I can think of plenty of > examples on other systems and hardware. I didn't intend to imply that it was new; just the opposite. When hardware manufacturing and software development for that hardware became corporately separated, the software developers used "short cuts" to get into the guts of the machine even when they were doing app-level development. That's why Msoft's so-called OSes were so insecure and buggy. Not even Cutler could make them honor the wall that should have been between the exec code and a mere user. /BAH
