Hi Tom,
I've updated the documentation at
http://www.projectpluto.com/mar_fmt.htm#1
to reflect the RA oddity. (It's the result of a poor choice I made
a long time ago, back when I didn't know any better.)
Guide 8.0 from the CD doesn't have the 98xx message capability. I
think it would only be found in the currently-posted version.
