[MITgcm-support] Ptracers

[Hong Zhang]

In pkg/ptracers, I need to output ptracer fields
using ptracers_write_state.F,
but here
        CALL WRITE_REC_XYZ_RL(suff,
     &      pTracer(1-Olx,1-Oly,1,1,1,iTracer),iRec,myIter,myThid)

why just limit to  (1-Olx,1-Oly,1,1,1) (seems one grid point)
but not the whole fields?

thanks,

Hong
