1    /BASE_SYSTEM

       /BASE_SYSTEM=(base-system-name[,...])

    Selects software products whose base system matches the one
    specified. The base system name identifies both a hardware
    platform and an operating system. Standard names are:

    Name          Description

    AXPVMS        Denotes an OpenVMS Alpha product.
    I64VMS        Denotes an OpenVMS I64 product.
    VAXVMS        Denotes an OpenVMS VAX product.
    VMS           Indicates a product that can be installed on more
                  than one OpenVMS platform.

    Parentheses (())  are optional only when you specify a single
    base system name. They are required when you specify multiple
    base system names.

2    /FULL

       /FULL
       /NOFULL (default)

    Displays information in 132-column format. The /NOFULL qualifier
    displays a subset of available information in 80-column format.

3    /MAINTENANCE

       /MAINTENANCE=(product-name[,...])

    Displays the products to which the named maintenance products
    have been applied. A maintenance product is either a patch kit or
    a mandatory update kit.

    Parentheses (())  are optional only when you specify a single
    product name. They are required when you specify multiple product
    names.

    To list all maintenance products that have been applied to a
    particular product, use the following command:

    PRODUCT SHOW PRODUCT product-name /FULL

4    /PRODUCER

       /PRODUCER=(producer-name[,...])

    Selects software products that the specified manufacturer
    produces.

    Parentheses (())  are optional only when you specify a single
    producer name. They are required when you specify multiple
    producer names.

5    /REFERENCED_BY

       /REFERENCED_BY=(product-name[,...])

    Displays products that are referenced by the named product.
    Use this qualifier to show if the product, specified in the
    /REFERENCED_BY qualifier, has a software dependency on the
    product or products specified in the product-name parameter of
    the SHOW PRODUCT command. If you specify an asterisk (*)  as the
    product name, all referenced products are listed for the product
    named in the /REFERENCED_BY qualifier.

    Parentheses (())  are optional only when you specify a single
    product name. They are required when you specify multiple product
    names.

    To list all products that require a specified product to be
    installed, use the command:

    PRODUCT SHOW PRODUCT product-name /FULL /REFERENCED_BY=*

    To list all products that are referenced by (that is, required
    by) a particular product, use the command:

    PRODUCT SHOW PRODUCT * /REFERENCED_BY=product-name

    To list all products that are referenced by (that is, required
    by) other products, use the command:

    PRODUCT SHOW PRODUCT * /REFERENCED_BY=*

6    /REMOTE

       /REMOTE
       /NOREMOTE (default)

    Selects the product database located on a privately mounted
    system disk. By default, PCSI searches the currently booted
    system disk for the product database.

    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.]

7    /SPAN_VERSIONS

       /SPAN_VERSIONS=keyword([,...])

    Selects software products whose versions match the specified
    version criteria. The keywords are:

    ABOVE=version    Selects versions greater than the version
                     specified

    BELOW=version    Selects versions less than the version specified

    MINIMUM=version  Selects versions greater than or equal to the
                     version specified

    MAXIMUM=version  Selects versions less than or equal to the
                     version specified

    The ABOVE, BELOW, MINIMUM, and MAXIMUM keywords can be
    used alone or in combination. For example, /SPAN_VERSIONS=
    (MINIMUM=V2.1,BELOW=V3.0) selects versions greater than or equal
    to V2.1 and less than (but not including) V3.0. Using the MAXIMUM
    keyword instead of BELOW would select versions that include V3.0.

8    /VERSION

       /VERSION=(version-number[,...])

    Selects software products that have the specified version.

    Parentheses (())  are optional only when you specify one version
    number. They are required when you specify more than one version
    number.
