Then, a screen in a predetermined format, such as a form, is displayed on the display device 61 based on the control information.

The contents of the screen definition body specify character information for each display item, a data input area, a display position (row, number of digits) of data key-input from the display device 61, display color and brightness, and the like. It is composed of display attributes.

Similarly, the print definition 20 is a definition of control information necessary for the screen control unit 63 to print a form or the like on the printer 62, and the content of the print definition 20 is for printing the form. Character information, print character display position (line, number of digits),
It is composed of printing area information and the like.

FIG. 2A shows an example of a screen displayed on the display device 61, and a screen definition body 10 defining such a screen display is constructed as shown in FIG. 3A, for example. The display screen (Fig. 2 (a)) has items that consist of fixed character strings (called fixed literals) such as "product name", "unit price", ... It is composed of input fields (called fields, which are blank fields surrounded by ruled lines) in which data is input for each item.

As shown in FIG. 3A, the control information for displaying the display screen on the display includes a common table, a field search table designated by the common table, a fixed literal table and vertical ruled lines. It is composed of a table and a field table designated from the field search table.

And the screen of the display device 61 is displayed as shown in FIG. Display the image as in (a).

When the operator designates a required field on the displayed display screen and inputs data (product name, unit price, quantity, etc.), the screen control unit 63 refers to the field search table and the field table. ,
Identify the corresponding fixed literal etc. of the input data,
The input data is stored in the data area 16 in association with the field, and the input data is displayed in the corresponding field on the display screen according to the designated display attribute.

Similarly, in the case of performing print output to the printer device 62, the job processing unit 65 also causes the disk device 66 to print the print definition object.
20 is read and stored in the definition area 15 and the print control unit 64 is requested to print, and the print control unit 64 refers to the print definition in the definition area 15 to perform print processing.

[0018]

As is clear from the above description, the disk device 66 is prepared by preparing different screen definition bodies 10 by the number of different types of display screens used by the business processing unit 65 in business processing. Must be stored in. Similarly for the print definition bodies 20, as many print definition bodies 20 as the number of print formats of the form to be printed are required.

On the other hand, among a plurality of formats such as different forms handled in the business, there are cases where formats that differ only partially, such as different fixed literal character strings or different field attributes, are required. is there.

However, according to the control described above, even in the case where only a part of the forms are different, a complete definition body that defines all of the forms is prepared separately for each of the different types of forms. I have to keep it.

An object of the present invention is to provide an input / output processing device in which it is not necessary to prepare a separate complete definition structure when a definition structure that is partially different from the existing definition structure is required as described above. And

[0022]

FIG. 1 is a block diagram showing the configuration of the present invention. The figure shows the configuration of an input / output processing device, in which control information defining a fixed format output to an output device is held in a definition storage unit 3 as a definition of each fixed format, and a required definition is designated. By doing so, the input / output control unit 4 is an input / output processing device that performs input / output processing according to the definition body, and the definition body change information storage unit 51
And a definition change processing unit 5.

The definition change information storage unit 51 holds necessary change information for the definition. Definition change processing unit 5
When the definition object and the change information are specified, the specified definition object is extracted from the definition object storage unit 3 and the definition object modification information storage unit 51 extracts the specified definition object according to the specified change information. The contents of the definition structure are modified, and the definition structure resulting from the modification is designated on the definition structure region 15 to cause the input / output control unit 4 to perform input / output processing.

[0024]

Therefore, the input / output control unit 4 can display and print control the display screen as in the case where another definition that is partially different from the existing definition is defined. Therefore, it is not necessary to hold a separate definition structure in the definition structure storage unit 3, and only the change information may be prepared in the definition structure change information storage unit 51.

Therefore, according to the present invention, it becomes easy to generate a definition structure that is partially different from the existing definition structure, and it is not necessary to register such definition structure in duplicate for the information of the same part. The storage efficiency of the definition program can be improved.

[0027]

EXAMPLE FIG. 4 shows a system configuration diagram of an example. Figure 4
Shows a configuration example of a terminal device installed in a branch office, and the terminal device is connected to a host computer (not shown) via a communication line 73, and has a data processing function as one terminal device in the store. Have.

That is, the terminal device includes a processing device 50 and a display unit.
A display device 61 having a 67 and a key input unit 68, a printer device 62, and a disk device 35 having a definition program storage unit 3 and a definition program change information storage unit 51.

The processing device 50 includes a screen control unit 63, a print control unit 64, a disk control unit 75, a communication control unit 72, a definition definition change processing unit 5, a job processing unit 56, and a definition structure area 15. , And a data area 16. The screen control unit 63 and the print control unit 64 respectively correspond to the input / output control unit 4 of FIG.

The definition storage unit 3 provided in the disk device 35 stores the necessary screen definition and print definition (shown as definition A in the figure) as in the conventional case. These definition bodies are composed of information as shown in FIG. 3 (a), for example.

In the case where an attempt is made to define, by the present invention, a definition structure which is partially different from the existing screen definition structure or print definition structure held in the definition structure storage unit 3 by using the existing definition structure. In this case, change information for the existing definition body is generated, and definition body update information (shown as definition body update information A1 in the figure) is stored in the definition body change information storage unit 51.

The definition definition update information will be described by using an example in which the screen definition structure of the screen of FIG. 2A is an existing definition structure and is changed to the definition structure of the screen of FIG. Figure 2 (a)
Assuming that the screen definition body for displaying the display screen is the definition body A, the definition body A is as shown in FIG.

The display characters "product name" and "unit price" on the display screen of FIG. 2 (a) are replaced with "product name" and "price", respectively.
2 (b), the information to be changed is fixed literal 1 (“product name”) character information, display position, field length and color, and fixed literal 2 (“ Unit price ”), the position of field 1, and the field length.

Further, by changing the number of digits of the fixed literal 1 from the three-digit "product name" to the four-digit "product name", the leftmost vertical ruled line (changed to vertical ruled line in FIG. 2 (a)) Make a change to move the start position (shown) to the left.

The above-mentioned contents of change are collected in, for example, definition update information shown in FIG. 3B and stored in the definition change information storage unit 51. That is, the definition update information is, as shown in the figure,
After the header part consisting of the update information name, the old screen definition object name indicating the update target, and the new screen definition object name indicating the updated definition object, the update information for each table of the definition object is configured to be continued. In the update information of each table, a set of change information corresponding to that number is shown after the number of items having a change in the table.

An example of input / output processing according to the present invention in the terminal device of FIG. 4 will be described with reference to the flow chart of processing of FIG. The business processing unit 56 performs input / output processing on the screen control unit 63.
Alternatively, when the definition unit A is used as it is when the print control unit 64 is requested, the definition unit of the disk device 35 is stored via the disk control unit 75 in the processing step 81 through the processing step 81 as in the conventional case. The definition program A is read from the copy unit 3 and stored in the definition program area 55, and in the processing step 82, the storage address of the definition program is designated and the screen control unit 63 or the print control unit 64 is requested to perform input / output processing, and the Input / output processing by the output control unit is started.

However, when the definition structure is partially changed and used, the business processing unit 56 sends to the definition structure change processing unit 5 through the processing step 80 and the processing step 83, for example, the update information name of the definition structure update information ( Specify A1) to request processing.

Therefore, the definition change processing unit 5 executes the processing steps.
At 84, the specified definition update information A1 is read from the definition change information storage unit 51 of the disk device 35 via the disk control unit 75, and the old definition name (Fig. 3 (b)), the modified definition
Knowing (assumed to be A), the definition program A is read from the definition program storage unit 3 in a processing step 85.

Next, the definition program change processing unit 5 enters a process for changing the read definition program A in accordance with the definition program update information A1. First, at step 86, the common table which is the header part of the definition program A is modified. A common table of the new definition body A'is generated on the definition body area 15.

Next, the definition program change processing unit 5 sequentially corrects each item of the table specified in the definition program update information A1, and in processing step 87, it is identified whether the definition program update information A1 has been processed to the end. However, the following processing is repeated.

That is, the definition change processing unit 5 is a processing step.
At 88, one set of unprocessed update information is extracted from the top of the definition structure update information A1, and in the processing step 89, the field designated by the table name specified by the update information is added to the definition structure A
Are sequentially searched from the remaining first table, and the contents up to immediately before the specified field remain the contents of the forward dimension in the definition area.
Store in 15.

When the designated field is taken out, it is modified in accordance with the contents of the update information in processing step 89, and processing step 90
The correction result table is stored in the definition area 15 by. For example, referring to FIG. 3, in the case of processing according to the update information of the field d of the fixed literal table, the previous field table is unchanged or modified and transferred to the definition area 15, and The first field d is taken out from the fixed literal table of the definition structure A shown in FIG.

Therefore, the definition body update information A1 shown in FIG.
In the update information of the field d of the literal table of, the change is specified in the start column, length, attribute, and character without change in the start line, so only the item specified by the change is corrected according to them. The contents shown in the table of the field d of the fixed literal table of 3 (c) are generated and stored in the definition body area 15.

When the one-field changing process is completed, the process returns from the processing step 90 to the processing step 87, and the above-mentioned processing is repeated until the definition program update information is completed. When the update information is completed, the definition processing is executed in the processing step 91. All remaining table contents of field A are stored in the definition field 15 as they are.

From the above, the definition structure A shown in FIG.
The definition structure update information A1 shown in (b) is applied and changed, and a new definition structure A ′ shown in (c) is obtained on the definition structure region 15. Therefore, as in the usual case, the storage address of the definition body is designated in the processing step 82 to request the screen control unit 63 or the print control unit 64 for input / output processing.

[0046]

As is apparent from the above description, according to the present invention, in a system in which a format of input / output processing is defined by a definition structure, when a new definition structure is required, the definition structure is separately registered. Since there is no need to create a new definition structure using the existing definition structure, there is a remarkable industrial effect that the definition structure can be easily established and the definition structure information can be retained efficiently. .
