Abstract
A chip card has a program execution unit and a memory for at least one program that can be reloaded as a function of the application. In every reloadable program, first command instructions having absolute address parameters that refer to memory areas not occupied by the reloadable program are separated from second command instructions having absolute address parameters that refer to the memory area occupied by the reloadable program. It is possible for the reloadable program to be reloaded as a function of the application at any desired start address in the memory and to be adapted to that start address by the program execution unit. In particular, the need to create different reloadable program versions for possible application-related start addresses is dispensed with.
