    There is three tricks to do this under DOS 3.3. The first is to print the
command just like in AppleSoft. Remember though, the [Control-D] must be the
first character printed after a [Return], else DOS 3.3 will not detect it.

    The second is to get the book 'Beneath Apple DOS'. This book tells you 
how DOS 3.3 is broken down into 3 parts, the command processor, the file
manager, and the rwts handler. You could make direct file manager calls if
you studied the book long enough.

    Third, use DOS 3.3's rwts (read/write-track/sector) and do all the file
management yourself.

Its up to you, but get the book.
