\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.

% ****************************************
% * PAGE LAYOUT *
% ****************************************
%
% 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 21pt % Left margin on odd-numbered pages.
\evensidemargin 59pt % Left margin on even-numbered pages.
\marginparwidth 85pt % Width of marginal notes.
\else % Values for one-sided printing:
\oddsidemargin 39.5pt % Note that \oddsidemargin = \evensidemargin
\evensidemargin 39.5pt
\marginparwidth 68pt
\fi
\marginparsep 10pt % 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 536.5pt.
% \textheight is the height of text (including footnotes and figures,
% excluding running head and foot).

\textheight = 36\baselineskip
\advance\textheight by \topskip
\textwidth 390pt % 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 8.4pt % Height of strut placed at the beginning of every
% footnote = height of normal \footnotesize strut,
% so no extra space between footnotes.

\skip\footins 10.8pt 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 14pt plus 2pt minus 4pt % 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 14pt plus 4pt minus 4pt % 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 14pt plus 2pt minus 4pt % 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 10pt plus 2fil % Space between floats on float page/column.
\@fpbot 0pt plus 1fil % Stretch at bottom of float page/column. (Must be
% 0pt plus ... )

% DOUBLE-COLUMN FLOATS IN TWO-COLUMN MODE.
\@dblfptop 0pt plus 1fil % Stretch at top of float page. (Must be 0pt plus ...)
\@dblfpsep 10pt plus 2fil % Space between floats on float page.
\@dblfpbot 0pt plus 1fil % Stretch at bottom of float page. (Must be
% 0pt plus ... )
% MARGINAL NOTES:
%
\marginparpush 7pt % Minimum vertical separation between two marginal
% notes.


% ****************************************
% * PARAGRAPHING *
% ****************************************
%
\parskip 0pt plus 1pt % Extra vertical space between paragraphs.
\parindent 1.5em % Width of paragraph indentation.
%\topsep 10pt plus 4pt minus 6pt % Extra vertical space, in addition to
% \parskip, added above and below list and
% paragraphing environments.
\partopsep 3pt plus 2pt minus 2pt % Extra vertical space, in addition to
% \parskip and \topsep, added when user
% leaves blank line before environment.
%\itemsep 5pt plus 2.5pt minus 1pt % Extra vertical space, in addition to
% \parskip, added between list items.
% See \@listI for values of \topsep and \itemsep

\@beginparpenalty -\@lowpenalty % Before a list or paragraph environment.
\@endparpenalty -\@lowpenalty % After a list or paragraph environment.
\@itempenalty -\@lowpenalty % Between list items.

% \clubpenalty % 'Club line' at bottom of page.
% \widowpenalty % 'Widow line' at top of page.

% * SECTIONS *
% ****************************************
%

% \secdef{UNSTARCMDS}{STARCMDS} :
% When defining a sectionioning command without using
% \@startsection, you can use \secdef as follows:
% \def\part { ... \secdef \CMDA \CMDB }
% \def\CMDA [#1]#2{ ... } % Command to define \part[...]{...}
% \def\CMDB #1{ ... } % Command to define \part*{...}

\def\part{\par % New paragraph
\addvspace{4ex} % Adds vertical space above title.
\@afterindentfalse % Suppresses indent in first paragraph. Change
\secdef\@part\@spart} % to \@afterindenttrue to have indent.

\def\@part[#1]#2{\ifnum \c@secnumdepth >\m@ne % IF secnumdepth > -1

\fi % FI
\huge \bf % Select \huge boldface.
#2\markboth{}{}\par } % Print title and set heading marks null.
\nobreak % TeX penalty to prevent page break.
\vskip 3ex % Space between title and text.

\def\@spart#1{{\parindent 0pt \raggedright
\huge \bf
#1\par} % Title.
\nobreak % TeX penalty to prevent page break.

\@afterheading % Routine called after part and

% \@startsection {NAME}{LEVEL}{INDENT}{BEFORESKIP}{AFTERSKIP}{STYLE}
% optional * [ALTHEADING]{HEADING}
% Generic command to start a section.
% NAME : e.g., 'subsection'
% LEVEL : a number, denoting depth of section -- e.g., section=1,
% subsection = 2, etc. A section number will be printed if
% and only if LEVEL < or = the value of the secnumdepth
% counter.
% INDENT : Indentation of heading from left margin
% BEFORESKIP : Absolute value = skip to leave above the heading.
% If negative, then paragraph indent of text following
% heading is suppressed.
% AFTERSKIP : if positive, then skip to leave below heading,
% else - skip to leave to right of run-in heading.
% STYLE : commands to set style
% If '*' missing, then increments the counter. If it is present, then
% there should be no [ALTHEADING] argument. A sectioning command
% is normally defined to \@startsection + its first six arguments.

% ****************************************
% * LISTS *
% ****************************************
%

% The following commands are used to set the default values for the list
% environment's parameters. See the LaTeX manual for an explanation of
% the meanings of the parameters. Defaults for the list environment are
% set as follows. First, \rightmargin, \listparindent and \itemindent
% are set to 0pt. Then, for a Kth level list, the command \@listK is
% called, where 'K' denotes 'i', 'ii', ... , 'vi'. (I.e., \@listiii is
% called for a third-level list.) By convention, \@listK should set
% \leftmargin to \leftmarginK.
%
% For efficiency, level-one list's values are defined at top level, and
% \@listi is defined to set only \leftmargin.

\leftmargini 2.5em
\leftmarginii 2.2em % > \labelsep + width of '(m)'
\leftmarginiii 1.87em % > \labelsep + width of 'vii.'
