`case' statments: `default' and `others' - Gpc

15 Nov 1997


      Hello, everybody!
I am currently fixing the bug with `otherwise' in `case'
statements.  While the ISO 10206 Extended Pascal standard wants
case foo of                      (* 1 *)
      bar: writeln ( 'foobar!' );
    otherwise
      write ( 'The answer is: ' );
      writeln ( answer );
    end (* case *);
GPC implemented
case foo of                      (* 2 *)
      bar: writeln ( 'foobar!' );
    otherwise:
      begin
        write ( 'The answer is: ' );
        writeln ( answer );
      end (* otherwise *);
    end (* case *);
which is simply wrong.  Okay - when I fix it, does anybody want
to keep an optional colon after `otherwise'?  Or after `else'
in the Borland syntax?  (I would prefer if *not*.)
I also found `default' and `others' as synonyms for `otherwise'
which I would like to remove.  May I?  Or are they needed for
compatibility with some Pascal compiler I am not aware of?
If so, what is the syntax?  Example 1 or 2 above?
While I am on it, what about removing `&' as an address operator
and to keep only the BP-compatible `@'?
Please post your opinions here.
Thanks,
Peter
