     FILEDELETE() returns .T. when at least one or more files are deleted;
     otherwise, .F. is returned.

 Description

     Occasionally, you will need to clean up a floppy or a hard disk or
     delete whole file groups.  This function deletes entire file groups with
     a function call, without using the RUN command.

 Notes

     Warning!  FILEDELETE() can also delete system files.

     .  The default standard attribute is archive (32).  Drive and
        path designations, and wildcards are permitted.

     .  Subdirectories must be deleted with the help of the
        DIRREMOVE() function.

 Example

     Attempt to delete all index files, then display the completion status:

     IF FILEDELETE("*.NDX")
        ? "Files deleted."
     ELSE
        ? "No files found."
     ENDIF
