Abstract

PURPOSE:To easily control the processing flow by providing a means which decides the processing operations to be successively carried out after obtaining the position of a head address and by reference to a processing address table. CONSTITUTION:A processing execution control table evolving means 6 reads the contents of a processing execution control table file out of an auxiliary storage 5 and evolves the contents to a processing execution control table 4 of a load module 1. A processing decision means 7 obtains the position of a head address based on the contents of the table 4 evolved by the means 6 and decides the processing operations to be successively carried out by reference to a processing address table 3. At the same time, a processing execution means 8 carries out successively the processing operations included in a processing group 2 decided by the means 7. Thus the processing flow can be easily changed to the module 1 with change of the contents of the table 4.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program control method, and particularly to a program control method for controlling the flow of processing for an executable program of an information processing device.

[Conventional technology]

In conventional program control methods, in order to change the flow of processing for a load module, which is an executable program, the source program must be modified, compiled and linked again, and a new load module created. .

[Problem to be solved by the invention]

In the conventional program control method described above, in order to change the flow of processing for a load module, the source program is modified, compiled and linked again, and then
Since the load module is newly created, it has the disadvantage that it takes a long time to compile and link.

An object of the present invention is to provide a program control method that can change the flow of processing for a load module simply by changing the contents of a processing execution control table without compiling or linking.

[Means to solve the problem]

A program control method according to a first aspect of the present invention is a program control method for controlling the flow of processing for a load module, which is an executable program of an information processing device, wherein: (A) the flow of the program is subdivided according to various conditions; a processing group on the module, (B) a processing address table on the load module that enumerates and stores the start address of each of the subdivided processes in the processing group, and (C) corresponding to each of the processes to be started sequentially. (D) a processing execution control table on the load module that holds each of the positions of the start addresses stored in the processing address table; (D) an auxiliary device that stores each of the processing execution control tables as a processing execution control table file; a storage device; (E> processing execution control table development means for reading the contents of the processing execution control table file from the auxiliary storage device and developing it in the processing execution control table on the load module; (F) the processing execution control (G) a process determining unit that obtains the position of a start address according to the contents of the process execution control table expanded by the table expansion unit and determines processes to be sequentially executed by referring to the process address table; The processing execution means sequentially executes the processing in the processing group determined by the processing determination means.

Further, the program control method of the second invention is a program control method for controlling the flow of processing for a load module, which is an executable program of an information processing device, (A) subdividing the flow of the program according to various conditions in advance. By preparing various types of processing, forming a processing group on the load module, and enumerating and storing the start addresses of each of the subdivided processes in the processing group, A processing address table is provided, and (B) a processing execution control table file is provided for each processing execution control table that holds each of the positions of the start addresses stored in the processing address table, corresponding to each of the processings to be sequentially activated. (C) reading out the contents of the processing execution control table file from the auxiliary storage and developing it as the processing execution control table on the load module; (D) storing the expanded processing in the auxiliary storage; Obtain the position of the start address according to the contents of the execution control table, determine the processes to be executed sequentially by referring to the process address table, and (E) sequentially execute the processes in the determined process group. It is made up of the following:

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the program control method of the present invention.

As shown in FIG. 1, the program control system of this embodiment controls the flow of processing for a load module 1, which is an executable program of an information processing device.

First, processing group 2 on load module 1 includes various processing A that subdivides the flow of the program according to various conditions.
It has B, C,...

In addition, the processing address table 3 on the load module 1
is subdivided treatment A within treatment group 2.

The starting addresses of B, C, . . . are listed and stored.

On the other hand, the process execution control table 4 on the load module 1 holds each of the positions of the start addresses stored in the process address table 3, corresponding to each process to be started sequentially.

On the other hand, the auxiliary storage device 5 stores each of the processing execution control tables 4 as a processing execution control table file.

Therefore, the processing execution control table expansion means 6
The contents of the processing execution control table file are read from the auxiliary storage device 5 and expanded into the processing execution control table 4 on the load module 1.

Then, the processing determining means 7 obtains the position of the start address according to the contents of the processing execution control table 4 expanded by the processing execution control table expansion means 6,
By referring to the processing address table 3, the processing to be executed sequentially is determined.

Further, the process execution means 8 sequentially executes the processes in the process group 2 determined by the process determination means 7.

〔Effect of the invention〕

As explained above, the program control method of the present invention is
You can change the processing execution order and conditions simply by changing the contents of the processing execution control table without compiling or linking, so it has the effect of easily changing the processing flow for load modules. are doing.

As a result, the program control method of the present invention can reduce the number of man-hours involved in modifying, compiling, and linking source programs when the execution order or conditions of processing are changed. This has the advantage that even if an error in the execution order or conditions occurs and is discovered after the program is completed, it can be easily corrected.
