FileRename
FileRename (Old,New)
Renames a file from old name to new. A file may be moved to a new
directory with this command. You can not use this command to move files
from one drive to another. FileRename will also fail if the source file
doesn't exist or the destination file does exist. FileResult can be
tested to make sure the rename executed correctly.
Example:
FileRename ('F:\HOME\MARC\MESSAGE.TXT','F:\HOME\GRACE\MESSAGE.TXT')
FileRename now supports long file names.
