I stand corrected. I've just checked Delphi5 and indeed it allows a direct typecast from ansistring to any object/class :-/ But Delphi also allows direct cast from enumeration value to pointer (which FPC doesn't allow), so maybe this is another nice oportunity to be stricter than Delphi ;-)

Using the "as" operator is. var p: pointer; i: integer; begin i := 10; p := TObject(i); //will work, but is invalid p := (i as TObject); //should fail (not tried) because i is not compatible end; M _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
