     I'm not saying that the following is any "better" than the above, but
here's how I would do it, without recursion.
Retry : Boolean := True;
I     : ...     := ...;
...
while Retry loop
   Retry := False;
   while I < ... and not Retry loop
      ...
      if entry_type = continue then
         ...
         Retry := True;
      end if;
      I := ...; -- e.g., I + 1 or ...'Succ(I)
   end loop;
end loop;
     Again, I'm not saying this is better, but my point is that you could
"fix" the goto without recursion.

to turn the bulb, and four to file an Environmental Impact Statement.
