87<blockquote>
88cartcursor should be called immediately after cartview. It gives the longitude,
89latitude, map value and pixel number
90corresponding to the cursor position in the window containing the map generated
91by orthview. For more details, or in case
92of problems under <B>Mac OS X</B>, see <A HREF="idl_mollcursor.htm#idl:mollcursor">mollcursor</A>.
