There is typeinfo in Delphi/fpc, but that is for RTTI, and quite different The above is a bit strange in Pascals with unit system, since it potentially creates a var of a type that might not be in the scope. So I think it is not even possible to implement this in a straight way. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
