http://cm.bell-labs.com/cm/cs/who/dmr/chist.html Deryk is mostly right. It *was* derived from B & BCPL. It was not *directly* created to rewrite Unix. KGT did realize very early, though, that Unix needed a system language, and thus he created B ("it is BCPL squeezed into 8K bytes of memory and filter- ed through Thompson's brain"). C was created to solve B's deficien- cies. Finally, "By early 1973, the essentials of modern C were complete. The language and compiler were strong enough to permit us to rewrite the Unix kernel for the PDP-11 in C during the summer of that year." -- ----------------------------------------------------------------- Ron Johnson, Jr. [EMAIL PROTECTED] Jefferson, LA USA "I'm not a vegetarian because I love animals, I'm a vegetarian because I hate vegetables!" unknown -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
