DATA PROCESSING APPARATUS WITH COMMUNICATION FUNCTION

When chat is performed with remote persons by using a personal computer communication service, even if the conversation data is displayed in a disordered chat style, a display having good visible readability can be performed such that conversation data of the persons who participate the chat are independently displayed in specific styles. For example, when the contents of the communication buffer in which all of the conversational data are stored are transferred to the storage device as a file, it is determined whether the data is transmission data or reception data. If the data is reception data, predetermined modification information, such as an inverted display, is added and the data is then stored in the file. When the contents of the file are output, the reception data is modified according to the modification information and then output.
