Add bend line (point definition of the bend line)

C call:

C     CALL PVB441 (IN,IP,XP,YP,IRET)

C     

C     The following variables must be defined beforehand:

C     

C     IN    : Bend number

C     IP    : 1 = Start point, 2 = End point

C     XP,YP : Coordinate of the point

C     IRET  : is not evaluated, but must be specified

C     

C     Example:

C     

C     -----------------------------------

C->      2  Cutout 2 deg frdm

C     -----------------------------------

C     

      INDEX         = INDEX + 1

      RXDEF1(INDEX) =               -5.0000

      RYDEF1(INDEX) =  YMAIN -      50.0000

      RXDEF2(INDEX) =               40.0000

      RYDEF2(INDEX) =  YMAIN -      -5.0000

      IN  = 1

      XP  = RXDEF2(INDEX)

      YP  = YMAIN - 10

      CALL PVB441 (IN,2,XP,YP,IRET)
