Hi,
TRUNCATE TABLE is not a PL/SQL command; it's a SQL command.
To run a purely SQL command in PL/SQL, use EXECUTE IMMEDIATE.
SET AUTOTRACE isn't a PL/SQL command either; it's a SQL*Plus command, and I don't know of any way to run it except from the SQL*Plus command prompt.
I think this is what you need to do:
SET AUTOTRACE ON;
declare
  -- Local variables here
  i integer;
begin
  -- Test statements here
    EXECUTE IMMEDIATE 'truncate  table plan_table';
end;
