\def\baselinestretch{1}

% Each size-changing command \SIZE executes the command
%        \@setsize\SIZE{BASELINESKIP}\FONTSIZE\@FONTSIZE
% where:
%   BASELINESKIP = Normal value of \baselineskip for that size.  (Actual 
%                  value will be \baselinestretch * BASELINESKIP.)
%
%  \FONTSIZE     = Name of font-size command.  The currently available
%                  (preloaded) font sizes are: \vpt (5pt), \vipt (6pt),
%                  \viipt (etc.), \viiipt, \ixpt, \xpt, \xipt, \xiipt,
%                  \xivpt, \xviipt, \xxpt, \xxvpt.
%  \@FONTSIZE    = The same as the font-size command except with an
%                  '@' in front---e.g., if \FONTSIZE = \xivpt then
%                  \@FONTSIZE = \@xivpt.
%
% For reasons of efficiency that needn't concern the designer,
% the document style defines \@normalsize instead of \normalsize .  This is
% done only for \normalsize, not for any other size-changing commands.

% All margin dimensions measured from a point one inch from top and side
% of page.  

% SIDE MARGINS:
\if@twoside                 % Values for two-sided printing:
   \oddsidemargin  44pt     %   Left margin on odd-numbered pages.
   \evensidemargin 82pt     %   Left margin on even-numbered pages.
   \marginparwidth 107pt    %   Width of marginal notes.
\else                       % Values for one-sided printing:

   \evensidemargin 63pt
   \marginparwidth 90pt 
\fi
\marginparsep 11pt          % Horizontal space between outer margin and 
                            % marginal note


% VERTICAL SPACING:        
                         % Top of page:
\topmargin 27pt          %    Nominal distance from top of page to top of
                         %    box containing running head.
\headheight 12pt         %    Height of box containing running head.
\headsep 25pt            %    Space between running head and text.
% \topskip = 10pt        %    '\baselineskip' for first line of page.
                         % Bottom of page:
\footskip 30pt           %    Distance from baseline of box containing foot 
                         %    to baseline of last line of text.


% DIMENSION OF TEXT:
% 24 Jun 86: changed to explicitly compute \textheight to avoid roundoff.
% The value of the multiplier was calculated as the floor of the
% old \textheight minus \topskip, divided by \baselineskip for \normalsize.
% The old value of \textheight was 528pt.
% \textheight is the height of text (including footnotes and figures, 
% excluding running head and foot).

\textheight = 43\baselineskip
\advance\textheight by \topskip
\textwidth 345pt         % Width of text line.
                         % For two-column mode: 
\columnsep 10pt          %    Space between columns 
\columnseprule 0pt       %    Width of rule between columns.

% A \raggedbottom command causes 'ragged bottom' pages: pages set to
% natural height instead of being stretched to exactly \textheight.

% FOOTNOTES:

\footnotesep 6.65pt   % Height of strut placed at the beginning of every
                      % footnote = height of normal \footnotesize strut,
                      % so no extra space between footnotes.

\skip\footins 9pt plus 4pt minus 2pt  % Space between last line of text and 
                                      % top of first footnote.

% FLOATS: (a float is something like a figure or table)
%
%  FOR FLOATS ON A TEXT PAGE:
%
%    ONE-COLUMN MODE OR SINGLE-COLUMN FLOATS IN TWO-COLUMN MODE:
\floatsep 12pt plus 2pt minus 2pt        % Space between adjacent floats moved
                                         % to top or bottom of text page.
\textfloatsep 20pt plus 2pt minus 4pt    % Space between main text and floats
                                         % at top or bottom of page.
\intextsep 12pt plus 2pt minus 2pt       % Space between in-text figures and 
                                         % text.
\@maxsep 20pt                            % The maximum of \floatsep, 
                                         % \textfloatsep and \intextsep (minus
                                         % the stretch and shrink).
%    TWO-COLUMN FLOATS IN TWO-COLUMN MODE:
\dblfloatsep 12pt plus 2pt minus 2pt     % Same as \floatsep for double-column
                                         % figures in two-column mode.
\dbltextfloatsep 20pt plus 2pt minus 4pt % \textfloatsep for double-column 
                                         % floats.
\@dblmaxsep 20pt                         % The maximum of \dblfloatsep and 
                                         % \dbltexfloatsep.

%  FOR FLOATS ON A SEPARATE FLOAT PAGE OR COLUMN:
%    ONE-COLUMN MODE OR SINGLE-COLUMN FLOATS IN TWO-COLUMN MODE:
\@fptop 0pt plus 1fil    % Stretch at top of float page/column. (Must be    
                         % 0pt plus ...)                                    
\@fpsep 8pt plus 2fil    % Space between floats on float page/column.       
\@fpbot 0pt plus 1fil    % Stretch at bottom of float page/column. (Must be

% called, where 'K' denotes 'i', 'ii', ... , 'vi'.  (I.e., \@listiii is
% called for a third-level list.)  By convention, \@listK should set
