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.
