PCSI creates, installs, and manages software products. You can
    use it to do the following:

    o  Install and reconfigure software products.

    o  Remove software products.

    o  Display information from the software product database, such
       as the names of installed products, the names of patches
       applied, product dependencies, the names of files provided
       by product, and historical information about past operations.

    o  Locate software product kits.

    o  Create a software product kit in sequential, compressed, or
       reference format.

    o  List the contents of a software product kit or extract files
       from the kit, such as release notes or files you specify.

    o  Perform other operations such as establishing default
       configuration choices offered by a product, copying a product
       kit or converting it to a different format, and registering
       information about a product in the product database.

    o  Uninstall the last patch or set of patches applied to a
       product.

    To use PCSI from the DCL prompt, enter the PRODUCT command, a
    subcommand, and any required parameters and optional qualifiers.
    For example:

      $ PRODUCT INSTALL FORTRAN /VERSION=V7.2-3 /SOURCE=DISK1:[KITS]

    This command installs FORTRAN V7.2-3 on your system from a
    product kit located in DISK1:[KITS].
