subcommand

    Specifies an operation you want PCSI to perform. If you do not
    supply a subcommand, the utility prompts you to select one from a
    list.

 product-name

    Specifies the name of the product to which you want to apply
    the activity. Some subcommands do not require this parameter.
    You can use the asterisk (*)  and the percent sign (%) wildcard
    characters for all or part of the product-name. You can specify a
    list of products separated by commas (,).

    The product name is the same as the third component of the
    file name of the product kit. For example, the product name
    parameter that you would use to refer to a kit named DEC-AXPVMS-
    FORTRAN-V0702-3-1.PCSI is FORTRAN. A product name can include an
    underscore character (_)  but never a hyphen (-). For example,
    VMS73_DRIVER is the name of a remedial kit for OpenVMS whose file
    name is DEC-AXPVMS-VMS73_DRIVER-V0300-4.PCSI.
