                        VFP 9.0 FIX - COPY FILE COMMAND

1. BUG:

     In vfp9 (and vfp6, vfp7, vfp8), the COPY FILE command always creates the destination file with a lower case file name.

     In Windows operating system, we can use the file names with not case-sensitive,
     for example, the file name ABC.TXT is the same as the file name abc.txt.
     In other operating systems such as Unix and Linux, we use the file names with case-sensitive,
     for example, the file name ABC.TXT is not the same as the file name abc.txt, they are two different file names.

     The bug was reported by Walther Neuhardt.


2. CAUSE:

     There are some BUGs in the following code.


3. RESOLUTION:

     We can write some code to fix the BUG.
