Abstract

PURPOSE:To change all attributes of individual items relating to a basic item automatically by defining the attributes of the individual items according to the relation with the basic item and changing attributes of the basic item. CONSTITUTION:Basic attribute definition information from an input/output device 2 is registered in a file 1. This information is only basic information selected in consideration of the level, etc., of frequency of use among various items used in plural programs which relate to one another. The relation between the item of a part of an original source program 3 corresponding to an attribute definition part and the atrribute of the basic item registered in the file 1 is described in the source program 3 at the part corresponding to the attribute definition part. An attribute relation description part extracting part 4 extracts the attribute relation description part in the source program read out of an original library 3 and passes it to a description conversion part 5. The conversion part 5 receives the attribute relation description part and converts it into the attribute definition part of the corresponding item while referring to the file 1 and writes it in the library 6 stored with a final source program.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for defining attributes of items when creating a program.

For items used in conventional technology programs, their attributes are defined as 0, for example in the COBOL language.

For basic items, the class and number of digits that indicate whether it is alphabetic, numeric, or alphanumeric are defined as attributes, and for group items, the total number of digits assuming that all the classes of basic items subordinate to it are alphanumeric. is defined as an attribute.

Problems to be Solved by the Invention Accordingly, changing the attributes of a certain item not only affects each part within the program, but also affects many related programs. Furthermore, changes to a basic item also affect the attributes of all group items to which it is dependent. As a result,
There is a problem in that a large amount of time must be spent on researching, searching, changing, etc. necessary changes within a program and between items between programs.

Composition of the Invention Means for Solving the Problems The present invention solves the above-mentioned conventional problems: Basic attributes that define the attributes of basic items among various items used in a plurality of mutually related programs. Register definition information;
For the items used in the program, create an original program that includes an attribute relationship description part that describes the relationship in attributes with the above basic items; extract the above attribute relationship description part from the original program, and define the above basic attributes. The apparatus is configured to obtain a final program including attribute definition parts of two items by supplying the original program to a device that converts the attribute definition parts of the corresponding items based on the information.

The operation of the present invention will be explained in detail below using examples.

Embodiment FIG. 1 is a block diagram showing the configuration of an apparatus used in an embodiment of the present invention.

In the figure, ■ is a file that registers basic attribute definition information, 2 is an input/output device for registering and updating the contents of file 1, 3 is a library that stores the original source program, and 4 is the original source program. 5 is a description conversion unit; 6 is a library for storing the final source program; and 5 is a description conversion unit.

First, basic attribute definition information is registered from the input/output device 2 to the file 1. This basic attribute definition information is created for basic items among various items used in a plurality of mutually related programs, taking into account the frequency of use and the like. For convenience.

The above basic items are extracted from a series of programs that have a common purpose (for example, a financial management program).

This may be done by extracting all items used in the most basic program (such as a human resources management program).

An example of the format of the above basic attribute definition information using the COROL language is as shown in FIG. 2(B). This is nothing but the attribute definition part that was conventionally written in each side's program.

In the original source program, the attribute relationship between the item and the basic items registered in the file l is described in a part corresponding to the conventional attribute definition part. This attribute relationship description part consists of two basic items [W-MONYJ is an attribute (ATTR) as shown in FIG. 2(A).
T BUTE), the basic basic items, “MoN
Y”: group item rW-ZA1. MUJ is
In the attribute (ATT), the basic group item “ZAIM
[J − Same as RJ: It is described as follows.

The attribute relationship description portion extraction unit 4 extracts the attribute relationship description portions in the original source program successively extracted from the library 3 and passes them to the description conversion unit 5. The description conversion unit 5 receives the attribute relationship description part.

While referring to the file 1, the attribute relationship description part is converted into the attribute definition part of the corresponding item and written into the library 6.

For example, the attribute relationship description molecule W-MONY ATT MONYJ in the original source program.

As shown in FIG. 3(C), the second item rW-MONYJ is a signed 10-digit number.
It is converted into the attribute definition part Y Pr'C59(10)-J, and the attribute relationship description part W-ZAIMU
ATT ZATMU-Rj.

rW-ZA-rMtJ PTCX (34) indicating that the group item "W-ZAIMU" is 34 alphanumeric characters.
It is converted into an attribute definition part named J and stored in the library 6.

The attribute relationship description portion extraction unit 4 immediately writes to the library 6 any portion of the original source program read from the library 3 that does not correspond to the attribute relationship description portion.

The final source program stored in library 6 is
Compiled to create an object program. On the other hand, the original source program is saved in the library 3 in preparation for changing the attributes of the items at a later date.

In the example shown in Figure 2, the number of digits of the basic item r'MONYJ registered in the basic attribute definition information file 1 will be changed to 1 at a later date.
Assume that the number has been changed from 0 digits to 12 digits. In this case, use input/output device 2 to change the attribute of rMONYJ in file 1 from rs9 (10)'J to rS9 (12)J, and change the attribute in the original source program saved in library 3. The attribute relationship description portion may be converted into the attribute definition portion using exactly the same method as described above. On this occasion,
Attribute definition part molecule in the final program, W-ZAIMUJ
The task of changing the number of digits from 34 to 36 is automatically performed without the user paying any attention. That is, the attribute relationship description molecule W in the original source program
- ZAIMU ATT ZAT Based on MU-RJ, rW-ZATM in the final source program
The attribute definition part U PICX (36) J is automatically changed.

Although the present invention has been exemplified in the case of a source program, the present invention can also be applied to the case of an object program.

Further, the present invention has been described using an example in which one item is a letter or a number, but if one item is graphic data or the like, the attribute may be the number of brightness gradations, the number of color codes, etc.

Effects of the Invention As explained in detail above, the present invention has a configuration in which attributes of individual items are defined in relation to basic items, so by changing the attributes of basic items, All the attributes of the individual items related to the will be changed automatically.

Therefore, unlike the conventional technology, we need to investigate the changed parts.

You don't have to spend a lot of time searching, making changes, etc.

You can quickly and accurately change item attributes.

This has the effect of eliminating errors such as omission of changes.
