|
<p><a name="index-built_002din-values-16"></a>The following variables are special and can be accessed anytime. They can
|
||
|
|
even be overwritten.
|
||
|
|
<pre class="verbatim">args, return, temp, stdin, stderr, stdout, zero, true, false, none, @pi,
|
||
|
|
@e, cwd, cpd, fnm
|
||
|
|
</pre>
|
||
|
|
<code>zero</code> is a fake writable file that does nothing. <code>none</code> is an
|
||
|
|
abstract variable with an internal value of.. none. <code>@pi</code> is
|
||
|
|
Pi. <code>@e</code> is Euler's number. <code>cwd</code> is the directory from which
|
||
|
|
Enigma is run, <code>cpd</code> is the directory in which the current program
|
||
|
|
file resides, and <code>fnm</code> is the filename of the current program
|
||
|
|
file. The rest are self-explanatory — and <code>args</code>, <code>return</code>
|
||
|
|
and <code>temp</code> are extra special.
