摘要

The method involves acquiring statistical data related to a program unit (15), with help of a diagnostic unit (16) in a portable data medium. The diagnostic unit is implemented as a component of the program unit for acquiring the statistical data. The statistical data is stored in a statistical data unit (17), which is arranged in a memory (12) of the data medium and assigned to the diagnostic unit. An independent claim is also included for a system with the portable data medium.
