Abstract

PURPOSE:To improve the preparation of a program and maintenance efficiency by integrating the processing in a terminal equipment and the description of a host computer processing into one body when an on-line real time processing job is constructed and to cope with the case plural types of terminal equipment coexist by executing a decoding on the side of the terminal equipment at a point of time when a terminal equipment processing part in the state of an intermediate language is stored in a host computer and is executed. CONSTITUTION:In this system, a decoding separation means 1 separating a source program into a terminal equipment processing part and a host computer processing part, a terminal processing part transmission means 8 transmitting the start of the host computer processing part and the terminal equipment processing part to the terminal equipment by the instruction from the terminal equipment and a terminal decoding execution means 6 performing the decoding and execution of a terminal processing part in the terminal equipment are provided. The terminal equipment processing part is stored in the form of an intermediate language within a host computer and the decoding is executed by the terminal equipment at a point of time of the execution.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an online real-time processing system, and more particularly to an online real-time processing system which requires processing in a terminal device.

[0002]

2. Description of the Related Art A conventional online real-time processing system is a method for controlling an on-screen utility and an input item by activating an online utility on a terminal device as shown in FIG.
As shown in FIG. 4, it is a method of starting an online program for each business in a terminal device and performing data communication.

[0003]

In the conventional online real-time processing system described above, in the conventional system shown in FIG. 3, the terminal device is controlled by the control code in the transmission / reception data, and therefore the format of the screen and the number of digits of the input item are used. There is a problem only in controlling the attributes such as and alphanumeric characters, in controlling the flow of execution according to the calculation of the input value and the input item value, and in the terminal internal processing such as the file processing of the terminal device. In the conventional method shown in FIG. 4, since the terminal device has a program for each business, the terminal device can perform internal processing of file processing and arithmetic processing, but on the other hand, since the business program needs to be set in the terminal device, the process can be changed. When it occurs, it is necessary to set it again in the terminal device, and it is necessary to create a different load module for each terminal model, which causes a problem that the creation work and the maintenance work are laborious. Further, in the case of processing change, it is necessary to synchronize the change of the host program and the terminal device program, and there is a problem that maintenance is difficult.

[0004]

According to the online real-time processing method of the present invention, a decoding / separating means for separating a program into a host computer processing section and a terminal apparatus processing section, and a terminal apparatus processing section is provided with a terminal apparatus processing section according to a request from the terminal apparatus. And a terminal decryption executing means for decrypting and executing the processing portion transmitted on the terminal device side.

[0005]

Embodiments of the present invention will now be described with reference to the drawings.

The program of the online real entry business of the online real entry business processing of one embodiment of the online real-time processing system of this embodiment is composed of one source program, and the processing contents of the host computer and the terminal device are as follows. Describe in one program. As shown in FIG. 1A, the described program is separated into a host computer processing unit and a terminal device processing unit in advance by the decryption / separation unit 1 and stored in the external storage device 2 of the host computer.

In this work, as shown in FIG. 1B, the terminal device is connected to the host computer through a communication line, and a plurality of terminal models are mixed. 3, an input device 4, and a terminal processing device 5.

First, in response to the activation request 7 from the terminal decoding execution means 6, the terminal processing part transmission means 8 reads the terminal device processing part 10 from the external storage device 9 of the host computer and sends 11 to the terminal device.

The host computer processing unit is activated 12 together with the transmission of the terminal device processing unit. In the terminal device, the terminal device processing unit 1 transmitted by the terminal decoding execution means 6
Decrypt and execute 3. After that, the input / output data 14 is processed by the terminal processing unit 13 and the host computer processing unit 15.

FIG. 2 (a) shows the terminal screen state 21 of the work execution state and the terminal device processing contents 22. When the customer code 23 and the product code 24 are input, the customer master 25 and the product master of the terminal device. The presence check of 26 is performed, and after inputting all items, the input data is transmitted from the terminal device to the host computer. During this time, the processing is performed inside the terminal device and does not put a load on the host computer.

In the host computer, the host computer processing unit 32 receives the data 31 received in FIG. 2B and writes it in the order file 32.

By providing the terminal device with the check master, the processing is shared between the host computer and the terminal device, and the load on the host computer is reduced and the operability is improved by checking the input items of the terminal device.

[0013]

As described above, according to the online real-time processing method of the present invention, the program of the terminal device and the host computer can be integrally created and maintained, so that the efficiency of the program development can be improved and the terminal device can be preliminarily prepared. It is not necessary to prepare a program and maintenance is easy. By effectively using the functions of the terminal device, the load on the host computer can be reduced and the operability of the terminal device can be improved.
