You are correct as long as the program being called tries to use arguments
in the standard way [ main(argc, argv)].

However, if you can change the program being called, it is possible to get
the command line unparsed by DOS.  The length of the command line is stored
at PSP + 80, then usually followed by a space, then the command line as it
was entered.  Note that this is guaranteed only if the calling program sets
up the int 21h, function 4Bh in this way.  Command.com does, but some other
programs which start child processes may not.
