Abstract

A data carrier for interpreter-based execution of an application existing in the form of an application program resulting from an object-oriented source program includes a communication device (10), and a memory device (12) containing at least one application program and an interpreter unit (15). The application program is structured in class files (22) each containing a library section (25) whose entries (46) are formed by invariable elements of the interaction context and which is structured in a sequence of equally long segments (50) each comprising a predetermined number of bytes. A certain number of segments (5) forms an entry (46). The physical position of the first segment of each entry (46) within the byte sequence is used by the interpreter unit (15) as a reference for the entry (46).
