The OUTPUT section in the rea-files controls what data will be dumped into a fld-file. 
So if you want to dump the coordinates just set:

  ***** OUTPUT FIELD SPECIFICATION *****
           X SPECIFICATIONS FOLLOW
  T      COORDINATES

Sometimes you don't want to dump the coordinates at every I/O step (to save space). In this case we the following in usrchk():

      ifxyo = .true. ! Turn on xyz output
      if (istep.gt.iostep) ifxyo = .false.  ! Turn off xyz output after first dump
