INT 2E - DOS 2+ internal - EXECUTE COMMAND
        DS:SI -> counted CR-terminated command string
Notes:  the top-level command.com executes the command
        results are unpredictable if invoked by a program run from a batch file
        all registers including SS and SP are destroyed as in INT 21/AH=4Bh
        Since COMMAND.COM processes the string as if typed from the keyboard,
          the transient portion needs to be present, and the calling program
          must ensure that sufficient memory to load the transient portion can
          be allocated by DOS if necessary.
        hooked but ignored by 4DOS v3.0 COMMAND.COM replacement
