Looking at the MSDOS and MSWORD source code some 50 years later
Looking at this source, looks fine to me. Lot of comments, maybe added later. msword seems to have 200 files, 180,000 lines Looks well written, a lot of comments. I think everyline is almost commented actually 31 ASM (assembly files), comments might have been added later? 24 C files https://www.gatesnotes.com/meet-bill/meet-bill-home-topic/reader/my-first-memoir-source-code https://github.com/michaelmsonne/MS-WORD https://github.com/microsoft/MS-DOS/tree/main/v4.0
