The the nested procedure is only valid when called from the parent procedure. TList.Sort() is a different procedure that does not know if a giving procedure is a nested procedure or not. The correct fix for the compiler is to give an error. Relying on the behaviour of calling conventions is very bad. Also the code won't work on sparc/ppc which have a different calling convention. _______________________________________________ fpc-devel maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-devel
