The ADDRESS function returns a pointer value that is the address
  of the parameter.

  Syntax:

     ADDRESS( x )

  The parameter 'x' can  be  a  variable  of  any  type  except  a
  component  of  a packed structured type.  A compile-time warning
  results if 'x' is a formal  VAR  parameter,  a  component  of  a
  formal  VAR  parameter,  or  a  variable  that does not have the
  READONLY or VOLATILE attribute.

  A pointer can only refer to a VOLATILE variable  or  a  variable
  allocated by the NEW procedure.
