Mr Mills is of the school that says "the design predicts that the program behaves like that, and the implementation has not changed for 10 years, so it must be correct". While I normally adhere to the same principles, it happened just a week or two ago that he had to admit that there was a bug in code that he firmly believed was correct and that an observed behaviour "could not possibly happen". So I agree with you that it never hurts to test something that theory has already proved to be correct. Maybe the actually released program does not really implement the mechanism that was designed, without the programmer knowing it. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
