1    /ALL

    Uninstalls all patch and mandatory updates for which recovery
    data has been saved. Once the operation completes, all the
    recovery data sets are deleted and cannot be reused. If you do
    not specify the /ALL, /NEWEST, or /SINCE qualifier, only the most
    recently created recovery data set is used to select patches and
    mandatory updates to remove.

2    /LOG

       /LOG
       /NOLOG (default)

    Displays the file specifications of files as they are accessed;
    also provides other information related to file activity. For
    example, when logging is enabled, messages notify you when
    product files, libraries, directories, and product database files
    are created, deleted, or modified.

3    /NEWEST

       /NEWEST=count

    Selects the most recently created patch recovery data sets. For
    example, if you specify /NEWEST=3, the PRODUCT UNDO PATCH command
    uninstalls patches using data from the three newest recovery data
    sets. If you do not specify a number with this qualifier, the
    default value is 1.

4    /OPTIONS

       /OPTIONS=keyword
       /NOOPTIONS (default)

    Specifies PRODUCT command options. The keyword is:

    NOCONFIRM        Omits the confirmation dialog that asks the user
                     to verify the recovery data sets that have been
                     selected for processing.

5    /REMOTE

       /REMOTE
       /NOREMOTE (default)

    Selects recovery data sets located on a privately mounted system
    disk and restores the product database to this disk. By default,
    PCSI searches the currently booted system disk for recovery data
    sets.

    When you use /REMOTE, the following logical names must be
    defined:

    o  PCSI$SYSDEVICE must specify the physical disk name of the
       target system disk. This disk must be mounted and allocated to
       the process executing the PRODUCT command.

    o  PCSI$SPECIFIC must point to a system root on PCSI$SYSDEVICE.
       It must be defined in the following form, where x is a valid
       system root:

       PCSI$SYSDEVICE:[SYSx.]

6    /SINCE

       /SINCE=time

    Selects recovery data sets that were created on or after the
    specified date and time. You can specify time as an absolute
    time, as a combination of absolute and delta times, or as one of
    the following keywords:

       TODAY (default)
       YESTERDAY

    For information about specifying time values, see the OpenVMS
    User's Manual.

7    /TRACE

       /TRACE
       /NOTRACE (default)

    Identifies the creation and deletion of subprocesses and the DCL
    commands and command procedures submitted to these subprocesses
    for execution during the processing of the PRODUCT command.
    Messages log the creation and deletion of scratch directories and
    temporary files that the PCSI utility provides for the subprocess
    environment. Any output that DCL produces is also displayed.

    This qualifier is primarily a debugging aid for product
    developers to trace the execution of command procedures included
    in their product kits. See the POLYCENTER Software Installation
    Utility Developer's Guide for more information.
