   FUNCTION
        This function returns a pointer to the last component of a string path

        path - pointer to an path string.  May be relative to the current
               directory or the current disk.

   RESULT
        fileptr - pointer to the last component of the path.

   EXAMPLE
        FilePart("xxx:yyy/zzz/qqq") would return a pointer to the first 'q'.
        FilePart("xxx:yyy") would return a pointer to the first 'y').
