Abstract
The present invention relates to a device and process for executing code sequences in a support comprising an integrated circuit (,) capable of executing code sequences, as well as a first memory (,) containing a main program and possibly other code sequences executable by the integrated circuit, a second nonvolatile programmable memory (,) possibly containing code sequences executable by the integrated circuit, and a third working memory (,), characterized in that an orientation table contained in the second memory (,) contains at least one field containing a code reference data element of first means (INS_INT) which make it possible to verify the presence of a code reference, to store in working memory the address data element associated with the code reference and to set a trap indicator DI, and of second means (INS_ORT) which make it possible to test the trap indicator DI, and to execute the jump to the address indicated by the contents of the working memory AD_SAUT. The device and process enable a fixed program in a portable device such as a microprocessor card to be changed.
