 C$    Demonstration  program   for   labelling   in   curvilinear
 C$    coordinates.  The  principal  point  of  interest  in  this
 C$    demonstration is that inclusion  of a pen-movement  routine
 C$    as an  argument to  a symbol  drawing routine  permits  the
 C$    mapping of  software-generated  characters  onto  arbitrary
 C$    coordinate systems.  It  also shows that  the axis  drawing
 C$    option of GRFIG  (called from GRFCX)  will faithfully  draw
 C$    the coordinate axes of the selected coordinate system.
