% This test file generates the output shown on the opposite page. |01
% It's a bit complex because it tries to illustrate lots of stuff.|02
% TeX ignores commentary (like this) that follows a `%' sign.     |03

% First the standard output style is changed slightly:            |05
\hsize=29pc % The lines in this book are 29 picas wide.           |06
\vsize=42pc % The page body is 42 picas (not counting footlines). |07
\footline={\tenrm Footline\quad\dotfill\quad Page \folio}         |08
\pageno=1009 % This is the starting page number (don't ask why).  |09
% See Chapter 23 for the way to make other page format changes via|10
% \hoffset, \voffset, \nopagenumbers, \headline, or \raggedbottom.|11

\vspace 1in % This makes an inch of blank space (1in=2.54cm).     |13
\centerline{\bf A Bold, Centered Title}                           |14
\smallskip % This gives a little extra space between lines here.  |15

% Now we use \beginsection to introduce part 1 of the document.   |17
\beginsection 1. Plain \TeX nology % The next line must be blank! |18

The first paragraph of a new section is not indented.             |20
\TeX\ recognizes the end of a paragraph when it comes to a blank  |21
line in your manuscript file. % or to a `\par': see below.        |22
                                                                  |23
Subsequent paragraphs {\it are\/} indented.\footnote*{The amount  |24
 of indentation can be changed by changing a parameter called     |25
{\tt\char`\\parindent}. Turn the page for a summary of \TeX's most|26
important parameters.} (See?) The computer breaks a paragraph's   |27
text into lines in a interesting way---see reference~[1]---and hy%|28
phenates words automatically  when necessary.                     |29
                                                                  |30

\narrower\narrower % This brings the margins in (see Chapter 14). |32
\noindent \llap{``}If there hadn't been room for this material on |33
the present page, it would have been inserted on the next one.''  |34
