Description

[Detailed Description of the Invention] (A) Technical Field of the Invention The present invention relates to an automatic inquiry cancellation processing method, in particular,
For example, when making inquiries about account numbers, etc. to the host device at a POS terminal, etc.
This invention relates to an inquiry automatic cancellation processing method that allows an application processing task to automatically return to its home position by an operator operating an alarm clear key when an NG response occurs.

(B) Technical Background and Problems Conventionally, in credit processing at the above-mentioned POS terminals, etc., an operator inputs an account number and makes inquiries to the host device, such as whether or not the account number is valid. , the credit processing is performed after waiting for the response. In this case, in the case of an NG response, conventionally, the inquiry processing task detects the NG response and notifies the error processing task. The error processing task generates an alarm based on this, and thereafter monitors whether or not the operator presses the alarm clear key. On the other hand, the control program allows the operator to cancel the above inquiry processing and start the home page of the credit operation flow in the application processing task.
It is monitored whether or not the abort key is pressed to return to the position. Pressing the former key causes the error handling task to clear the alarm. Pressing the latter key also causes the control program to notify the application processing task to return the application processing task.

Conventionally, presses of two keys have been monitored by separate programs. For this reason, the operator has to perform double operations, which is complicated. The reason why this is done twice is that there are various other cases in which returning to the home position described above exists, and the latter key press was used to unify the home position return process. It's fine.

(C) Object and Structure of the Invention The present invention aims to solve the above-mentioned problems, and by pressing the alarm clear key, a home position return operation is performed together with the alarm clear operation. The purpose is to make it possible to do so. Therefore, in the inquiry automatic cancellation processing method of the present invention, an inquiry is made to the above device in response to an inquiry from an application processing task, and the inquiry processing task processes a response message corresponding to the inquiry. , the error processing task is configured to notify this fact to the error processing task when the alarm is invalid, and the error processing task generates an alarm, monitors the press of the alarm clear key, and clears the alarm that was generated earlier when the alarm clear key is pressed. In a terminal device having an inquiry processing function, the control program is configured to notify the application processing task in the case of the above-mentioned invalidity and return to the home position in the task, in the case of the above-mentioned invalidity. The above error processing task is configured to set an invalid flag, and when the error processing task detects pressing of the alarm clear key, the above control is performed on the condition that the invalid flag is set. The present invention is characterized in that it is configured to notify the program, and that the alarm clearing operation and return to the home position are respectively performed in response to pressing of the alarm clear key by the operator. This will be explained below with reference to the drawings.

(D) Embodiments of the Invention Fig. 1 is a flowchart of an embodiment of credit operation in an application processing task, Fig. 2 is an explanatory diagram showing an embodiment of the present invention in association with processing, and Fig. 3 4 is a flowchart of an embodiment of the query processing task illustrated in FIG.
The figure shows a main part of an embodiment of the present invention and is an explanatory diagram illustrating a mode of notification between an error processing task and a control program.

The application processing task normally returns to the home position shown in FIG. 1, and if, for example, credit processing is selected, credit processing is entered. Then, by inputting the credit type, operator number, and account number, the application processing task requests the host device to inquire about the account number.
The manner of this request will be described later with reference to FIG.

If the result of the above inquiry is OK, the next step is to input the product code. If the result is NG, the application processing task is returned to its home position. In the conventional case, for the return, the operator had to press an alarm clear key to clear the alarm and press a stop key to return to the home position. This may be because the error processing task monitors and processes the former key presses, and the control program monitors the latter key presses.

FIG. 2 shows an explanatory diagram corresponding to the processing of an embodiment of the present invention. In the figure, 1 is a magnetic card reader processing task, 2 is a keyboard processing task,
3 is an input data check task which checks the format of the input data itself, 4 is an application processing task, 5 is a message editing task, 6 is a line control task, and 7 is an inquiry processing task. 8 is an error processing task, 9 is for checking the response message from the host device, etc.
10 indicates error display, 10 indicates error printing, and 11 indicates alarm generation control.

Regarding credit processing, for example, when an account number is entered using the keyboard as described above,
Task 2 receives these, and task 3 performs a format check and the like. If an error occurs at this time, the error processing task 8 instructs re-input. If there is no error during the format check, the input account number is notified to the application processing task 4. In order to perform the above-mentioned inquiry, the task 4 passes the inquiry message editing parameters to the task 5 and requests the inquiry, and also issues a request to the task 7 to perform response processing.

Task 5 creates an inquiry message and passes it to task 6, and task 6 sends the message to the host device via the line. The response message from the host device is passed to task 7 via task 6. Task 7 performs processing as shown in FIG. That is, (1) When a response message is received, it is checked whether the account number is valid. If it is legal, the answer will be NO. If it is invalid, set the account NG flag (see Figure 4).

(2) Next, check whether there is data stored in the memory, and if there is no data, the result will be NO. If so, perform data storage processing.

(3) Next, check whether there is error display data. If not, the answer will be NO. If so, perform error display processing.

(4) Next, check whether there is any error print data. If not, the answer will be NO and the process will end. If there is, an error will be printed and the process will end.

The inquiry processing task 7 operates in this way, but when the response is NG, the error processing task 8 is notified,
Task 8 generates an alarm and waits for the operator to press the alarm clear key.

In the case of the present invention, when the error processing task 8 detects that the alarm clear key is pressed, the task 8
In addition to clearing the alarm, the control program is notified that the above-mentioned account NG flag is set, and the application processing task is returned to the home position.

FIG. 4 shows the main part of an embodiment of the present invention, in which reference numeral 8 is an error processing task that responds to FIG. 2, 12 is a control program, and 13 is an account NG.
flag, 14 is the alarm clear key, 15 is the stop key, 16 is the AND logic, 17 is the alarm
The clear process and 18 represent the abort process.

Processing for returning to the home position is not limited to the case directly targeted by the present invention, and there are other cases as well. For this purpose, a cancel key 15 exists, and when the cancel key 15 is pressed, the control program 12 proceeds to the cancel process. In the case of the present invention,
As described above, when the alarm clear key 14 is pressed, the error processing task 8 detects this and performs alarm clear processing. At that time, the control program 12 is notified via the AND logic 16 that the account NG flag 13 is set. This notifies the control program to return the application processing task to its home position.

(E) Effects of the Invention As explained above, according to the present invention, the operator only has to perform an operation to clear the alarm, so that the operation is simple and there is no possibility of operational errors.
