It&#x27;s not untrue, but it&#x27;s worth remembering that programming computers in assembly language was quite popular at that time, especially for systems software. Assembly has idioms that can be many lines long, and you tend to recognize them after you&#x27;ve programmed a system for long enough. 10 pages of uncommented, but idiomatic assembly code are more or less the equivalent of 2-3 pages of uncommented (but often idiomatic) C code, which can be fairly manageable.
