SUBROUTINE FKLPRO(JPL,IERR)
**********************************************************************
* *
* Project the state vector and its covariance from plane JPL to *
* plane JPL+1, including multiple scattering. *
* *
* ERROR CONDITIONS; *
* IERR = 0 ; normal termination *
* -> IERR = 101 ; no filtered vector at JPL *
* IERR = 5 ; projection to JPL+1 already done *
* -> IERR = 111 ; failure to invert projected covariance *
* *
* -> Fatal errors *
