/sys$common/syshlp/helplib.hlb LICENSE, DISABLE, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    LICENSE DISABLE does not immediately affect loaded licenses. To
    affect a loaded license, you must first enter a LICENSE UNLOAD
    command, which unloads the license, but allows current processes
    to finish using the product. Note that to immediately disable all
    loaded licences, you must shut down the system.

    You cannot use LICENSE LOAD to activate a disabled license; you
    must first use LICENSE ENABLE.

    LMF does not display error messages when either you or the system
    attempts to unload a disabled license.
