JPS63291109A - System for managing input data status for on-line terminal screen - Google Patents

Abstract

PURPOSE:To interrupt an input and to reuse input information by using an external storing device, temporarily storing screen input data and realizing a status with a transmission buffer control task. CONSTITUTION:A large capacity storing means 12 to temporarily store screen input data with an on-line and a processing means to have a storing area to control the status information of the screen input information with a transmission buffer managing task 13 are provided. Thus, even comparatively long screen input data can execute at the time of input, a temporary interruption and a restarting. in the case of the same information, the information transmitted to a center at the previous time can be re-displayed in the screen and the item of a variation part only can be inputted and transmitted. When transmission information goes to an error with the check of the center side according to the contents of the error, transmission data are re-displayed in the screen and only the error item can be corrected and transmitted again.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an online data communication system, and particularly to a method for managing screen input data of an online terminal.

(Prior Art) Conventionally, the screen input information of this type of online terminal was simply stored in the internal memory of the terminal, and was immediately transmitted when the input was completed. Therefore, there was no need for special status management of screen input data.

(Problems to be Solved by the Invention) Screen input data in the above-mentioned conventional online terminals is immediately transferred to internal storage for transmission and reception, so input may be interrupted while screen information is being input. The disadvantage is that it cannot be done. In addition, when inputting information on the next screen, it is not possible to reuse the information that was input previously for each information.
The disadvantage is that you have to re-enter the information from the beginning.

An object of the present invention is to temporarily store screen input data using an external storage device and to manage the status using a transmission buffer management task, thereby eliminating the above-mentioned drawbacks and eliminating the need to interrupt human labor. An object of the present invention is to provide a screen input data status management method for an online terminal configured so that input information can be reused.

(Means for Solving the Problems) A screen input data status management system for an online terminal according to the present invention is configured to include a large-capacity storage means and a processing means.

The mass storage means is for temporarily storing screen input data online.

The processing means has a storage area for managing state information of screen input data in a transmission buffer management task.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

Referring to the figure, the screen input means keyboard/CRT
A display 11, an external storage 12 such as a 70-bit disk for storing screen input data, a transmission buffer management task 13 for managing screen input data in information units by status, and an input management table 14. , a preliminary business processing task 15 that provides an opportunity to update the status, a transmission/reception processing task 16, and an operation management task 17.
, a line termination device 18 , a kanji printer 19 , and a power source.

Referring to FIG. 2, in the input management table 14 for managing status in units of information, each piece of information is managed by bits representing five states: input interrupted, input completed, transmission possible, transmission in progress, and transmission completed. There is. Each bit is %
When it is II, it indicates the display state, which is summarized as shown in the table below.

(Table) Referring to FIG. 3, the relationship between online terminal operations and status transitions is processed in steps 301-320.

In FIG. 8, upon startup of the online terminal in step 301, a program is loaded into internal memory. In step 302, one of the plurality of external memories for information input (floppy disk) 12 is selected and set. In step 303, an initial double-sided display is displayed according to operation management task 1 in FIG. 1, and a list of information names that can be input is displayed on the screen.

In step 304, the operator selects the information he wishes to send to the center (not shown). At this time, at the same time,
The program displays a guidance screen for inputting the selected information. In step 305, the operator inputs information items on the input screen. In step 306, when the input of the information unit is completed, the operator presses the input completion key.

Next, in steps 308 and 310, the transmission buffer management task 13 in FIG. 1 stores and inputs information in external storage according to instructions from the business processing task 15.

Set to completed state. In step 312, the operator issues a transmission request. At this time, the business processing task 1S in FIG. 1 issues a transmission request to the transmission/reception processing task 16. At the same time, in step 313, an instruction is sent to the transmission buffer management task 13 to enable transmission. In steps 314 and 315, the transmission/reception processing task 16 of FIG. 1 obtains screen input data from the transmission buffer management task 13, requests to change the status to transmitting, and sends a request to the center (not shown).

) send a message to.

In step 316, the transmission/reception processing task 16 of FIG. 1 determines the response message of the center (not shown). If the sensor response is normal, step 319 is entered and the transmission buffer management task 13 in FIG. 1 executes the transmission processing task 16.
After receiving the transmission completion notification from , the transmission is completed. If the center response is abnormal, step 317 is entered, and the transmission buffer management task 13 in Figure 7a1 executes the transmission/reception processing task 16.
Input is interrupted after receiving input relay notification from .

In step 307, the operator presses the input interrupt key during information input. In step 309, the first
The transmission buffer management task 13 in the figure is a business processing task IS.
In response to an external storage storage instruction, the screen input data is stored in the external storage 12.

In step 311, the transmit buffer management task 13
In accordance with the instructions of the business processing task 15, the information input is suspended.

(Effects of the Invention) As explained above, the present invention uses an external storage device to temporarily store screen input data, and also realizes the status using a transmission buffer management task. It has the effect of being able to temporarily stop and restart even relatively long screen input data, and secondly, in the case of the same information, the information sent to the center last time can be redisplayed on the screen, and only the changing part can be displayed on the screen again. item? It has the effect of being able to input and send data, and the eighth point is that it can be sent to the center.

If the sent information turns out to be an error when checked by the center, it is effective to re-display the sent data on the screen according to the content of the error, correct only the error items, and send again. 4. When the external storage is full, the erasure order is determined in advance for each management status, and the status of each piece of information is referred to in advance so that the information can be automatically erased using a program.
