FIXFILE will update the structure of your data files.  In order to do so, it 
needs the corresponding .TXT file, which has the same name as the data file
but with the extension .TXT.  If the old structure matches the new TXT file, 
then nothing happens.  If there is a difference, then the old file is saved 
with the same name, but with a .FIX extension, the database file is rebuilt,
and the original data is copied into it.

If the data file does not exist, or is damaged, and there is a .TXT file, then
executing FILEFIX CREATE [filename] will recreate the empty data file.  The
original file must first be deleted.

If there is a problem with a DBT file (eg: CLIENT.DBT), then the DBT file must
be recreated.  The original DBT file will be destroyed.  The DBT file contains
memo information.  Copy the DBF file (eg CLIENT.DBF) to another area.  Execute
FIXFILE CLIENT CREATE.  This will create a new, empty CLIENT.DBF and a new,
empty CLIENT.DBT. Then copy the original, saved CLIENT.DBF back.  Then execute
FIXFILE CLIENT again to update the CLIENT.DBF.

The file DBTXT???.EXE contains the database TXT files.  The last 3 characters 
of the file name indicate the DRDINING version.  Make sure that the TXT files 
match the version of DRDINING.EXE you are using.  Older database structures 
may not be compatible with the new DRDINING.EXE versions.  Check the DBTXT???
file date also, to make sure you are using the latest version.

DRUTILS.EXE contains the DBTXT???.EXE file and FIXFILE.EXE.
