Abstract

The invention relates to a method for controlling commands in several application files, whereby an access condition corresponding to said command is associated with each command in each application file, each command in each application file is executed if a user orders the execution thereof and if the access condition corresponding to said command is stored. According to the invention, the access conditions are stored jointly for all application files.

Description

technical field [0001] The present invention relates to a method for managing commands in multiple application files and a microchip card suitable for managing commands in multiple application files. [0002] The currently existing methods for managing commands are suitable for managing commands in multiple application files. For example, the method is applied to management commands such as creating, opening or deleting a sub-file in a first file related to a first application, or creating, opening or deleting a sub-file in a second file related to a second application. A device that executes these methods is called an "operating system". [0003] If the user expects the command to perform the operation, the access conditions associated with the command in the application file must be met. Background technique [0004] These access conditions have been standardized in common application files. Thus, for example, there is already the EN 726-3 stan...
