Ed, you're either not listening, have just crawled out from under a rock, or are being obstinate. Didn't you hear? Linux is an Open Source operating system! Please stop trying to paint it with 50 years of IBM mainframe operating system history. As an open source effort, it is developed with open source tools. To wit, the GNU C/C++ compiler (gcc). Yes, you can write an operating system, including device drivers, in C. If MVS were being written anew today, much of it would be in C. To the extent that machine-level instructions are present in open code (similar to PL/X GENERATE), they are there because they are doing things that the compiler cannot do. This is true on ANY operating system written in ANY language; there are times when only machine language (platform assembler) will do. And before you ask, the assembler in Linux is open source, too.. What is it? You may have guessed: the GNU Assembler (gas). >Its typical of people like you to end the discussion with an ignore. >I tend to read everybody's opinion then form a judgement but with the >new generation if you don't want to hear you just turn them off. >Thats up to you but you are destined to not understand someone else's >opinion by doing so.

You have made yet another uninformed judgement. :-( I get the impression that you have an internal picture of the universe that is colored just so, oriented just so, shaded just so, and are not of a mind to perceive the universe anew when presented with new information, or to accept that there are other pictures that are just as valid as your own.
