       /PRODUCER=string

    Positional qualifier.

    Specifies the name of the company (for example, DEC) that owns
    the product for which you have a license. The default string
    for this qualifier is DEC. If DEC is not the producer of the
    product, you must use this qualifier to identify the product.
    This qualifier affects only the product name that immediately
    precedes it in the command string. Wildcard characters are not
    allowed.
