<p>The depth of iteration is determined by <code>C(D,X)</code>.</p>
<p>For example,</p>
<pre>
#define C(D,X) <a href="comparison_less.htm#BOOST_PP_LESS_D">BOOST_PP_LESS_D</a>(D,<a href="tuple_elem.htm#BOOST_PP_TUPLE_ELEM">BOOST_PP_TUPLE_ELEM</a>(2,0,X),<a href="tuple_elem.htm#BOOST_PP_TUPLE_ELEM">BOOST_PP_TUPLE_ELEM</a>(2,1,X))
#define F(D,X) (<a href="inc.htm#BOOST_PP_INC">BOOST_PP_INC</a>(<a href="tuple_elem.htm#BOOST_PP_TUPLE_ELEM">BOOST_PP_TUPLE_ELEM</a>(2,0,X)),<a href="tuple_elem.htm#BOOST_PP_TUPLE_ELEM">BOOST_PP_TUPLE_ELEM</a>(2,1,X))
<a href="while.htm#BOOST_PP_WHILE">BOOST_PP_WHILE</a>(C,F,(0,3))
