|

|
|
<p>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:
|
||
|
|
</p><div class="smallexample">
|
||
|
|
<pre class="smallexample">"SECTION" = 9;
|
||
|
|
"with a space" = "also with a space" + 10;
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>Since symbols can contain many non-alphabetic characters, it is safest
|
||
|
|
to delimit symbols with spaces. For example, ‘<samp>A-B</samp>’ is one symbol,
|
||
|
|
whereas ‘<samp>A - B</samp>’ is an expression involving subtraction.
|
||
|
|
