-<h3>Preventing page breaks between lines</h3>
-<p/>One commonly requires that a block of typeset material be kept on the
-same page; it turns out to be surprisingly tricky to arrange this.
-<p/>LaTeX provides a <code>samepage</code> environment which claims it
-does this sort of thing for you. It proceeds by setting infinite
-penalties for all sorts of page-break situations; but in many
-situations where you want to prevent a page break,
-<code>samepage</code> doesn&rsquo;t help. If you&rsquo;re trying to keep running
-text together, you need to end the paragraph inside the environment
-(see <a href="FAQ-paraparam.html">preserving paragraph parameters</a>).
-Also, if the things you are trying to keep together insert their own
-pagebreak hints, <code>samepage</code> has no power over them: a good
-example is list items &mdash; they suggest page breaks between them. Even
-if <code>samepage</code> <em>does</em> work, it&rsquo;s likely to leave stuff
-jutting out at the bottom of the page.
-<p/>A convenient trick is to set all the relevant stuff in a <code>\</code><code>parbox</code>
-(or a <code>minipage</code> if it contains things like verbatim text
-that may not be in the argument of a <code>\</code><code>parbox</code>). The resulting box
-certainly <em>won&rsquo;t</em> break between pages, but that&rsquo;s not to say that
-it will actually do what you want it to do: again, the box may be left
-jutting out at the bottom of the page.
-<p/>Why do neither of these obvious things work? Because TeX can&rsquo;t
-really distinguish between infinitely awful things.
-<code>Samepage</code> will make any possible break point &ldquo;infinitely
-bad&rdquo; and boxes don&rsquo;t even offer the option of breaks, but if the
-alternative is the leave an infinitely bad few centimetres of blank
-paper at the bottom of the page, TeX will take the line of least
-resistance and do nothing.
-<p/>This problem still arises even if you have <code>\</code><code>raggedbottom</code> in
-effect: TeX doesn&rsquo;t notice the value of <em>that</em> until it starts
-actually shipping a page out. One approach is to set:
-<blockquote>
-<pre>
-\raggedbottom
-\addtolength{\topskip}{0pt plus 10pt}
-</pre>
-</blockquote><p>
-The <code>10pt</code> offers a hint to the output routine that the column is
-stretchable; this will cause TeX to be more tolerant of the need to
-stretch while building the page. If you&rsquo;re doing this as a temporary
-measure, cancel the change to <code>\</code><code>topskip</code> by:
-<blockquote>
-<pre>
-\addtolength{\topskip}{0pt plus-10pt}
-</pre>
-</blockquote><p>
-as well as resetting <code>\</code><code>flushbottom</code>. (Note that the <code>10pt</code> never
-actually shows up, because it is overwhelmed when the page is shipped
-out by the stretchability introduced by <code>\</code><code>raggedbottom</code>; however, it
-could well have an effect if <code>\</code><code>flushbottom</code> was in effect.)
-<p/>An alternative (which derives from a suggestion by Knuth in the
-TeXbook) is the package <i>needspace</i> or the <i>memoir</i> class,
-which both define a command <code>\</code><code>needspace</code> whose argument tells it
-what space is needed. If the space isn&rsquo;t available, the current page
-is cleared, and the matter that needs to be kept together will be
-inserted on the new page. For example, if 4 lines of text need to be
-kept together, the sequence
-<blockquote>
-<pre>
-\par
-\needspace{4\baselineskip}
-% the stuff that must stay together
-&lt;text generating lines 1-4&gt;
-% now stuff we don't mind about
-</pre>
-</blockquote><p>
-Yet another trick by Knuth is useful if you have a sequence of small
-blocks of text that need, individually, to be kept on their own page.
-Insert the command <code>\</code><code>filbreak</code> before each small block, and the
-effect is achieved. The technique can be used in the case of
-sequences of LaTeX-style sections, by incorporating <code>\</code><code>filbreak</code>
-into the definition of a command (as in
-<a href="FAQ-patch.html">patching commands</a>). A simple and effective
-patch would be:
-<blockquote>
-<pre>
-\let\oldsubsubsection=\subsubsection
-\renewcommand{\subsubsection}{%
- \filbreak
- \oldsubsubsection
-}
-</pre>
-</blockquote><p>
-While the trick works for consecutive sequences of blocks, it&rsquo;s
-slightly tricky to get out of such sequences unless the sequence is
-interrupted by a forced page break (such as <code>\</code><code>clearpage</code>, which may
-be introduced by a <code>\</code><code>chapter</code> command, or the end of the document).
-If the sequence is not interrupted, the last block is likely to be
-forced onto a new page, regardless of whether it actually needs it.
-<p/>If one is willing to accept that not everything can be accomplished
-totally automatically, the way to go is to typeset the document and to
-check for things that have the potential to give trouble. In such a
-scenario (which has Knuth&rsquo;s authority behind it, if one is to believe
-the rather few words he says on the subject in the TeXbook) one can
-decide, case by case, how to deal with problems at the last
-proof-reading stage. The alternatives are to insert <code>\</code><code>clearpage</code>
-commands as necessary, or to use <code>\</code><code>enlargethispage</code>. Supposing you
-have a line or two that stray: issue the command
-<code>\</code><code>enlargethispage{2<code>\</code><code>baselineskip</code>}</code> and two lines are
-added to the page you&rsquo;re typesetting. It depends on the document
-whether this looks impossibly awful or entirely acceptable, but the
-command remains a useful item in the armoury.
