INQPA

       SUBROUTINE  INQPA (PARRAY)
 C$    (Inquire Viewing Parameters)
 C$    Return the  current values  of  all viewing  parameters  in
 C$    PARRAY(*), as follows:
 C$
 C$    1-3.....View Reference Point in world coordinates.
 C$    4-6.....View Plane Normal in world coordinates.
 C$    7.......View Plane Distance in world coordinates.
 C$    8.......Front Distance in world coordinates.
 C$    9.......Back Distance in world coordinates.
 C$    10......Projection type (0.0 = parallel, else perspective).
 C$    11-13...Projective point in world coordinates relative to
 C$            View Reference Point.
 C$    14-17...Window boundaries in world coordinates.
 C$    18-20...View Up Vector in world coordinates relative to
 C$            View Reference Point.
 C$    21-26...Viewport boundaries in NDC space.
 C$
 C$    Users  should  normally  not  enter  values  in   PARRAY(*)
 C$    themselves.  The purpose of  this routine is primarily  for
 C$    saving viewing parameters when a temporary change in a  few
 C$    of them is required locally.  The original values can  then
 C$    be restored by a call to SETPA.
