It means you cannot do TSomeType(1):=SomethingElse as opposed to TSomeType(AVariable):=SomethingElse Which means essentially that a typecast of a constant is still a constant, and cannot be assigned to. (same goes for expressions) You can of course do SomethingElse:=TSomeType(1) Michael. _______________________________________________ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal
