This sixth "hello" program uses
<FONT COLOR="770000">document.open()</FONT>,
<FONT COLOR="770000">document.write()</FONT> and
<FONT COLOR="770000">document.close()</FONT>
to reload a frame's contents.
<FONT COLOR="770000">Open</FONT>
resets the frame so that you can start to load new
information with your <FONT COLOR="770000">writes</FONT>.
When the writes complete, a <FONT COLOR="770000">close</FONT>
instructs the window to stop loading new information.<p>
You must designate a particular frame or window to write to, when writing
to other than the current frame. In this example, to write to the
JSChello frame, it must be given an explicit path. For more
details, please read about
<a href="../WINDOWS/WINOVR.HTM" target="JCcontent">frames and windows</A>.
<h3>Writing to a Frame</h3>
