<p>PURPOSE: To efficiently process mixed data objects inside a data stream by marking the respective plural mixed data objects by a label for indicating the type of the object and selectively calling a specified application corresponding to it. CONSTITUTION: The respective mixed data objects inside the data stream are provided with a pair of object break symbols and an environment control mark. In response to the detection of the start of the respective objects, an appropriate application for processing the object is called and returned after the processing of an interposed object. The processing is performed by using environment elements from a present object or a previous object. Thus, while the specified application is matched with the specified object used for the processing, a coordinate system, a color, a measurement unit or a present position is shared among the objects. Thus, the mixed data objects inside the data stream are efficiently processed.</p> |
