HELP is available for the following Oracle Rdb CHANGE statements:

    o  CHANGE DATABASE

    o  CHANGE FIELD

    o  CHANGE INDEX

    o  CHANGE PROTECTION

    o  CHANGE RELATION

    o  CHANGE STORAGE MAP

    However, to get HELP on any of these CHANGE statements at the
    "Topic?" prompt, include an underscore between CHANGE and the
    item on which you want information displayed. For example, to get
    HELP on the CHANGE FIELD statement, type either of the following:

    Topic?  CHANGE_FIELD
    RDO>  HELP CHANGE_FIELD
