DESCRIPTION
cartcursor should be called immediately after cartview. It gives the longitude,

by orthview. For more details, or in case
of problems under Mac OS X, see mollcursor.

EXAMPLE:
After cartview has read in a map and generated
its cartesian projection, cartcursor is run to determine the
position and flux of bright synchrotron sources, for example.
