  Clarify please.  It appears that somewhere you need to establish the
relation between, eg, -2 and EYYY.  Is
   case res is
      when -1 => raise EXXX;
      when -2 => raise EYYY;
      ...
preferable to
   jump : constant array(...) of Exception_ID :=
     (-1 => EXXX'Identity,
      -2 => EYYY'Identity,
      ...
Of course one always wonders if a jump table is the best approach for the
problem at hand.
