33<H2>Description</H2>
34<P>This function sets the specified <a href="GDLObj.html"><CODE>GDLObj</CODE></a> as the current structure. All the commands which act upon the current <a href="GDLObj.html"><CODE>GDLObj</CODE></a> will now act upon <SPAN class="argument">dl</SPAN> until a different <A href="GDLObj.html"><CODE>GDLObj</CODE></A> is set as current. Note that all of the GD graphics commands operate on the current <a href="GDLObj.html"><CODE>GDLObj</CODE></a>.</P>
35<P>When you finish working with the current <a href="GDLObj.html"><CODE>GDLObj</CODE></a>, setting <CODE>NULL</CODE> to it is recommended. This will help avoid potential problems and aid in debugging if you forget to set a different structure as the current <a href="GDLObj.html"><CODE>GDLObj</CODE></a>.</P>
