The DCL command SHOW LICENSE displays software product licenses
    active on the current node. An active license is one that has
    been registered in the LICENSE database and has been loaded
    into system memory. To register and activate software product
    licenses, use the License Management utility (LICENSE) or
    VMSLICENSE.COM. Some licenses are registered automatically during
    product installation.

    To display licenses registered in the LICENSE database, use the
    LICENSE LIST command.
