Yes, e.g., ENVI> xy = get_evf_point_coordinates('C:\data
\my_evf_file.evf')

FUNCTION GET_EVF__POINT_COORDINATES, evf_fname
evf_id = envi_evf_open(evf_fname)
envi_evf_info, evf_id, num_recs=n
xy = dblarr(2,n)
for i=0L,n-1 do xy[*,i] = envi_evf_read_record(evf_id, i)
envi_evf_close, evf_id
return, xy
END
