Abstract

PURPOSE:To facilitate the production of a source program which may sometimes include the Japanese character codes with use of an editing process function for Japanese word documents by describing a specific language identifier at the head of each described sentence except the commentary sentences. CONSTITUTION:A normal Japanese word processor uses a Japanese word dictionary 14 produced by a Japanese word document production processing part 12. Then a source program is produced as a Japanese word document 16 by means of the processing function of the Japanese word processor. A language identifier is set at the head of each described sentence except the commentary sentences in accordance with the applied system. A source form conversion processing part 13 converts a sentence containing a language identifier into a character code and stores the result of this conversion into a source program file 17 as a source program 18. Thus it is possible to easily produce the program 18 which includes the program character codes and the Japanese character codes mixed together.

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention relates to a source program creation processing method for creating a source program in a computer language such as C0BOL in which annotation sentences can be written in Japanese characters in a computer system.

The purpose is to make it possible to easily create a source program that may include 9 Japanese character codes using a Japanese document editing function.

For the effective line of the program, set the character code of a specific language identifier among multiple predetermined language identifiers at the beginning, and write the source program using the Japanese character code using the 1 Japanese document creation process. Then, the document creation processing process that creates the document file, and each line of one document file is input, and if there is a character code for the specified language identifier at the beginning, that line is used to input the character code system that should be used to write the program. and a source format conversion processing step for converting into a character code string and outputting it to a source program file.

[Industrial application field]

The present invention relates to a source program creation processing method for creating a source program in a computer language such as COBOL, in which annotation sentences can be written in Japanese characters, in a computer system.

Although alphanumeric characters are generally used in programming languages to write instructions for operating computers, annotations (comments) in Japanese are inserted into the source program to make it easier to understand the contents of the source program. things are being done.

A means for easily inputting Japanese sentences is desired.

(Conventional technology) FIG. 4 shows an example of the prior art.

In the figure, 10 is a processing device, 11 is an input device, 14 is a Japanese dictionary, 17 is a source program file 18 is a source program, 40 is an input switching unit that switches input of alphanumeric code and Japanese character code in units of l hide; 41 is a Japanese character code input section, 42 is an input buffer, 43 is an editor for editing the source program 18, 44 is a compiler, and 45 is an object program that translates the source program 18 into machine language.

When creating a source program 18 using the C0BOL language or the FORTRAN language TR, an editor 43 is used which normally has a two-line editing function.

It is used. The editor 43 inputs characters from the input device 11 such as a keyboard, and outputs records of each line to the source program file 17.

By the way, if the annotations in the source program 18 are written in Japanese characters using Kanji or Kana characters, the program becomes much easier to read. However, in general, character codes used to write alphanumeric programs are 1-byte alphanumeric codes, and Japanese character codes, which are handled in 2-byte units, cannot be directly input using the existing editor 43. .

Therefore, conventionally, a single Japanese character code input section 41 is prepared separately from the editor 43 as shown in FIG.
You can switch between inputting Japanese character codes and inputting alphanumeric codes in 1-byte units, and add alphanumeric codes and 1 byte to the program.
I tried to mix it with Japanese character code.

That is, when there is a designation to input one Japanese character, the one Japanese character code input section 41 uses the one Japanese dictionary 14 to perform kana-kanji conversion, etc., and stores the conversion result in the input buffer 42. The editor 43 is.

The contents of the input buffer 42 are output to the source program file 17.

(Problems to be Solved by the Invention) In particular, the purpose of use of the data section area in a program is determined in advance, and it is frequently referenced during program creation and maintenance. For this reason, it is being promoted to write annotations in the data section, etc. in one Japanese language, but according to the conventional technology, as shown in FIG. Access 1
There was a problem in that Japanese character codes had to be imported character by character. Therefore, there was a problem in that the input operation was complicated and took three hours.

In addition, for example, in the development of a cross compiler that separates objects that operate on multiple systems, it is naturally necessary to write programs with each operating system (O3) in mind. In the definition of the data section, although the purpose of use is the same, there are many cases in which the size and format of the area are different. In this case, considering the purpose of use, it is desirable to combine the files into one file.

However, in the past, it was necessary to deal with each computer and operating system individually.

The present invention aims to solve the above-mentioned problems and to make it possible to easily create a source program that may include Japanese character codes by using a Japanese document editing function. There is. It also aims to provide a means for easily developing a cross compiler.

[Means to solve the problem]

FIG. 1 shows an example of the configuration of the present invention.

In FIG. 1, 10 is a processing unit consisting of a CPU and memory, 11 is an input device such as a keyboard, 12 is a Japanese document creation processing unit that has the processing function of a Japanese word processor, and 13 converts character codes, etc. a source format conversion processing unit; 14 a Japanese dictionary having a correspondence table between input code strings from the input device 11 and Japanese character codes; 15 a document file; 16 a Japanese document; 17 a source program file; Represents a source program.

Further, PL represents a document creation process, and P2 represents a source format conversion process.

When creating the source program 18, which may include a Japanese character code different from the character code system used to describe the program's data or command statements as the character code used in the comment statement.

In the present invention, one document is created by a document creation process P1 and a source format conversion process P2.

In the document creation process P1, the character code of a specific language identifier from among multiple predetermined language identifiers is set at the beginning of the effective line of the data statement or instruction statement of the program, and 1 Japanese document creation process is performed. , a source program is written using Japanese character codes, and a document file 15 thereof is created. The language identifier is @,! ,%,・
This is a predetermined symbol depending on the system to which the source program is applied.

In the source format conversion process P2, 9 document creation process P
Input each line of the document file 15 created in step 1, and if there is a character code of the specified language identifier at the beginning, convert that line to a character code string of the character code system to be used for writing the program, and The line is output to the source program file 17 as a comment line.

[Effect]

In the present invention, a source program is created as a Japanese document 16 by using the processing function of a normal Japanese word processor using a Japanese dictionary 14 by a Japanese document creation processing section 12. At this time, a language identifier corresponding to the system to be applied is set at the beginning of the descriptive text other than the annotation.

Next, the document file name of 9 document file 15.

Specify the set language identifier 1, for example "@".

When the source format conversion processing unit 13 is started, the source format conversion processing unit 13 converts the sentence with the language identifier @ to E
Convert to character code to be used for writing programs such as BCDIC code. and.

The conversion result is stored in the source program file 17 as the source program 18.

As a result, the source program 18 of the program in which the character code for the program and the two Japanese character codes are mixed.
2) can be created using a Japanese word processor, etc., and 1. A source program can be easily created using the copying, moving, and other editing functions of the Japanese word processor.

By using multiple types of language identifiers.

The Japanese document 16 that is the source of the source program 18 suitable for various systems can be managed by one document file 15.

〔Example〕

FIG. 2 shows an embodiment of the present invention, and FIG. 3 shows a processing flow according to an embodiment of the present invention.

An example of creating a COBOL registry according to the present invention will be described with reference to FIG.

The C0BOL Registry is the C0BOL program.
This is a collection of descriptions of data definition areas developed by the copy command.

First, the Japanese document creation processing unit 12 creates a Japanese document 16 as shown in FIG. 2 in which annotation sentences are written in Japanese. This Japanese document 16 can be created using the processing functions of an existing Japanese word processor. For text other than comment text, write the language identifier determined depending on the system at the beginning. This language identifier depends on the language.

For example, there are the following.

@: C0BOL (For System 1 - 16 bit machine): C0BOL (For System 2 - 32 bit machine) #: C language &: Assembler %: Invalidate this line /: Page break specification in C0BOL,...・・・
Note that various other language identifiers can be defined.

When starting the source format conversion processing section 13.

Specify the language identifier depending on the language and system.

``If you specify @j, C0BOL Registry 2 shown in Figure 2 will be displayed.
In the 2 Japanese document 16 like 0-1, the character code is converted so that the data definition statement with @ is valid, and a sequential file of the COBOL registry for the system 1 is created.

On the other hand, if you specify "!" when starting up the source format conversion processing unit 13, in one Japanese document 16 like the COBOL registry 20-2, ! Character code conversion is performed to enable data definition statements with
A sequential file of the OL registration collection is created.

The C0BOL program 21 that has taken in the source from this C0BOL registry 20-1 or the C0BOL registry 20-2 by the copy instruction is run by the C0BOL compiler 2.
By compiling with 2, it is possible to create an object program suitable for the system.

Since the processing performed by the Japanese document creation processing section 12 can utilize the processing functions of a conventional Japanese word processor, etc., an example of the processing performed by the source format conversion processing section 13 will be described in particular with reference to FIG.

In the following explanation, ■ to [phase] are the processes shown in Fig. 3.
~ Corresponds to [phase].

■ First, through conversation processing, the document in which the program is written, the file name, and the language identifier are input.

■ Next, read one line of the specified document file into the memory work area.

■ Determine whether the records in the document file are finished. If completed, move on to process ■.

■ Check whether a half-width identifier (shift order) that specifies half-width characters exists in the read one-line record.

■ If there is no half-width identifier, skip the ninth step ■.

■ Remove half-width identifiers in the work area.

Pack internal data.

■ Store one line of data in the work area into one work file. After that, control is returned to processing ■.

Repeat the process in the same way.

- When the document file is finished, close the 9th work file (hereinafter referred to as the first work file), re-open it, and repeat the following process.

■ Read one line of the first work file into the work area in memory.

[Phase] Determine whether the first character of one line matches the language identifier specified in the conversation process of process (■). If they do not match, proceed to process ■.

(2) If they match, convert the line from a double-hide Japanese character code to a program character code such as a 1-byte EBCDIC code in order to make the line a valid line for a program that is not a comment statement.

@ Determine whether the recording of the first work file is finished. If finished, move to process [phase].

■ Store one line of data in the work area in memory in another work file (second work file). after that,
Return control to process ■ and repeat the process.

[Phase] When the recording of the first work file is completed, the contents of the second work file are copied to the read-out file. Through this copying, the variable-length file is converted into a fixed-length sequential file format, and a file that can be handled by various language processing units is created.

(Effects of the Invention) As explained above, the present invention provides the following effects.

(1) Annotations can be written freely using the processing functions of existing Japanese word processors, etc.

You can now easily write tables, etc., which were difficult to do with conventional editors.

(2) In the development of a cross compiler (written in COBOL or the like), data definition areas (COB'OL registry) that differ for each system can be compiled into one document. Based on the name, the description of the data definition area can be incorporated into the program according to the system, making it easier to manage the data definition area.

(3) B main score input processing can be performed at high speed without switching inputs, improving operability and improving work efficiency.
