When the referred-to spot does eventually 0178 appear in the source then LaTeX writes its location information to 0179 this <code>.aux</code> file. On the next invocation, LaTeX reads the 0180 location information from this file and uses it to resolve the 0181 reference, replacing the double question mark with the remembered 0182 location. 0183 </p> 0184 </dd> 0185 </dl> 0186 0187 <a name="index-_002elof-file"></a> 0188 <a name="index-list-of-figures-file"></a> 0189 <a name="index-_002elot-file"></a> 0190 <a name="index-list-of-tables-file"></a> 0191 <a name="index-_002etoc-file"></a> 0192 <a name="index-table-of-contents-file"></a> 0193 <a name="index-contents-file"></a> 0194 <p>LaTeX may produce yet more files, characterized by the filename 0195 ending.
