To copy a branch, we use recursion and the <A HREF="copy_item.shtml">CopyItem()</A>
function to accomplish our task.

<PRE><TT><FONT COLOR="#990000">// CopyBranch&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Copies all items in a branch to a new location
// Returns&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - The new branch node
