Abstract
In a conferencing system including a plurality of workstations each having a multiwindow function connected to each other via a network, programs loaded in the respective workstations to control a conference are linked with each other through a logical circular control program's path. A data item inputted from a workstation not having a data effectuation floor qualification is transmitted as a data item in an ineffective state to a next workstation. When received by a workstation possessing the effectuation floor qualification, the data in the ineffective state is converted into an effective data. In each station, application programs and utility programs are responsive only to the data in the effective state, which guarantees the identity of results of data processing achieved in the respective workstations.
