[Conventional technology]

As is well known, when a program is executed by a computer, the program must be a module of the program called a load module. The load module is composed of a program converted into a code string of a predetermined type that can be immediately executed when loaded into the main memory, and required control information.

The load module is generated by a well-known link process. In the link process, a target program module generated by a translation process from a source program described by a program creator is input as required by a control statement, and a plurality of target program modules are required. And performs processing such as address information, as a load module, and outputs it with a specified name. The control statement specifies the module name, load module name, output destination, and the like of the target program module.

FIG. 4 is a block diagram showing a configuration example of a computer. When link processing is performed, control statements 2 and
The target program 4 is stored in the program storage file 3 and the link processing unit 5 is started. The link processing unit 5 reads the control statement 2 in the specified control statement file 1, executes the link processing for the specified target program module 4, outputs the load module 7 to the load module file 6, and ends the processing. .

FIG. 5 is a diagram showing an example of the processing flow of the link processing unit 5. When the link processing unit 5 is started, the control statement file 1
Is opened, and the control statement 2 is read in the processing step 11.

As a result, the necessary program storage file 3 is opened in the processing step 12, and the load module file 6 for outputting the load module is opened in the processing step 13.

After the above, the link processing is executed in the processing step 14, a load module is generated from the target program module 4 read from the program storage file 3, and output to the load module file 6 as the load module 7. When the processing is completed, each file is closed in processing step 15.

When the processing for generating one load module is completed by the above processing and the continuous processing is identified in the processing step 16, the processing step 10 is performed for each load module generation.
It repeats from processing of.

[Problems to be solved by the invention]

In the development of a program system, particularly in system maintenance, it is often necessary to generate load modules for many programs at once. According to the link processing, the open / close processing of the input / output file is executed for each load module even in such a case, which contributes to a longer processing time.

An object of the present invention is to provide a link processing device capable of improving the processing efficiency of link processing by sequentially and collectively generating a plurality of load modules.

[Means for solving the problem]

 FIG. 1 is a block diagram showing the configuration of the present invention.

The figure shows the configuration of the link processing device, and the control statement file
20 is a computer device that performs a process of generating a predetermined load module from the program of the program storage file 21 according to 20, including a delimiter identification unit 22 and a link processing unit 23, and the control statement file 20 includes a predetermined Each of the first delimiter records 20 is composed of the first delimiter record 24 and the control statement 2.
Has a predetermined identifier, and stores the program storage file 21.
Consists of a predetermined second delimiter record 25 and a target program module 4. Each second delimiter record 25 has a predetermined identifier. For each delimiter record 24, the first delimiter record 24 and the control statement 2 following the first delimiter record 24 are read out until a predetermined end of the control statement is detected. The target program module 4 stored following the second delimiter record 25 having the same identifier as the identifier held in the read first delimiter record 24 is read out until a predetermined end of the program is detected. The process of passing the read control statement 2 and the target program module 4 to the link processing unit 23 for each first delimiter record 24 is performed at the beginning of the control statement file 20. From the first delimiter record to the last first delimiter record, the link processing unit 23 sequentially executes, for each of the read target program modules passed by the delimiter identification unit 22 for each first delimiter record, A load module 7 is generated by executing a link process according to the read control statement. [Operation] By the link processing device of the present invention, a plurality of control statements and objects separated by a delimiter record corresponding to a plurality of load modules are provided. Since the program modules are collectively processed into one file, the process of generating a group of a plurality of load modules can be performed by the open and close processes once for each of the required three files. The target program module has been processed into one file for each. Also, it is possible to improve the overall process efficiency.

〔Example〕

The first delimiter record 24 in FIG. 1 has, for example, a format as shown in FIG. 2 (a), and includes a keyword indicating that the record is a delimiter record and an identifier. Use the numbers shown.

The second delimiter record 25 is, for example, as shown in FIG.
In the format as shown in the figure, the identifier of the present invention is added to the first block of the control information at the front of the target program module. .

In FIG. 1, a delimiter identification unit 22 is used for link processing.
