Description

The present invention relates to an information processing system, and more particularly, to a screen display function used in an information processing system operated by a time sharing system (TSS) system. The present invention relates to an information processing system having a reception key batch determination method for checking the validity of a reception key pressed by a terminal user among input data input from a display type terminal device according to the type of a user program called to a display function.

[Conventional technology]

As shown in FIG. 3, the screen display function 7 handles the data input from the display-type terminal device 9 and the user program 8 handles the input data in the screen display processing of the conventional information processing system of the TSS system. It is performed by directly passing it to the user program 8 regardless of whether it is a system command or not. Here, the system command is a command of the time sharing system (TSS). The screen display function 7 also has a function of extracting the corresponding screen object from the screen object storage medium 10 based on the screen identification information passed from the user program 8 and transmitting the screen object to the display type terminal device 9.

[Problems to be solved by the invention]

In the above-described conventional information processing system having the screen display function, only the input data is returned to the user program that is the caller of the screen display function. Therefore, when the user program is a system command, the received input data is received. It is necessary to judge whether the key is reserved in the operating system and, if it is reserved, notify the operating system. If not reserved, the screen display function must be called again with an error message specified. The reason why the system command recognizes the reception key is that the system command notifies the operation system of the type of the reception key to determine the subsequent operation of the operation system. It is difficult to say that these processes are the original processes of system commands, and the program becomes complicated, and since multiple system commands perform these processes respectively, there is uniformity in error message and notification processing to the operating system. There is a problem of lack of. An object of the present invention is to reduce the load of system commands by the screen display function itself determining whether or not the user program is a system command, and if it is a system command, instead of performing a series of processing related to the reception key. In addition, it is to provide terminal users with uniform operability.

[Means for solving problems]

The information processing system of the present invention is an information processing system having an operation system including a system command for instructing the operation of an electronic computer, in which a screen object storage medium, a display type terminal device, and screen identification information passed from a user program. Then, the corresponding screen object is taken out from the screen object storage medium and transmitted to the display type terminal device, and then the control is returned to the user program together with the reception key input by the terminal user, and the screen display function and the screen display User program determining means for determining whether or not the user program is a system command before the function returns control to the user program and returning control to the screen display function when the user program is not a system command, User program is Reception command determining means for determining whether or not the reception key is reserved in the operation system when the reception command is a system command, and reception for notifying the operation system of the type of the reception key when the reception key is reserved in the operation system. Key notification means, and error setting means for setting an error message when the received key is not reserved in the operation system and displaying a screen accompanied by the error message on the display type terminal device through the screen display function. And a receiving key batch determining means having the following.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a flow chart showing details of its operation.

As shown in FIG. 1, the reception key batch determination means 1 is used by connecting to the screen display function 7, and is used as a main control unit 2, a user program determination unit 3, a reception key determination unit 4, an error setting unit 5, The reception key communication unit 6 is included. The screen display function 7 retrieves the corresponding screen object from the screen object storage medium 10 according to the screen identification information passed from the user program 8, transmits it to the display type terminal device 9, and then the keystroke from the terminal user. When the reception key is received as input data together with the data, the conventional screen display function returns the control to the user program 8 with the input data. Pass control to 1.
Further, when returning from this reception key batch judgment method 1 with an error message, the error message is added to the screen displayed immediately before and the screen is displayed again, and the reception key batch judgment means 1 displays an error message. When the processing is normally ended without accompanying, the control is returned to the user program 8 as usual.
Here, the reception key is a kind of the key of the display type terminal device 9 which is a part of the input data and is pressed immediately after the terminal user taps the data from the display type terminal device 9. A send key or a function key. The user program determination unit 3 has a determination function of determining whether the user program 8 is a system command, and the reception key determination unit 4 has a determination function of whether a reception key is reserved in the operation system. Have. The error setting unit 5 sets an error message for notifying the terminal user when a reception key not reserved in the operation system is input, and the reception key notification unit 6 is reserved in the operation system. In the case of a received key, the main control unit 2 is a control unit for notifying the operation system of the type of the received key, and the main control unit 2. The operation system has a function of selecting an input prompt screen to be displayed after the completion of the system command according to the notified type of the receive key, and reserves the type of the receive key assigned to each input prompt screen. There is.

Next, the operation will be described in detail with reference to FIG. When receiving control from the screen display function 7 to which the user program 8 has received control, the reception key batch determination means causes the user program determination unit 3 to determine in step S1 whether the caller of the screen display function 7 is a system command. It is judged by the information from the operation system. As a result, if it is not the system command, the screen display function 7
Return control to. On the other hand, if the received command is a system command, the reception key determination unit 4 determines in step S2 whether or not the reception key is reserved in the operation system by referring to the reservation key table. If the reception key is reserved, the reception key communication unit 6 notifies the operation system of the reception key in step S3. Thus, after the completion of this system command, the type of input prompt screen displayed by the operating system is determined. If it has not been reserved, step S
At 4, the error setting unit 5 sets an error message. Now, when these processes are completed, the reception key batch determination means 1 returns the control to the screen display function 7.

〔The invention's effect〕

As described above, according to the present invention, in the terminal data input by the terminal user, the system command is executed by collectively performing the complicated processing related to the reception key, which is performed by the system command, as the processing of the screen display function. There is an effect that the complexity of the program is reduced, and that the terminal user can obtain uniform operability regardless of which system command is used.
