IBM PC-DOS or Micro$oft MS-DOS? I have the PC-DOS 3.20 manual.

I believe DOS 3.20 is what I was looking for.  It came as original
software
for a Packard Bell 386/12T (don't remember the specific model name), and
I
used the accompanying book to teach myself DOS programming -- back in
1991...   The system had dual floppies (both sizes), a small hard drive,
no
sound except for the system speaker, and one of the first mass
production
.25 dpi monitors.  I paid through the nose for the system at the time,
but
I'd likely give an arm and a leg for that old DOS manual...
Cheers!
Ed

 There ain't no sech thing as 2.3

 3.20 (internally it thinks that it is three point twenty, NOT two), is the

without special machine

  specific modifications.
 2.11 and 3.31 are only available in versions that were intended for
 specific machines.  'Course in most cases, the only thing that is
 different is the code in MODE.COM, and sometimes FORMAT.
 If you have a machine with specific peculiarities, 3.31 is the hot setup.
