The Examiner, by default, doesn't know the values of Natural'First and Natural'Last, since these are implementation-defined. You can supply these values with a configuration file - see the Examiner User Manual. Run the Examiner with the -conf switch to re-generate the VCs, then re-simplify. I then get 100% of the VCs proved. - Rod Chapman, SPARK Team PS...we now always recommend the use of -vcg not -rtc to generate VCs now.
