1 This document revises the version dated 28 May 1996  by  incorporating
  the  substantive  changes approved by ISO WG21 and ANSI X3J16 at their
  joint meeting in Stockholm, Sweden in July, 1996.   It  will  be  pre­
  sented  for  approval at the joint meeting in Hawaii, USA in November,
  1996.

2 The C++ programming language as described in  this  Working  Paper  is
  based  on the language as described in Chapter R (Reference Manual) of
  Stroustrup: The C++ Programming Language (second edition, Addison-Wes­
  ley  Publishing  Company,  ISBN 0-201-53992-6, copyright © 1991 AT&T).
  That, in turn, is based on the C programming language as described  in
  Appendix A of Kernighan and Ritchie: The C Programming Language (Pren­
  tice-Hall, 1978, ISBN 0-13-110163-3, copyright © 1978 AT&T).  In addi­
  tion,  portions  of  this  Working  Paper  are  based  on work by P.J.
  Plauger, which was published as The Draft Standard C++ Library;  Pren­
  tice-Hall,  ISBN  0-13-117003-1,  copyright © 1995 P.J. Plauger).  All
  rights in these originals are reserved.

3 The C language changed substantially after The C Programming  Language
  was  published.   Those  changes are reflected in ISO/IEC 9899:1990, C
  Standard which, together with Chapter R of The  C++  Programming  Lan­
  guage, serve as the two base documents for this Working Paper.

4 Most  clause  and subclause titles have text in square brackets at the
  end of their respective lines.  The bracketed text is a symbolic  name
  for  that  clause  or  subclause, with the idea that the symbolic name
  will remain constant even if the corresponding number changes in  sub­
  sequent  drafts.   These symbolic names are there for convenience only
  and are not part of the text; they will not appear in the  final  ver­
  sion of the International Standard.

  Throughout the text appear rectangular boxes, each with a label of the
  form Box n in its upper left corner, where n represents a natural num­
  ber.   These boxes, and their contents, are there for convenience only
  and are not part of the text; they will not appear in the  final  ver­
  sion of the International Standard.

  A  vertical  bar in the right margin shows text that is new or changed
  from the version approved at the Valley  Forge  meeting;  an  asterisk

  there  shows where text was deleted.  These ``change bars'' were mech­
  nically prepared in a way that is sometimes too  conservative:  it  is
  possible  that  text is shown as changed that did not actually change.
  However, the method of preparation is intended to ensure that a change
  bar does indeed indicate every change.
