Abstract

PURPOSE:To deal with the change of an order for inputting picture input items without changing a program only by changing the contents of an input item management file when the order of inputting the picture input items is changed. CONSTITUTION:A first input means 1 inputs item input/output order numbers on a screen. An analyzing means 2 analyzes the item input/output order numbers. A storing means 3 stores item information corresponding to the item input/output order numbers. A processing means 4 acquires the item information from the storing means 3. A second input means 5 inputs data according to the item information. A first output means 6 outputs the data of the items inputted by the second input means 5 according to the item information. A second output means 7 outputs the item numbers stored in the data and the item information.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for an input / output device having a screen input / output function in an information processing system.

[0002]

2. Description of the Related Art Currently, most information processing systems have an input / output device having a screen input / output function, and there are various methods for controlling the input / output device.

As a conventional control method, definitions and commands relating to input / output items on the screen are described in a program to control the input / output device.

[0004]

The above-mentioned conventional control method for the input / output device controls the input / output device by describing the definitions and commands relating to the input / output items on the screen in the program. When the input order of screen input items is changed, it affects the position on the screen, that is, the flow of definitions and commands written in the program, so that the program must be changed and reliability is lowered. There are drawbacks.

Further, in recent years, in system development, a system of the same industry developed previously is often diverted and constructed, and if there is a difference in the input order as in the previous example, much time and effort are required for development. It also has the disadvantage of requiring it.

[0006]

According to the present invention, "in the screen input / output of the information processing system, the first input means for inputting the item input / output sequence number on the screen and the input by the first input means. Means for analyzing the item input / output sequence number, storage means for storing item information corresponding to the item input / output sequence number, and item information corresponding to the item input / output sequence number from the storage means. Processing means to obtain,
Second input means for inputting data according to the item information, first output means for outputting data of the item input by the second input means according to the item information, the data and the item And a second output means for outputting the item number stored in the information ".

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a more detailed description will be given with reference to the drawings showing an embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention is
Connected to the input device 8 and the output device 9, the first input means 1, the analysis means 2, the storage means 3, the processing means 4, the second input means 5, the first output means 6, The second output means 7 is configured.

FIG. 2 is a flow chart showing the flow of processing of the control method of the input / output device. The function and operation of the input / output device control method will be described below.

In the program, the screen is displayed, the item input / output sequence number (usually "1") on the screen is transferred to the first input means 1, and the process is shifted to the control system of the input / output device. The first input means 1 receives the item input / output sequence number from the program. The storage unit 3 is an input item management file as shown in FIG. 3, and manages the maximum number of items in the first record, and the subsequent records store items corresponding to item input / output sequence numbers.

The item information includes an item number indicating the item name, a line indicating the screen information, a column, an attribute, the number of digits, an initial filler, and an input device. The analysis means 2 compares the item input / output sequence number transferred to the first input means 1 with the maximum number of items in the input item management file, and satisfies the condition (item input / output sequence number ≦ maximum number of items). If so, the item input / output sequence number is passed to the processing means 4. If the condition is not satisfied, the second output means 7 is posted that the item input / output sequence number transferred to the first input means 1 is incorrect, and the process is returned to the program. The processing means 4 reads the input item management file using the received item input / output sequence number as a key, and acquires the corresponding item information.

The second input means 5 requests the item data from the input device 8 according to the item information acquired by the processing means 4. The input device 8 is, for example, a keyboard, a card reader, or the like. The first output unit 6 outputs the data of the item input by the second input unit 5 according to the item information acquired by the processing unit 4 and outputs the output device 9
To display. The item number stored in the input item management file and the data input from the input device 8 are transferred to the second output means 7, and the process is returned to the program. The output device 9 is, for example, a CRT screen.

The program that has been returned to the processing branches to the input value inspection processing of the corresponding item according to the item number passed by the second output means 7, and determines whether or not the input value is acceptable.

Next, in order to input the next item, the item input / output sequence number is incremented by 1 and transferred to the first input means 1, and then the process is shifted to the control system of the input / output device again.
In this way, items on the screen are sequentially input by incrementing the item input / output number.

Next, a changing method when the input order of the screen is changed will be described with reference to FIG. As in the screen 10 before change, "1 employee number", "2 employee name",
When inputting in the order of “3 hire date”, the contents of the input item management file are the input item management file 11 before change.
The maximum number of items is "3", the item input / output order is "1, 2, 3", while the item numbers are "1" for employee numbers, "2" for employee names, and date of entry. Is set to "3".

Like the post-change screen 12, the pre-change screen 10 shows "1 employee name", "2 employee number", "3 hire date"
In this way, when the input order is changed, the contents of the input item management file are changed and the input item management file 13 is changed.
To change. That is, the item input / output order "1, 2,
For "3", the item numbers are reset in order of "2" for the employee name, "1" for the employee number, and "3" for the date of joining the company.

As described above, when the input order of the screen is changed, it is not necessary to change the processing flow on the program by changing the contents of the input item management file.

[0018]

As described above, according to the present invention,
When the input order of screen input items is changed by storing the item information corresponding to the item input / output number of the screen in the input item management file, the contents of the input item management file are changed. It is possible to deal with the change of the input order of the screen input items without changing the program only by performing the.

Therefore, in the development of the information processing system, it becomes easy to divert and construct the system of the same industry developed previously, and there is an effect that the quality is further improved.
