2. Description of the Related Art In recent years, an online system for various kinds of work has been advanced, and a large amount of online work processing programs used in these systems have been developed. Improving the productivity of business processing programs is the most important issue.

In such a situation, the development environment of the online business processing program has hitherto been performed on the general-purpose computer of the main framer on which the online business processing program actually operates in the development environment suitable for the model and the OS. However, due to lack of development personnel and soaring land prices, it has become difficult to perform concentrated development in one place as in the past.
Therefore, in order to solve these problems and respond to the demand for online business processing program development, a distributed development environment that does not depend on the execution environment is currently in place, and system scalability, economy, operability, etc. It is becoming mainstream to build a distributed development environment centered on excellent workstations (WS).

In the development of an online business processing program for a large-scale system in such a distributed development environment, upstream processes such as required specification analysis and design to a unit test process are performed. Generally, in the unit test process, the symbolic debugger prepared in the development environment is used.In this, the compiler for the symbolic debugger is used in the development environment to generate the objects of the online business processing program under test in advance. It is necessary to set.

Further, in order to improve the productivity of the online business processing program by porting and diverting the online business processing program, online business processing that eliminates the port obstruction factor that depends on the architecture for the specifications of the compiler in the execution environment. It is also common to adopt a method of defining a program description language specification and performing online business processing program source coding within the range of the description language specification. However, it is up to the programmer to decide whether or not to comply with this online business processing program description language specification, and the portability is not guaranteed. As a technique for guaranteeing portability, there are check tools such as UNIX lints or commercially available products such as "C coding diagnostic system", and these are all targeted for the source code described in C language.

The COBOL language is still widely used as the online business processing program description language for large-scale online systems. At present, however, the development support tool for the COBOL language on UNIX-WS is more than that for the C language. Poor tool assortment and lack of support for Japanese, it is inferior in operability and work efficiency.

[0007]

In consideration of the distributed development and online business processing program description language specification in the above-mentioned online business processing program development (especially UNIX-WS as a development environment and COBOL as a programming language), the following problems are encountered. There is.

Since the online business processing program finally runs on the execution environment, the online business processing program description language specification is, in principle, a subset of the compiler specifications on the execution environment. The specification of the compiler on the execution environment does not usually match the specification of the compiler on the development environment. In particular, in the COBOL language, it is general that there are specifications depending on the execution environment such as optimization options for memory allocation. Therefore, even an online business processing program coded according to the online business processing program description language specifications will generate an error when compiling in the development environment and the object will not be generated correctly.
It may not be possible to test a single unit of an online business processing program that uses a symbolic debugger.

To solve this, each programmer recognizes the inconsistency between the compiler specifications on each environment, and when the online business processing program unit test is performed, the source code is changed so as to match the compiler specifications of the development environment. When migrating an online business processing program that has been manually modified and finished unit testing to the execution environment, it is necessary to manually modify the source code to match the compiler specifications of the execution environment. Not only was the programmer's burden increased due to the code modification, but there was also a problem such as the deterioration of the program quality due to the source modification to the online business processing program after the unit test and the inclusion of human error accompanying the modification.

Regarding this, "Computer Encyclopedia" by Akio Munekami (Asakura Shoten, 1988) 3

The description on page 189 can be referred to.

The present invention has been made in view of the above,
The purpose is to use a compiler on the development environment to properly and efficiently debug a program developed in a development environment different from the execution environment, based on the program description language specifications on the execution environment. It is to provide a method of matching a program source code that matches a developed program with a compiler specification on a development environment.

[0012]

In order to achieve the above object, the program source code matching method of the present invention uses a compiler in a development environment different from the execution environment in which the program actually operates, in the execution environment. A program source code matching method for matching a program developed based on a program description language specification with a compiler specification on a development environment, and checking whether the program is source coded according to the program description language specification. Corrective means to check and correct so that if it does not comply with the program description language specifications,
Matching information storage means for storing matching information between the program description language specification and the compiler specification on the development environment; and a matching target source code for the source program modified by the modifying means based on the matching information. The gist is to have a matching means for matching the detected matching source code with the compiler specifications on the development environment.

[0013]

According to the program source code matching method of the present invention, the source program created on the development environment is checked and modified based on the program description language specifications, and the matching target source is based on the matching information from the modified source program. The code is detected and the detected matching source code is matched with the compiler specifications on the development environment.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a program source code matching system according to an embodiment of the present invention. The matching method of the program source code shown in the figure is, for example, UNIX as an example of an online business processing program used in an execution environment of a large-scale general-purpose computer 6
-Development based on the use of the program description language in the execution environment while using the compiler in the distributed development environment consisting of WS10 to create a source program of the online business processing program, and to create the source program of the created source program. In order to perform a unit test such as debugging for the online business processing program, the matching target source code of the online business processing program is calculated based on the matching information which is the difference between the program description language specification on the execution environment and the compiler specification on the distributed development environment. A support tool for analyzing / designing the target business of an online business processing program, which is designed to match the compiler specifications on the development environment 1
1, an editor 1 used to create a source program for an online business processing program, a file storage area 2 for storing the source program of the created online business processing program, a program description language specification on the execution environment and a distributed development environment The matching information that is the difference from the above compiler specification is stored, the matching target source code of the source program of the online business processing program is detected based on this matching information, and the detected matching target source code is used in the development environment. It is composed of a program source code matching tool 3, a compiler 4, and a symbolic debugger 5 which are matched with the compiler specification of.

Further, the file storage area 2 is a pre-conversion online business processing program source file 21,
Post-conversion online business processing program source file 2
2. The online business processing program object file 23 is included, and the program source code matching tool 3 includes a check unit 31, a matching information unit 32, a converting unit 33, and an MMI unit 34. In addition,
In FIG. 1, the solid line shows the flow of control and the dotted line shows the flow of data.

Next, the overall flow will be described with reference to the flow chart shown in FIG.

First, the target business of the online business processing program is analyzed and designed (steps 100, 20).
0), and then source coding is performed using a compiler on the distributed development environment to create a source program (step 300). When the source program is created, its unit test is performed using the symbolic debugger 5 (step 400). Note that step 300,
The process of 400 will be described in detail with reference to FIG.

When the unit test in the distributed development environment is completed, the source program whose test has been completed is transferred to the large-scale general-purpose computer 6 in the execution environment, and the integration test and comprehensive test are performed (steps 500 and 600).

Next, the processing in steps 300 and 400 will be described in detail with reference to the flow chart shown in FIG.

The online business processing program developer uses the editor 1 to code the online business processing program to create a source program, and temporarily stores it in the pre-conversion online business processing program source file 21 in the file storage area 2 (step 310).

Next, the program source code matching tool 3 is activated, the source program in the pre-conversion online business processing program source file 21 is input, and the source code of the program is checked by the check unit 31 to be the online business processing program description language. It is checked whether or not it conforms to the specifications, and the check result is displayed on the screen or output as a list via the MMI unit 34 (step 32).
0).

According to the check result, the online business processing program developer repeats the correction of the source code using the editor 2 as necessary until the check is OK (steps 330 and 340). Check OK
When it becomes, the check unit 31 notifies the online business processing program developer of the check OK through the MMI unit 34, and the source program is converted to the pre-conversion online business processing program according to the instruction of the online business processing program developer. After storing in the source file 21, control is passed to the converting unit 33 (step 350).

The converting unit 33 automatically detects the source code to be converted from the source program in the pre-conversion online business processing program source file 21 on the basis of the matching information set in the matching information unit 32 in advance. The code is automatically converted, the converted source program is stored in the converted online business processing program source file 22, and the processing is terminated (step 360).

In order to carry out a unit test of the online business processing program, the developer of the online business processing program activates the compiler 4 to compile the source program stored in the converted online business processing program source file 22, The object of the online business processing program is generated and stored in the online business processing program object file 23 (step 370), and subsequently the symbolic debugger 5 is activated to target the online business processing program object in the online business processing program object file 23. As a unit test (step 40)
0). The above procedure is repeated as necessary until the test result is OK (step 410).

When the online business processing program is transferred to the execution environment due to the completion of the test, the source program stored in the pre-conversion online business processing program source file 21 is directly transferred via the storage medium or the communication line ( Step 420).

According to the above embodiment, by using the program source code matching tool 3 in the distributed development environment, it becomes unnecessary to manually modify the source code,
It is possible to avoid deterioration of work efficiency and program quality.

In addition to improving the efficiency of online business processing program development, there are the following advantages.

By registering the conversion information corresponding to the combination of the specifications of the compiler of the development environment to be used and the specifications of the online business processing program description language in the matching information section 32, the source code can be matched to any combination of the specifications.

The input and output interfaces of the program source code matching tool 3 can be used in combination with any editor and any compiler by adopting a standard source format, and independence from the vendor tool can be secured. it can.

By programming the program source code matching tool 3 itself by the standard C and the function independent of the processing system, independence from the WS model of the development environment can be secured.

In the case of COBOL description online business processing program development, since the compiler on the current WS does not support Japanese, messages such as compile errors are displayed in English. There is a problem in terms. However, if the check unit 31 is used, errors such as coding errors detected in the compilation work are checked out, and the check result and the like are output in Japanese, so the source can be easily corrected according to the check result. In addition, since it is usually unlikely that a compile error is detected in the check-OK source program, it is possible to avoid a reduction in work efficiency due to the compiler's lack of Japanese support.

It is needless to say that the above embodiment is an embodiment of the present invention and the present invention is not limited to this.
