VMS Help MESSAGE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Message utility (MESSAGE) lets you supplement system messages
    with your own messages. Your messages can indicate that an error
    has occurred, or they can indicate other conditions; for example,
    that a routine has run successfully or that a default value has
    been assigned.
