INQTR

       SUBROUTINE  INQTR (TWCNDC)
 C$    (Inquire World-To-Device Transformation Matrix)
 C$    Return in  TWCNDC(4,4) the  current transformation  mapping
 C$    world coordinates  to  Normalized Device  Coordinates.   No
 C$    equivalent   routine   is   provided   for   setting    the
 C$    transformation matrix directly.   Instead, INQPA and  SETPA
 C$    may be used  to save  and restore  the viewing  parameters,
 C$    from which a  new transformation matrix  may be  calculated
 C$    internally.
 C$
 C$    This routine is  provided primarily  to allow  the user  to
 C$    enjoy  the  convenient   parametrization  of  the   viewing
 C$    transformation by the  CORE system,  and then  to find  out
 C$    what the matrix  actually is,  perhaps for use  as a  world
 C$    coordinate modelling matrix.
