Second of all, you don't seem to understand the point. If GNAT or any other program, malfunctions, that is one thing. If it takes the operating system down with it, that is QUITE another thing. It is the latter behavior that you seem to find quite reasonable in the Windows environment from your previous posts, but the point is that in a decent operating system, bad applications software can NEVER disable the operating system. For example in OS/2, it is extremely rare to see the system freeze up or crash. I can only remember one instance recently in which OS/2 froze on me, and it could well have been a hardware problem, since the machine I am working on is old and tired. By the way, when OS/2 did freeze in this instance, I lost only two keystrokes of the file I had been editing, everything else was saved automatically. The technology for essentialy crash-proof operating systems has been around for decades, it just has not arrived in Redmond yet! Sent via Deja.com http://www.deja.com/ Before you buy.
