OS's provide services. Programmers want to use those services. Ada seems to be insisting "No, I won't let you use this one because it isn't safe, but if you want to do it behind my back, call this C function when I'm not looking..." Every so often, I like to run with scissors just because I'm a grownup and can do it now without getting yelled at. :-) MDC Robert I.
