I see you are awake! Nice to hear from you! I thought that an operating system was supposed to handle the 'mundane' task of resource management, be it memory, tapes, disks, modems, printers, displays, or whatever we decided to hook up to it. IT is supposed to be able to STOP the overrunning of an application program into protected memory space or into another application. Kind of the KING controller! Is this about it? That being said, how do you stop the clever programmer that turns a 'data' file into a 'program' file by manipulation after the file is loaded. I used to call this 'in flight program modification' and it is not only really successful, but virtually impossible to trap, without running the program under and entirely different program that evaluates each instruction prior to 'feeding' it to the processor. When running in SP (Super Protect) mode, performance drops to about 20% of original throughput. Most computer users couldn't or wouldn't tolerate this type of system degredation. ( I know I wouldn't! ) If one knows how to crash a system, ( it ain't too hard! ) than it really is pretty easy to create 'bandit' code, if one is so inclined! I suspect that the operating system that you wrote in school was not subject to the attacks of some of the 'hackers' of today, or for that matter the handling of some of the 'poorly' coded applications of today! Any operating system runs fine in the 'idle loop'! Ken
