Syntax options:

    FORWARD_REFERENCES | NO FORWARD_REFERENCES

    The EXPORT statement analyzes all dependencies in the database
    to determine which functions and procedures are referenced by
    other definitions. Since IMPORT defines each object type in a
    strict order, it is possible that some definitions may be used
    prior to their definition. For instance, tables are defined
    before modules, but the table might call an SQL function from
    a module. The FORWARD_REFERENCES option requests that EXPORT
    save descriptions of these routines first in the interchange file
    so that IMPORT can declare them prior to their usage. See the
    DECLARE Routine statement for more details.

    FORWARD_REFERENCES is the default. If the interchange file is
    to be used by a version prior to Oracle Rdb V7.1.0.4 then the
    NO FORWARD_REFERENCES option should be used to exclude this
    information.
