                      [NEW.....] VFP 9.0 FIX - THE INDEXADD TERM IN THE CONFIGURATION FILE
                                January 2024

1. THE INDEXADD TERM:

     INDEXADD - Specifies the additional name for Visual FoxPro index files

     Specifies the additional name for Visual FoxPro index files.

     INDEXADD = additionalname

     Parameters
     additionalname
     Specifies the additional name (1-15 characters) for Visual FoxPro index files.
     The default setting is "_index".

     Remarks
     If we enable opening nonstructural compound index files with the table automatically in Visual FoxPro Advanced,
     it will open nonstructural compound index files (tablefilename+additionalname+"*.cdx") with the table automatically.
     If we enable opening standalone index files with the table automatically in Visual FoxPro Advanced,
     it will open standalone index files (tablefilename+additionalname+"*.idx") with the table automatically.


2. CAUSE:

     There are some BUGs in the following code.


3. RESOLUTION:

     We can write some code to fix the BUG.
