When one or more Oracle Rdb multiversion kits are installed on
    your system, you can read the DCL help topics that were written
    for each multiversion kit.

    Suffixes are added to DCL help topics when multiversion kits for
    one or more versions of Oracle Rdb are installed on a system.
    These suffixes are numbers that identify the topic as being
    written for a particular version of Oracle Rdb.

    To read the DCL help topics that were written for the
    multiversion kit for a particular version of Oracle Rdb, you
    must:

    1. Set your default environment to the multiversion kit for the
       version of Oracle Rdb that you want help on. For example:

       $ @SYS$LIBRARY:RDB$SETVER 7.1

       This step is optional if you are already in the default
       environment for the multiversion kit for the version of Oracle
       Rdb for which you want help.

    2. Type HELP and the name of the topic you want help on. For
       example, to read the DCL help topics for the Oracle Rdb V7.1
       multiversion kit, type the following:

       $ HELP SQL72

       $ HELP RMU72

       $ HELP RDBPRE72

       $ HELP RDO72

       $ HELP RDML72
