Abstract
Abstract @ A system in accordance with the present invention is arranged to carry out data processings by selecting and combining basic functions provided in a pocket-size hermetically sealed electronic device by operating from an external equipment. The pocket-size hermetically sealed electronic device includes a mask ROM (36) which is memorizing programs for realizing a plurality of kinds of basic functions, a RAM (38) which memorizes various kinds of data that accompany the basic functions, a connection section (40) which receives a command that includes at least function codes for selecting programs of the plurality of kinds of basic functions based on a command from the connection section, and carries out the functions in accordance with the prog- i rams selected.
