DESCRIPTION
       IBM Personal Computer DOS Version 3.2 provides required
support for an application program to interface with IBM Personal
Computer hardware. It supports all members of the IBM Personal
Computer family. DOS allows the user to manage files on a disk or
diskette (display directories, rename files, copy files, and so on).
DOS also provides the ability to start an application consisting of
one or more programs linked together into a single load module.
       DOS 3.2 includes a BASIC Language Interpreter Version 3.2
which is described in the separately available BASIC Reference
Version 3.2 (6280075).
       DOS Version 3.2 also provides a line editor and debug utility
programs to aid in program development. A linker program is provided
to convert language compiler relocatable modules to executable load
modules.
       An enhanced screen dump utility program that supports the IBM
PC Convertible Liquid Crystal Display and IBM PC Convertible Printer
is also provided.
       New commands are provided to support copying of files in more
than one subdirectory, and to allow referral of a physical device as
multiple drive letters.
SCHEDULE
       Manual updates are planned to be available in second quarter
1986.

COMPATIBILITY: IBM Personal Computer DOS Version 3.2 is an upwardly
compatible enhancement to DOS 3.1 and contains maintenance updates to
DOS 3.1.  DOS 3.1 is still available. DOS 3.2 provides support for
the IBM PC Convertible, 3.5-inch diskette, and IBM Token-Ring
Network. Because the storage requirements are 8Kb greater than DOS
3.1 (44Kb versus 36Kb), some programs may not fit in the same size
machine. In such instances, a program may be divided into smaller
segments, or more memory may be added to the system  unit.
o   3.5-inch diskette drive support: Provides full support for 720Kb
    3.5-inch diskette drives, including the normal DOS commands for
    managing and using diskettes as well as for defining a physical
    device as two logical devices.
o   IBM PC Convertible support:
    -   System wait is a BIOS function provided to conserve battery
        power on the IBM PC Convertible. It is invoked when a long
        external event delay, such as waiting for a keystroke, is
        taking place.
    -   Diskette change line support is provided for the IBM PC
        Convertible.  This function detects that a diskette door has
        been opened, and that the diskette may have been changed.
    -   The GRAPHICS program has been enhanced to support the IBM PC
        Convertible Liquid Crystal Display and the IBM PC Convertible
        Printer.
o   DOS environment area can now be reserved:  A new option of the
    SHELL command allows this area to be expanded to 32Kb.  This
    allows the user to specify more extensive PATH commands, PROMPT
    commands, and SET commands without running out of environment
    space.
o   FORMAT:  The FORMAT Command now requires the user to specify the
    drive letter; it no longer uses the current drive as the default.
    When formatting a fixed disk, the FORMAT command requires the
    user to specify the Volume ID of the disk. A warning message is
    also displayed, indicating that all data on the fixed disk will
    be lost if the user chooses to proceed with the formatting.
o   REPLACE:  A new command, REPLACE, is provided to replace all
    occurrences of a file on a disk.
o   SELECT:  The SELECT command has been enhanced to provide
    additional flexibility.
o   XCOPY:  A new command, XCOPY, has been added to allow the user to
    copy files in more than one subdirectory. Options allow prompting
    for selective copying of files, verify after write, copying of
    lower level directories even when empty, copying of files
    modified after a specified date, and copying of archived files
    only (with or without modifying the archive bit).  XCOPY can be
    performed where the source and target drives are of different

    densities.
o   Utilization of the BIOS parameter block:  The BIOS parameter
    block is used to obtain media-type information to remove
    dependence on the File Allocation Table ID for the media-type
    information.
o   I/O control subfunctions:  DOS 3.2 implements subfunctions that
    enhance device independence. These subfunctions allow querying
    and changing of device parameters as well as logical device
    support. These subfunctions are:
    -   Get device parameters
    -   Set device parameters
    -   Read track on logical drive
    -   Write track on logical drive
    -   Format and verify track on logical drive
    -   Verify track on logical drive
    -   Get logical device number (determine if a device has more
        than one letter)
    -   Set logical device number (suppress diskette change request
        messages)
       IBM Personal Computer DOS 3.2 is an upwardly compatible
enhancement to DOS 2.1 and contains maintenance updates to DOS 2.1.
DOS 3.2 requires a minimum of 44Kb of user memory. (DOS 2.1 requires
24Kb.) Because DOS 3.2 storage is 20Kb greater, some programs may not
fit in the same size machine. In these cases, a program may be
divided into smaller segments, or more memory may be added to the
system unit. In addition to those described above, DOS 3.2 contains
the following enhancements:
o   Optional file sharing: Applies on a file basis; provides full
    range of sharing possibilities.
o   Block locking: Provides the ability to restrict access to all or
    part of a file when the file is opened in a shared mode.
o   Support for IBM PC Network/IBM Token-Ring Network:  Allows
    addition of the IBM PC Network programs. These programs are
    available separately and require appropriate network hardware.
o   Background print: Modified version of DOS 2.1 Print, which now
    supports path specifications and an internal programming
    interface.
o   Additional interrupt 21H functions: Additional function calls
    provide enhanced file management and support for the IBM PC
    Network environment.
o   Enhanced error recovery: Additional error reporting facilities to
    enhance support in the IBM PC Network environment.
o   Support for IBM Personal Computer AT: 1.2Mb diskette drives,
    non-volatile timer, larger fixed disk size (20Mb versus 10Mb for
    DOS 2.1).
o   BASIC Interpreter: Supports IBM Personal Computer Enhanced
    Graphics Adapter, IBM PC Convertible, IBM PC Network, IBM
    Token-Ring Network, and DOS Extended Error facilities. BASIC
    Reference Version 3.2 contains a more detailed description of the
    changes.
o   VDISK: RAM disk. Allows use of part of storage for a virtual
    disk; supports extended memory (above 1Mb) on IBM Personal
    Computer AT for virtual disk.
o   Large linker: Supports up to 1Mb
o   SUBST: Substitute string.
o   JOIN: Splicing of directories.
APPLICATION PROGRAMS: The following licensed programs have been
tested for compatibility with DOS 3.2 and operate as described in
their program documentation:
