[Wylug-help] javascript function defined???

[Towle, William]

  In a simple test with just a <script language="javascript"
src="include.js"></script>, a subsequent document.writeln(typeof(foo));
works as expected in both IE and Konqueror for me.

  It is worth noting that IE appears to be somewhat temperamental about
the other HTML in the
containing page. For example, if I have a stray '<' outside a comment
(which should technically be
&lt; of course), it goes on to report the function is undefined even
though include.js hasn't
changed.
  There doesn't appear to be a "page has errors" warning emitted for
this.

HTH,
  W.
