%%% MISCELLANEOUS:
% First, a utility command that gives lowercase small capitals:
\def\LCSmCaps#1{{\let\ZZ=\&\def\&{{\sevenrm\:\ZZ\:}}\Smallcaps
\xspaceskip=.1667em\relax
\lowercase\expandafter{#1}}}
% Next, utilities to save typing; the first of these typesets references
% in the correct format.
\def\Ref#1[#2]{\LCSmCaps{#1}{\Smallrm [#2]}}
\def\[#1]{{\Sansserif #1}}
%----------------------------------------------------------------------------
%%% CHAPTER AND SECTION FORMATTING:
\newskip\BelowTitleSkip \BelowTitleSkip=4.5pc plus .5pc % Note: 1pc=12pt
\newcount\StartAnew
\newtoks\NameofChapter
\newtoks\SectionLabel
\newcount\SectionNumber
\newcount\ChapterNumber
\newcount\NumberSectionLbl \NumberSectionLbl=1 % An indicator; see below.
\def\NoSections{\NumberSectionLbl=0} % For chapters without sections.
% The command that creates the format for chapter titles:
\outer\def\Title #1/#2\par{\ChapterNumber=#1
{\parindent0pt
\ifnum\ChapterNumber>0 {\NumFont\the\ChapterNumber}\medskip\fi
\pretolerance1000 \TitleFonts \righthyphenmin=50

\NameofChapter={\tensl#2}\StartAnew=1 \SectionNumber=0
\SectionLabel={}\mark{}\vskip\BelowTitleSkip\relax
\noindent\ignorespaces}% _%
% The command that follows does several things. It tests the current
% position on the page by comparing `\pagetotal' and a reduced value of
% `\pagegoal'. If there is enough space available to start a new section on
% the current page, the section begins there (after a vertical skip);
% otherwise, the section begins on the next page. The command also defines
% what is to go in the `token lists' called `\LMargStuff' and `\RMargStuff'
% (see the output routine at the end of this file) and it `marks' the material
% that is to go in the margin. Further, the command typesets the section title
% and section number.
\def\NewSection #1\par{\par \dimen0=\pagegoal \advance\dimen0 by-120pt
\ifdim\pagetotal>\dimen0
\ifdim\pagetotal<\pagegoal \EndPage

% The next few commands go towards creating the large, `illuminated'
% opening letter that starts each chapter. The commands are crude,
% `one-shot' ones, meant just to serve for this book. But, they may
% help suggest how more general ones may be constructed.
% The first command, `\Patbox', fills the edges of a box of fixed size
% with nonletter characters from a given font (the height of each character
% is first examined, and only ones of height above a certain value are used).
\def\Patbox #1#2{\vbox to 44pt{\hsize42pt \lineskip 0pt

% Next, the font that will be used for the large letter is chosen:
\font\BigFancy=cmr7 scaled 5160
% Finally, the main command is constructed. Its first argument is the
% font that will be used for the boundary pattern (only 5-point fonts really
% work well, and then too not all of them); the second, the starting
% character position in that font; the third, the first letter of the
% paragraph that is to just open; the fourth and fifth, the first two
% words of that paragraph (spaces are used to `delimit' these arguments;
% the words will appear in small capitals.

\vbox to44pt{\hsize42pt\vfil

}}\vskip-3\baselineskip}\hskip4pt}{\Smallcaps #4\ #5\ }}
% FOR EXAMPLE:
% `\Fancy{cmbsy5}{12} Let us begin with a bang.'
% This will cause a large `L' to appear, surrounded by the taller characters
% of the font cmbsy5, starting with character number 12; the first two
% words will also appear capitalized.
