Yes, but I write only for those who can read English, the language still
spoken in England.  Dutch and Danes, in particular, are very good at it.
See /via/ <http://www.merlyn.demon.co.uk/quotings.htm#FredHoyle>.

Well, that's an improvement; but not a very useful one.  It reminds me
of a DOS clone which had an error in comment - but not in code -
concerning the behaviour in the year AD 2400.  The code was written
after I replaced IE7.  Implemented, tested, for public release later
this evening.

H'mmm - I wonder what that alert was for ... especially as it does not
get called when $.htm is used, and that's the only case-independent
"$.htm" in the file, and the local $.htm is really $.HTM.

Proven to my continued satisfaction by test.

No; CSS!=JS.  I mean words such as appear because of the likes of
        document.write(new Date())
or
        document.getElementById("DM").innerText =
          new Date().getMonth()-1 ? "Feb" : "notFeb"

Well, here's an approximately legal Web page :

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<HTML>
<HEAD><TITLE>JRS</TITLE></HEAD>
<BODY><center>centre</center></BODY>
</HTML>

With that loaded into <iframe ID=Z></iframe>, I have code which will see
one "centre" and two "center".  I want alternative code which will see
one "centre" and zero "center".
