Abstract

PURPOSE:To improve the efficiency of the system editing work by changing contents of an individual processing part provided correspondingly to an input/ output device to edit the system at the time of the change of specifications of this input/output device connected to a data processing system. CONSTITUTION:At the time of the change of specifications, only editing procedures of an individual processing part 12 corresponding to the pertinent input/output device are changed to improve the version of the individual processing part 12. Consequently, some individual processing parts 12 have a version (n) and others have a version (m), and individual processing parts 12 are different by version numbers. Another individual processing part 12 having a version 0 is generated for a newly set input device, and this version is successively improved at the time of the change of specifications. It is unnecessary to change a main processing part 11 because this processing part 11 performs the processing in accordance with editing procedures described in individual processing parts 12, and therefore, the system editing work accompanied with the change of specifications of input/output devices is facilitatted.

When a new input / output device is connected to the above-mentioned POS terminal device or when the function of the existing input / output device is changed, a system editing tool for performing system editing again. It is also necessary to change the screen format and data processing procedure within 10. However, in the conventional system editing tool, since the screen format and the data processing procedure are not described for each input / output device, the entire system editing tool 10 had to be revised when the above change was made. The system editing tool 10 shown in FIG.
It indicates that it has been revised n times. Therefore, there is a problem that a large number of man-hours are required to revise the system editing tool even if the specifications of the input / output device are slightly changed.

Therefore, an object of the present invention is to improve the efficiency of system editing work.

[0007]

To solve the above problems, in a system editing method of a data processing system to which input / output devices are connected, the editing processing procedure of the corresponding input / output devices is provided for each input / output device. A plurality of individual processing units 12 described and a main processing unit 11 that performs editing processing according to the description of the individual processing unit 12, and when the specifications of the input / output device are changed, the individual processing unit corresponding to the input / output device This is achieved by a system editing method characterized in that the contents of 12 are changed and the main processing unit 11 performs system editing according to the description of the individual processing unit 12.

[0008]

The present invention is provided with an individual processing section 12 which describes an editing procedure for each input / output device, and a main processing section 11 which performs system editing according to the description of the individual processing section 12. Therefore, even when the specifications of individual input / output devices are changed, system editing can be performed by simply changing the editing procedure of the individual processing unit 12 corresponding to the changes, and the system editing work is easier than in the past. Become.

FIG. 1 is a diagram showing the operation of a system editing tool according to an embodiment of the present invention, and those having the same functions as those in FIG. The system editing tool 10 is composed of a main processing unit 11 and an individual processing unit 12. The individual processing unit 12 is provided according to the input / output device, and the editing procedure of each input / output device is described. The main processing unit 11 refers to each individual processing unit 12 and performs a process in accordance with its contents. FIG. 2 is a diagram showing the contents of the individual processing unit 12, which checks the input / output device name, the screen format related to the input / output device, and the appropriateness of the data when the operator inputs a key to the screen displayed according to this screen format. It describes a data check procedure to be performed, a data format conversion procedure when storing keyed data in the DASD 30, a program name to be output to the DASD 30, and the like. FIG. 3 is a flow chart showing an embodiment of the present invention. Embodiments of the present invention will be described below with reference to FIGS.

First, a message indicating whether or not an input / output device is connected is displayed on the screen 40 according to the screen format of the main processing section 11 (S1). Then, according to the displayed message, the operator key-inputs a parameter for determining whether or not the input / output device is connected, for example, whether or not the printer is connected (S2).

Then, the individual processing unit 12 corresponding to the input / output device which is connected according to the setting of the above parameters is activated (S3). For example, when the printer connection is set, the individual processing unit 12 for the printer is activated.

Then, a message is displayed on the screen 40 according to the screen format of the activated individual processing section 12 (S4). The message is for allowing the operator to select the type of printer and the printing speed, for example.

Then, the operator sets necessary parameters by key input according to the above message (S
5). For example, the type of printer and the printing speed are set. Next, a proper check whether the set data is suitable for the input / output device and the DAS
Data processing such as data format conversion processing required for storage in D30 is performed according to the procedure described in the individual processing unit 12 (S6), and stored in DASD 30.

If there is another input / output device to be connected (S7), the process returns to S3 to activate the individual processing unit 12 corresponding to the input / output device and perform the same processing. After that, as described in the section of the prior art, the program for controlling each input / output device and the application program are input.
Then, the system is operated by reading it out and storing it in the DASD 30.
