rse                    A record selection expression. A phrase
                           that defines specific conditions that
                           individual records must meet before
                           Oracle Rdb includes them in a record stream.

    on-error               The ON ERROR clause. Specifies host
                           language statement(s) to be performed
                           if an error occurs during the FOR loop.
                           For more information see the entry on ON
                           ERROR.

    statement              Any valid RDML or host language statement
                           to be executed within the FOR loop. Use
                           a semicolon (;) at the end of each RDML,
                           Pascal, or C statement.

    handle-options         A request handle, a transaction handle, or
                           both.

    REQUEST_HANDLE var     The REQUEST_HANDLE keyword followed by a
                           host language variable. A request handle
                           identifies a compiled Oracle Rdb request.
                           If you do not supply a request handle
                           explicitly, RDML associates a unique
                           request handle for the compiled request.

    TRANSACTION_HANDLE     The TRANSACTION_HANDLE keyword followed by
    var                    a host language variable. A transaction
                           handle identifies a transaction. If
                           you do not supply a transaction handle
                           explicitly, RDML uses the default
                           transaction handle.
