-<h3>Using Plain or primitive commands in LaTeX</h3>
-<p>It&rsquo;s well-known that LaTeX commands tend to be more complex, and to
-run more slowly than, any Plain (or primitive) command that they
-replace. There is therefore great temptation not to use LaTeX
-commands when macro programming. Nevertheless, the general rule is
-that you should use LaTeX commands, if there are seeming
-equivalents. The exception is when you are sure you know the
-differences between the two commands and you know that you need the
-Plain version. So, for example, use <code>\</code><code>mbox</code> in place of <code>\</code><code>hbox</code>
-unless you know that the extras that LaTeX provides in <code>\</code><code>mbox</code>
-would cause trouble in your application. Similarly, use
-<code>\</code><code>newcommand</code> (or one of its relatives) unless you need one of the
-constructs that cannot be achieved without the use of <code>\</code><code>def</code> (or friends).
-<p>As a general rule, any LaTeX text command will start a new
-paragraph if necessary; this isn&rsquo;t the case with Plain TeX
-commands, a fact which has a potential to confuse.
-<p>The commands <code>\</code><code>smallskip</code>, <code>\</code><code>medskip</code> and <code>\</code><code>bigskip</code> exist both
-in Plain TeX and LaTeX, but behave slightly differently: in Plain
-TeX they terminate the current paragraph, but in LaTeX they
-don&rsquo;t. The command <code>\</code><code>line</code> is part of picture mode in LaTeX,
-whereas it&rsquo;s defined as &ldquo;<code>\</code><code>hbox</code><code> to </code><code>\</code><code>hsize</code>&rdquo; in
-Plain TeX. (There&rsquo;s no equivalent for users of the Plain TeX command in
-LaTeX: an equivalent appears as the internal command <code>\</code><code>@@line</code>).
-<p>Maths setting shows a case where the LaTeX version <em>is</em>
-essentially equivalent to the TeX primitive commands: the LaTeX
-<code>\</code><code>(</code><code> ... </code><code>\</code><code>)</code> does essentially no different to the
-TeX <code>$ ... $</code>
-(except for checking that you&rsquo;re not attempting to open a maths
-environment when you&rsquo;re already in one, or vice versa).
-However, <code>\</code><code>[</code><code> ... </code><code>\</code><code>]</code> <em>isn&rsquo;t</em> the same as
-<code>$$ ... $$</code>: the TeX version, used
-in LaTeX, contrives to miss the effect of the class option
-<code>fleqn</code>.
-<p>Font handling is, of course, wildly different in Plain TeX and
-LaTeX: even the LaTeX equivalent of the Plain TeX
-font-loading command (<code>\</code><code>newfont</code>) should be avoided wherever
-possible: the possibilities of confusion with constructs that vary
-their behaviour according to the font size that LaTeX has recorded
-are (sadly) legion. A really rather funny example is to be had by
-saying:
-<blockquote>
-<pre>
-\documentclass{article}
-\begin{document}
-\font \myfont=cmr17 scaled 2000
-\myfont
-\LaTeX
-\end{document}
-</pre>
-</blockquote><p>
-(the reader is encouraged to try this). The &ldquo;A&rdquo; of LaTeX
-has pretty much disappeared: LaTeX sets the &ldquo;A&rdquo; according to
-<em>its</em> idea of the font size (10pt), but &ldquo;<code>\</code><code>myfont</code>&rdquo; is more
-than three times that size.
-<p>Another &ldquo;<code>\</code><code>myfont</code>&rdquo; example arises from an entirely different
-source. The mini-document:
-<blockquote>
-<pre>
-\documentclass{article}
-\begin{document}
-\font \myfont=ecrm1000
-{\myfont par\`a}
-\end{document}
-</pre>
-</blockquote><p>
-gives you &ldquo;German low double quotes&rdquo; in place of the grave accent.
-This problem arises because <i>ecrm1000</i> is in a different
-<a href="FAQ-whatenc.html">font encoding</a> than LaTeX is expecting &mdash; if you
-use LaTeX font commands, all the tiresome encoding issues are
-solved for you, behind the scenes.
-<p>So, whether you&rsquo;re dealing with a one-off font or a major new family, you
-are far more likely to be satisfied with the LaTeX file selection
-system, so it&rsquo;s worth investing a small amount of effort to write
-declarations of the font&rsquo;s family and how it should be loaded. For
-details of the commands you need, see the LaTeX font usage guide,
-<i>fntguide</i>: this may be viewed on the archive, but you should
-find a copy of the document in your own system.
