Ah, I'm sorry I've misunderstood your last mail.
If LYclrtoeol was used, would some other characters, which should be
shown, be disappeared?
I tried to use LYclrtoeol instead of the explicit loop, but I found
a bad result in this html (I couldn't found 'Hello!').
<html>
<head>
<title>foo</title>
</haed>
<body>
<form action="foo.cgi">
<input type="text" name="text"> Hello!
</form>
</body>
</html>
