It is possible to +<a href="ltx-165.html">split the input</a> into several files using: +<ul> +<li><a href="ltx-245.html"><tt>\include</tt></a> +<li><a href="ltx-248.html"><tt>\input</tt></a> +</ul> +<p> +Space characters separate words. Two space characters in a row are +equivalent to a single space character. The end of line is also +equivalent to a space character. (However, a percent sign, +<a href="ltx-434.html"><tt>%</tt></a>, can end a line without +generating a space character.) Generally, space characters at the beginning +of a line are ignored. +<p> +An empty or blank line between two lines of text defines +<a href="ltx-111.html">a new paragraph</a>. +Two blank lines are equivalent to one. +<h2>Special Characters</h2> +The following ten characters are <a href="ltx-164.html">Special LaTeX +Characters</a>: +<pre><tt> $ & % # _ { } ~ ^ \ </tt> +</pre> +If entered directly in the input they cause LaTeX to do something special. +You can get the following seven of them into your document by simply +preceding them with a backslash (<tt>\</tt>): +<pre><tt> $ & % # _ { } </tt> +</pre> +To get the other three (<tt> ~ ^ \ </tt>) in +your output requires <a href="ltx-164.html">more work</a>. + +<h2>LaTex Commands</h2> +Commands take one of two forms +<ul><li>a backslash (<tt>\</tt>) followed by a single special character + <li>a bacslash (<tt>\</tt>) followed by a string of letters +</ul> +The second case is case-sensitive; +<a href="ltx-405.html"><tt>\Gamma</tt></a> is different from +<a href="ltx-405.html"><tt>\gamma</tt></a>. +These commands are terminated by a nonletter, i.e., a blank, a number, +a punctuation mark or special character. +<p> +Commands may have mandatory arguments, which are input in braces +(<tt>{}</tt>). +They may also have optional arguments, which are input in square brackets +(<tt>[]</tt>). +<p> +For commands which produce text a trailing blank may be interpreted as the +end of the command, which does not automatically create a space, so + you may have to do something to create an +<a href="ltx-431.html">interword space</a> after this text. + +<h2><a name="structure">Structure of Input</a></h2> +LaTeX input normally begins with a +<a href="ltx-22.html"><tt>\documentstyle</tt></a> command.
