<p><a name="index-symbol-names-463"></a><a name="index-names-464"></a><a name="index-quoted-symbol-names-465"></a><a name="index-_0022-466"></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, <span class="samp">A-B</span> is one symbol,
|
|
whereas <span class="samp">A - B</span> is an expression involving subtraction.
