<h4 class="subsection">3.10.3 Symbol Names</h4>

<p><a name="index-symbol-names-562"></a><a name="index-names-563"></a><a name="index-quoted-symbol-names-564"></a><a name="index-g_t_0022-565"></a>Unless quoted, symbol names start with a letter, underscore, or period
and may include letters, digits, underscores, periods, and hyphens. 
Unquoted symbol names must not conflict with any keywords.  You can
specify a symbol which contains odd characters or has the same name as a
keyword by surrounding the symbol name in double quotes:
<pre class="smallexample">     "SECTION" = 9;
     "with a space" = "also with a space" + 10;
</pre>
   <p>Since symbols can contain many non-alphabetic characters, it is safest
to delimit symbols with spaces.  For example, &lsquo;<samp><span class="samp">A-B</span></samp>&rsquo; is one symbol,
whereas &lsquo;<samp><span class="samp">A - B</span></samp>&rsquo; is an expression involving subtraction.
