1. BUG:

     In vfp9, usually the VERSION() function returns "Visual FoxPro 09.00.0000.7423 for Windows".

     In VFP Advanced, usually the VERSION() function returns "Visual FoxPro 10.00.0000.yymm for Windows".
     For backward compatibility, we can disable the VERSION() function returns the new version information,
     then the VERSION() function will return "Visual FoxPro 09.00.0000.7423 for Windows".


2. CAUSE:

     There are some BUGs in the following code.


3. RESOLUTION:

     We can write some code to fix the BUG.
