In PC DOS 2.0, three memory management functions were introduced: ALLOC (48h), DEALLOC (49h), and SETBLOCK (4Ah). The DEALLOC function may be better known as “free” and SETBLOCK as “resize”. The all-caps names are used in the actual DOS source code.

My goal with agentic coding is always the same. I want to understand the structure of what I’m building well enough that I can open any file and immediately see why it exists and how it fits into the system.
The owner of a memory block is a 16-bit word. It is set to zero to indicate a free block. A non-zero value is normally the PID (process identifier) of the owner, that is, the address of the PSP of the owning process. This is important when a process terminates, because DOS automatically frees all memory blocks that the process owned. Note that DOS performs no validity checks on the owner; any process can free or resize any block, regardless of who owns it, and the MCB owner need not be a valid PID.。体育直播对此有专业解读
