   Calculate z-vertex by weighted mean

   INFTKR - FTKR bank index                         
   NFTKR  - The number of FTKR rows (= size of work bank)                       
   ZNOM   - the nominal z-vertex position                                       
   LFIRST - TRUE for the first call (primary vertex)

   FVVEC - the four words of the FTGR bank          
   IERR  - non-zero if the weighted mean fails
