A clarification on the last message about Vortex and cookies:
$User and $Book would _not_ be automatically set on re-invokation.
$MyCookie would be set, but <readvars> must be used to URL-decode its
$User and $Book values:
<$ok = "User" "Book">
<readvars $ok $MyCookie>
User is $User
Book is $Book
My apologies for the omission.
