<h1>document.write (out-of-line) test</h1>
<p>This test uses the open, write and close methods of a
document to construct a document. It tests the "out-of-line"
capabilties of document.write i.e. the ability to use
document.write to create an entirely new document.</p>
<form>
<p>Use this button to create a new window. If one already
exists, we'll use it.
<INPUT TYPE="button" NAME="newwin" VALUE="New Window" onClick="newWin(); return true;">
</p>
<p>Use this button to write the new value of a counter into
the document. If the document was previously closed, it will be
reopened (and the old contents will be destroyed.
<INPUT TYPE="button" NAME="incrwrite" VALUE="Write" onClick="incrWrite(); return true;">
</p>
<p>Use this button to close the document. Subsequent writes will rewrite
the document.
<INPUT TYPE="button" NAME="closedoc" VALUE="Close Document" onClick="closeDoc(); return true;">
