摘要：
A microprocessor-controlled device with software files stored in non-volatile memory which can be easily modified by the user by reading or scanning a two-dimensional bar code symbol having program modification information encoded thereon. The symbol can be read by two-dimensional or one-dimensional laser or CCD based means. Depending on its size, either the entire file can be replaced, selected locations can be replaced, or selected relocatable object files can be linked at the target device in order to effect the program revision.
