Sure - RTFM :-) But handy shortcuts are also an essential part of ones programming toolbox.
The four GET statements are very simple to use, and the MAP file format (header) hasn't changed for a loooong time. Best regards/Med venlig hilsen Lars V.

Primary and most accurate (open) source for information is the MITAB library (read the source code) unless you have access to the MapInfo Corp.'s own information. More accessible is this document, which may not be 100% accurate: www.routeware.dk/notes.html.
