ABSTRACT:
An electronic apparatus which is capable of preventing loss of edited operation data even if a user fails to perform a saving operation on the edited operation data. A set of operation data is recalled from either the original storage or the shadow storage to the current storage. Changing of the contents of the operation data stored in the current storage is reflected in the contents of a corresponding set of operation data of the n sets of operation data stored in the shadow storage. When a set of the operation data stored in the current storage is saved, the saved set of operation data is written into a storage area of the original storage and a corresponding storage area of the shadow storage.
