Without taking sides, this comment isn't relevant to Hoare's original complaint, which applied to C just as well as Ada. He wanted to prove program reliability. (However, as an aside on this topic, as an undergrad I had a classmate whose summer job was writing test cases for the Ada validation suite. She assured me [incorrectly] that it would be at least 10 years before anyone had an approved Ada compiler. Of course, I later did grad work at NYU, where I got to hobnob with the people who wrote that first compiler! ;-) Matthew > -----Original Message----- > From: Bullard, Claude L (Len) [mailto:clbullar@i...] > Sent: Monday, August 27, 2001 7:07 AM > To: Steven R.
