Abstract

PURPOSE:To obtain an output terminal changing method which does not require any change in the output process description in the job program of its own station and any repetition processing function in the job program of another station. CONSTITUTION:After an inter-computer processing mode (another station/its own station output) 1 is set in a computer system, the necessity/nonnecessity of changing an outputting destination is managed depending upon an inter- computer processing mode changing request from a job program. When an output request is made from the job program, the output is outputted to the outputting destination indicated by the inter-computer processing mode on the basis of the outputted destination changing information of the terminal of its own station previously registered on a table. When the output destination changing request is made to the terminal of another station, the output is outputted to the terminal of another station by means of the repetition processing function of another station through the inter-computer communication function of the system.

[Background Art] Conventionally, in a computer system, when a business program dynamically changes the output destination of a processing result from a terminal accommodating the own station to a terminal accommodating another station, the output destination is either the local terminal or the other station. It was necessary to determine whether it was a station terminal, and if it was another station's terminal, to transfer the output result to the other station using the inter-computer communication function, and then re-output it to the target terminal in the other station's business program. That is, in the business program of the own station, it was necessary to change the description of the output process depending on the output destination, and in the business program of the other station, it was necessary to construct a relay process via intercomputer communication process. Regarding conventional data communications, see, for example, "Electronic Information and Communication Handbook, edited by the Institute of Electronics, Information and Communication Engineers (1988), pp.2
497-2571''.
