<h2><a name="Internal Operators"></a>Internal Operators</h2>

<p>
  The following operators are defined for internal use by developers.
  In general these will be undefined after initialization is complete.
</p>

<dl>
<dt><code>&lt;name&gt; &lt;array&gt; .makeoperator &lt;operator&gt;</code></dt>
<dd>Constructs and returns a new operator that is actually the given
procedure in disguise.  The name is only used for printing.  The operator
has the executable attribute.</dd>

<p>
Operators defined in this way do one other thing besides running the
procedure: if an error occurs during the execution of the procedure, and
there has been no net reduction in operand or dictionary stack depth, the
operand or dictionary stack pointer respectively is reset to its position
at the beginning of the procedure.</p>
</dl>
