Abstract: A customer browser and an agent browser are connected to each other through a collaboration server, and a Web server is controlled so as to be accessed through the collaboration server. When the browsers and refer to a page, the collaboration server embeds an applet for detecting a change in the page and a client controller for displaying a page corresponding to changed page information of the other party which performs collaboration. When the customer and agent browsers detect the change in the page, the applet is invoked, and the changed page information is sent to the other party via the collaboration server, and the client controller on the other party controls the browser so as to display the changed page.

Abstract: For each screen appearing in an application to be automatically executed, information for spacifying the screen (e.g., a screen number or a characteristic message) is recorded, to be compared with another at the time of re-execution to confirm that the automatic execution is being carried out in accordance with a predetermined procedure. An action procedure (e.g., PA2 KEY) for each screen is recorded in preparation for appearance of an exceptional screen. Software is provided for recording an operational procedure of a keyboard or screen position's designation of an input/output variable and, thus, an operator is capable of recording screen specifying data, input variable data and output variable data while an application is being executed.
