       /ISSUER=string

    Positional qualifier.

    Specifies the name of the company (for example, DEC) that issued
    the PAK for the product. Use this optional qualifier only if you
    need it to identify the license. This qualifier affects only the
    product name that immediately precedes it in the command string.
