Looking at Cohen's "Ada as a 2nd Language" I see in chapter 8 (Access
Types), p.319, this construct which I do not understand.  But first,
the construct I do understand:

  Old_Serial_Number := Serial_Number("Lovelace, Ada").all;

No confusion about that whatsoever.  However, that is followed by
this:

  "More interestingly, the assignment
      Serial_Number( "Lovelace, Ada").all := New_Serial_Number;
  copies the contenst of the integer variable into the variable
pointed to by the result of the function call."

Huh?  Where does the New_Serial_Number value end up here?
