Hi Richard,

It's not especially straightforward to get a meridian line in Guide,
but it can be done. In reply to an inquiry about this in February 2003,
I posted http://groups.yahoo.com/group/guide-user/message/3089 . The
last few paragraphs describe what you need to do to get this to work.
(This is the solution proposed by Laurent, with some more details.)
