Not quite true.
    1. Bare PC-DOS (without COMMAND.COM) can load .COM programs via EXEC.
       That's how COMMAND.COM is probably loaded.
    2. Microsoft's MS-DOS Programmer's Reference Manual 3.1 states that
       only IBM's version (PC-DOS, not generic MS-DOS) has the .EXE loader
       in (the transient portion of) COMMAND.COM.  IBM wanted it that way to 
       save memory.
