Displays a list of software products installed on your system.
    Use the /FULL qualifier to display additional information such as
    kit type, maintenance activity, and software dependencies.

    Format

      PRODUCT SHOW PRODUCT  product-name[,...] [/qualifiers]

1  –  Parameter

 product-name

    Names the product or list of products to include in the display.
    This is an optional parameter. If you omit it, the names of all
    installed products will be shown.

2  –  Qualifiers

2.1    /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.

2.2    /FULL

       /FULL
       /NOFULL (default)

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

2.3    /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

2.4    /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.

2.5    /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=*

2.6    /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.]

2.7    /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.

2.8    /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.

3  –  Example

  $ PRODUCT SHOW PRODUCT * /REFERENCED_BY=DECNET_OSI

      The command in this example lists all products on which the
      DECnet-Plus product is dependent.
