PLNR3

       SUBROUTINE  PLNR3 (DXARAY,INCX,DYARAY,INCY,DZARAY,INCZ,N)
 C$    (Polyline Relative 3-D)
 C$    Beginning at the current point, draw line segments to  each
 C$    of  N  points  in  turn.    (DXARAY(*),DYARAY(*),DZARAY(*))
 C$    define the relative displacements from the preceding point.
 C$    INCX,  INCY,  and  INCZ   are  the  displacements   between
 C$    successive X, Y, and  Z values in  the arrays.  These  will
 C$    normally be all 1.  If an increment INCX, INCY, or INCZ  is
 C$    negative, the starting  vertex is  taken as  (1-N)*INC +  1
 C$    instead of  1, so  that  the array  is stepped  through  in
 C$    reverse order.
