The DOS memory management was probably written sometime around summer 1982, and it meshed with the newly added process management functions (EXEC/EXIT/WAIT)—allocated memory is owned by the current process, and gets freed when that process terminates. Note that some versions of the memory manager source code (ALLOC.ASM) include a comment that says ‘Created: ARR 30 March 1983’. That cannot possibly be true because by the end of March 1983, PC DOS 2.0 was already released, and included the memory management support. The DOS 2.0 memory management functions were already documented in the PC DOS 2.0 manual dated January 1983.
I've thrived on hands-on and the confidence I had after trying to break things. Breaking these would be way above my pay grade, so you'd have to use blind faith. That turns to cause bigger messes, not guarantee fewer.
