/FORMAT=keyword

    Specifies the output format of the product kit. Keywords are:

    REFERENCE  Reference format in which product files are placed
               in a directory tree for direct access. The utility
               creates a product description file, with a file
               type of .PCSI$DESCRIPTION, in the top level of the
               directory tree.

    SEQUENTIAL Sequential format in which product files are placed in
               a container file having a .PCSI file type.

    The default is /FORMAT=REFERENCE.

    You cannot use the PRODUCT PACKAGE command to create a kit in
    compressed format. Instead, use the PRODUCT COPY command to
    convert a kit in sequential format to a kit in compressed format.
