Chapter 4 55
Remember that only one file can be open at any given time so
whenever a new file is created, if a file was already open, the file that
was open will be closed. Once a file has been closed, it cannot be
reopened and new values can no longer be stored. In closed files,
values can only be viewed.
Whenever you create a new file, and another file is already open, a
warning screen will ask if you want to close the last file.
Touch
to confirm that you want to close
the open file to create (open) a new one or
touch
to cancel and return to the menu.
