Abstract

PURPOSE:To package applied programs by separating a decision switching function to expose them outside, and making the applied programs independent of each other. CONSTITUTION:When work programs A and B of a terminal 11, a work program B of a terminal 12, etc. are informed to a terminal controller 2'; the processing name is set into a telegram which is outputted for the first time after the initial program loading (IPL) is executed with said programs, respectively. Then the telegram is sent to a program decision switching part 11 within an action control station (OS)3', and the processing name is decoded for switch to the corresponding application programs (process A) 121 and (process B) 122. The part 11 transmits the subsequent telegrams as they are as long as they belong to the same program to a program once selected. In this respect, different levels are set to programs A and B, for example, and an existing gate circuit is used to carry out a switching action.

It consists of OS) S and application program 4, the former controls the operation of the data processing system including the terminal, and the latter runs different processing programs depending on whether the terminal's business is online trading or word processing. It consists of functions for determining and switching and respective processing programs.

る。That is, when the business programs A and B stored in the terminal 11 are replaced, for example, on a floppy disk, the application program 4 in the figure uses the determination function 5 to determine whether the processing program 61 of program A or the processing program 62 of program B is replaced. . For example, when the program A of the terminal 11 is running, the application program 2m 4 of the human telegraph terminal controller 2 is notified.

切換え処理を行なう。Each time a message arrives, the application program 4 determines whether it is a person's message or B's message, and performs switching processing to the person's processing program 61. Further, when the program B of the terminal 11 is running, a similar process is performed to switch to the processing program 62 of #)B.

In some cases, the application program must be completely changed, there is no flexibility in replacing programs within or between terminals, and it is not suitable for packaging.
