 structure, other languages do; the optional [TO path-name]  lets  you
 connect a POINTER to a structure.
