Nice he he he. Hum, I prefer to wait a while to see
others' opinions.
Provisorily for your tests you could replace at line 1016 of pascal.y

    | {pascalhelp.put_line("WHEN OTHERS=> Null; ");}   -- EMPTY

with:

    |  -- EMPTY

BTW the "null;" for empty statements is not avoided for the case
of an empty statement appearing in a sequence, like

if abc then begin
  x;
  y; { empty statement after y ! }
end;

(NB: the ';' is a separator in Pascal) so there will
be protests, too... A way reprogram that can be the rules

- a single statement is either empty (crac: issue "null;") or not;
- a statement-in-sequence is either empty (don't issue "null;" !) or not;
- a sequence is either empty (crac: issue "null;") or not;

... with the risk to confuse ayacc a bit more.
