CALL SGTNU(N,UPX,UPY)
CALL SGTNV(N,VPX,VPY)
CALL SGTNR(N,RPX,RPY)
N (I) The length of array UPX, UPY. UPX, UPY (R) An array of length N. Give the (X, Y) coordinates of points defining a polygon in the UC. VPX, VPY (R) An array of length N. Give the (X, Y) coordinates of points defining a polygon in the VC. RPX, RPY (R) An array of length N. Give the (X, Y) coordinates of points defining a polygon in the RC.
