[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program source conversion device used on an electronic computer.

[0002]

2. Description of the Related Art Generally, a program source conversion device used on an electronic computer is designed to reproduce the way the program operates on a starting point system at a position affected by the difference between the starting system and the target system. It has the purpose of conversion compensation.

However, the program source converted and supplemented by the program source conversion apparatus must be inspected in a quality assurance process, which is a later process, in the same way as if it was operating on the target system even on the target system. I have to.

Conventionally, in this type of quality assurance process, the data input by the program on the starting system is input again to the post-conversion program, and the output data as a result of the post-conversion program processing on the target system. Is stored and compared with the data output by the program on the starting system to check whether the same result is output. At this time, the comparison software automatically compares the output data on the starting system and the output data on the target system, and the human system judges the comparison result. At the time of the inspection, it is necessary to clarify where in the program the error began to occur if an incorrect result was obtained. The first clue here is to find out where in the program the incorrect result was output. Usually, the human system in this kind of program migration work is different from the personnel who created the program, so it is extremely difficult to investigate the problem.

[0005]

SUMMARY OF THE INVENTION The above-mentioned prior art is
In order to allow the comparison software to compare the output data processed by the converted program output by the program source conversion device and the output data on the target system that was saved, the migration work of the program is divided in time, There is a drawback that the connection between the output data and the processing of the program is lost.

An object of the present invention is to provide a program source conversion device capable of performing software migration work without losing the coupling between output data and the processing of the program.

[0007]

According to the program source conversion apparatus of the present invention, an output instruction portion in a program source is
It is provided with means for adding processing for comparing the data output by the program with the data output by the post-migration program on the origin system.

[0008]

Since the means for comparing the output data on the starting point system with the output data on the target system is incorporated in the converted program in advance, the worker does not make an effort to maintain the connection between the output data and the program processing. Complete.

Parsing is performed, the result is output to the lexical storage device 30,
The file / record information memory 14 also stores a lexical description that determines the file name, record length, and record layout. Conversion location search / conversion information output unit 12
Detects the end point of the file declaration from the lexical storage device 30, detects the location of the output instruction, and further stores the lexical elements constituting the file declaration passed from the file declaration lexical group generation unit 15 in the lexical storage device. 30 or the lexical group passed from the data input / comparison / judgment lexical generation unit 16 is inserted into the lexical storage device 30. The program source text generation unit 13 takes out the tokens that make up the program from the token storage device 30, forms a program source text, and stores it in the converted program source storage device 40. Based on the file / record information memory 14, the file declaration token group generation unit 15 generates a declaration token having output data on the origin system as an input file from the declaration of the output file of the program. The data input / comparison / judgment process The lexical generation unit 16 inputs “output data on the starting system, compares the input data with the output data of the post-migration program, and judges whether they are equal, If they are not equal, the output data is notified that the output result is different from that on the origin system. "A lexical group forming a command statement showing a series of processes is generated.

Next, the operation of this embodiment is performed by adding a process of comparing the data output by the program on the starting system with the data output by the post-migration program at the output command location in the program source. The apparatus 10 and the processing operation will be described with reference to FIG. 2 showing the structure of the pre-conversion program source and FIG. 3 showing the structure of the post-conversion program source.
