*  Given:
*      VA      dp(3)     first vector
*      VB      dp(3)     second vector
*
*  Returned:

      DOUBLE PRECISION VA(3),VB(3),VC(3)

      DOUBLE PRECISION VW(3)
      INTEGER I


*  Form the vector product VA cross VB
      VW(1)=VA(2)*VB(3)-VA(3)*VB(2)
      VW(2)=VA(3)*VB(1)-VA(1)*VB(3)
      VW(3)=VA(1)*VB(2)-VA(2)*VB(1)

*  Return the result
      DO I=1,3
         VC(I)=VW(I)
      END DO
