  SEVERITY:  F

  MESSAGE TEXT:  Invalid reference to name in implied-DO list

  EXPLANATION:  A control parameter expression in an implied-DO list
  in a DATA statement contained a name that was not the name of a
  control variable within the scope of any implied-DO list.  Example:

      DATA (A(J), J=1,10),(B(I), I=J,K) /1001./

  Both J and K in the second implied-DO list are invalid names.
