Abstract

PURPOSE:To form a programs to be used in different kinds of machines as common programs by separately controlling a part of a source program which depends upon the characteristics of computer architecture operating systems and the other independent part. CONSTITUTION:The part of a program body X which is independent of the characteristics of computer systems a1-an is described as it is by using normal programming language and the program part depending upon the characteristics of the systems a1-an is described and formed by indexing name lists A, B. A program synthesizing part 5 outputs a source program S1 for a program to be operated on the system a1 and an output device 4 receives the source program S1 and stores or prints out the received contents in a magnetic disc device 41 or printer device 42. The program part common to the systems a1-an, i.g. the program body X, can be changed by changing only the program body X stored in the 2nd storage part 2. Namely, the program body X can be changed by changing only one file.

Description

[Detailed description of the invention] (Industrial application field) Concerning source program management methods.

(Prior Art) Conventionally, as a management method for source programs such as application programs written in high-level programming languages, source programs are created to correspond to different characteristics of the applied computer system architecture and operating system. I manage each money I create.

The difference between the source programs prepared in this way is only in the description of the computer architecture and operating system characteristics, and most other program description parts are the same. Therefore, in the conventional source program management method, if a change occurs in most of the above common program description parts, the entire managed source program must be changed, which affects the maintainability, reliability, and portability of the program. The problem is that it is inferior.

(Problems to be Solved by the Invention) An object of the present invention is to separate and manage parts of a source program written in a high-level programming language that depend on computer architecture operating system characteristics from parts that do not. Provides a source program management method that has only one common part that does not depend on architecture or operating system characteristics, and eliminates problems with conventional management methods such as program maintainability and reliability. It is intended to be used as a top priority.

(Means for Solving the Problems) The method of the present invention provides an input means for inputting program money in a method for managing source programs of a plurality of computer systems having different characteristics, including a program part that depends on the characteristics of the computer system. and a tenth storage means for storing each of the plurality of computer systems with all program part names inputted from the input means depending on the characteristics of the computer system corresponding to each of the plurality of computer systems; a second storage means for storing the main body of the source program, which is formed by quoting a program part depending on the characteristics of the computer system inputted from the input means by the name; read out the program main body from the second storage means, and all the quoted parts by the name are given the same name as the name of the quoted part corresponding to the instruction in the tenth storage means; characteristics of the computer system; program synthesis means for reading out and replacing program parts that depend on the program to synthesize a source program, and supplying the source program synthesized from the program synthesis means? and output means for outputting the output to the outside.

(Example) Next, an example of the present invention will be described with reference to all the drawings.

FIG. 1 is a block diagram showing one implementation of the present invention. The source program management system shown in FIG. 1 is related to an input device 1 for inputting a program, a second storage unit 2 for storing program bodies x6, which will be described later, among the input programs, and characteristics of the computer architecture and operating system. A file 3 that stores description parts, for example, part A and part B described later, for each computer system to which it is applied.
The program main body Xi is read from the 10th storage unit 3 consisting of -1 to 3-n and the second storage unit, and the partial person and part B read from the specified file of the storage unit of VCgl are synthesized. The apparatus is composed of a program synthesis section 5 that performs the program synthesis, and a magnetic disk device 41 and a printer device 42 that output all of the synthesis programs supplied from the program synthesis section 5.

As an example, management of source programs for n computer systems a1 to an having different computer architectures and operating system characteristics will be explained.

Considering that there are generally multiple program parts that depend on the characteristics of the computer systems a1 to an, the program prepared prior to the application of this embodiment has a large number of parts, for example, parts A and B and the program main body X. Created separately.

Program parts A and B are computer systems a1 to an
The contents are A4~An, B1~Bn, respectively.
Although they are different from each other, a common name A{i- is given to AI=An, and a common name B is given to B1 to Bn.

The program body Xt-t and the parts that do not depend on the characteristics of the computer systems 81 to an are written as they are using normal programming language sounds, and the program parts that depend on the characteristics of the computer systems 81 to an are written using the above-mentioned names A and B. Create a document by quoting it.

Next, the operation of this embodiment will be explained.

First, the program body x2 is manually inputted from the input device 1 and stored in the second storage section 2Vc. Next, from input i[1, a total of n systems a1 to anVC-dependent program parts A4 to An
, B1 = Bn f is input to the computer system↓ and stored in a file in the 10th storage section of each VC. That is, for example, the program part Al for the computer system a1, the BIU file 3-1, the computer system an
The program parts An and Bn for Ic are in file 3-
Store in n. In each file, the same names A and B are given as described above.

When creating a source program 81'e for a program that runs on a certain computer system, for example al, upon receiving an instruction to create the source program S1 input from the outside, the program synthesis unit 5 corresponds to the 10th storage i computer system a1. Select all files 3-1 and read the program main body X from the second storage unit 2, and select the program part A1 corresponding to the cited name of the program part depending on the characteristics of the computer system, for example, A. Then, extract it from file 3-1 and replace it with the quoted part.

In this way, the program synthesizing unit 5 outputs the source program S1' of the program running on the computer system A1 as a result, and the output device 4 receives this and stores it in the magnetic disk device 41 or outputs it to the printer device 42. Or print it out.

When changing the program part, that is, the program body X that is common to the computer systems a1 to an, it is only necessary to change the program body X stored in the second storage section, and this can be done by changing only one file.

(Effects of the Invention) According to the present invention, it is possible to unify common programs in programs created in a high-level language and run between different models, and the maintainability, reliability, and portability of the common programs can be improved.
