Debug_Options={options}

    The Debug_Options qualifier allows you to turn on certain debug
    functions. The Debug_Options qualifier accepts the following
    options:

    o  [NO]TRACE

       Traces the qualifier and parameter processing performed by
       RMU Unload. In addition, the query executed to read the table
       data is annotated with the TRACE statement at each Commit
       (controlled by Commit_Every qualifier). When the logical name
       RDMS$SET_FLAGS is defined as "TRACE", then a line similar to
       the following is output after each commit is performed.

       ~Xt: 2009-04-23 15:16:16.95: Commit executed.

       The default is NOTRACE.

       $RMU/UNLOAD/REC=(FILE=WS,FORMAT=CONTROL) SQL$DATABASE WORK_STATUS WS/DEBUG=TRACE
       Debug = TRACE
       * Synonyms are not enabled
       Row_Count = 500
       Message buffer: Len: 13524
       Message buffer: Sze: 27, Cnt: 500, Use: 4 Flg: 00000000
       %RMU-I-DATRECUNL,   3 data records unloaded.

    o  [NO]FILENAME_ONLY

       When the qualifier Record_Definition=Format:CONTROL is used,
       the name of the created unload file is written to the control
       file (.CTL). When the keyword FILENAME_ONLY is specified, RMU
       Unload will prune the output file specification to show only
       the file name and type. The default is NOFILENAME_ONLY.

       )
       %RMU-I-DATRECUNL,   3 data records unloaded.

    o  [NO]HEADER

       This keyword controls the output of the header in the control
       file. To suppress the header use NOHEADER. The default is
       HEADER.

    o  APPEND, INSERT, REPLACE, TRUNCATE

       These keywords control the text that is output prior to the
       INTO TABLE clause in the control file. The default is APPEND,
       and only one of these options can be specified.
