Abstract

A method for programming a processor in a communication device arranged for communication according to a DECT/CAT-iq protocol. The method has three steps: 1) A high level language program code is provided, the program code being arranged to influence a function of the communication device. E.g. this program code may be an application program code. 2) The program code is then interpreted into a corresponding machine language code arranged for execution on the processor in the communication device. 3) Finally, this machine language is executed by the processor in the communication device. This method allows a user to program the DECT/CAT-iq device in a high level language without the need for a compiler to compile the high level language program into a processor specific machine code. Preferably, the interpreting of the high level program code is performed by the processor (P) in the communication device. Especially, the processor (P) may be programmed to operate as a virtual central processing unit (VCPU).
