This code was likely written on a Macintosh Plus with a 9 in (23 cm) monochrome display that had a resolution of 512 × 342. Something to keep in mind. That's very little screen real estate (tiny!) and something that had to be respected. Writing long winded stuff had a cost in performance and maintainability. We sometimes wrote the documentation separately when needed. Sometimes that was printed out for ease of consumption. Then we have the issue that the Mac had only just been upgraded to 1MB of memory (4MB potentially) and only 800 KB floppy drive. And an 8 mhz processor.
