Abstract

PURPOSE:To attain the operation of a source program only and to shorten the developing time by identifying the additional information part of the assembly list information and the source program part and processing the contents of an operating instruction received from a console based on the position of a cursor. CONSTITUTION:The source program information is identified together with the additional information on the row Nos, the addresses, the machine word codes, the titles, the error messages, the macro evolving rows, etc., contained in the assembly list information to be inputted. Then only the source program part is processed. Thus the additional information part is deleted at output of a file, and only one input file is repetitively required. As a result, the processing time is shortened. Therefore a file editing device 10 consists of an input 11 inputted from the file 21, a key input part 12 which inputs keys via a console 22, an editing part 13 which edits the assembly list based on the input keys, a console output part 14 which outputs the editing result to the console 22, and an output part 15 which outputs the editing result to an output file 23.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is used in a file editing device using an information processing device, and particularly relates to a file editing device for editing assemble list information.

〔overview〕

The present invention provides a file editing device that inputs assemble list information including additional information and source program information, performs specified editing, and generates and outputs a source program. The program development time can be shortened by identifying the source program information, making it possible to manipulate only the source program information, and deleting additional information when outputting a file.

[Conventional technology]

In developing and modifying programs, not only the developed source program but also an assemble list containing additional information such as line numbers, addresses, machine language codes, titles, error messages, and macro expansion fragments is required.

The assemble list is created by an assembler to obtain the additional information that is necessary for developing a program. Also, at this time, the assembler writes
Although object information is also obtained, it is not related to the input/output information of the assembler list file editing means of the present invention, so it will be omitted.

A conventional program development method will be explained with reference to FIG.

In developing a program, when correcting an error in a source program, first, the source program 70 is input to the assembler 50, and an assemble list 80 output from the assembler 50 is obtained. In order to correct the error message, which is additional information in the assemble list 80, the source program 70 is manually input to the file editing device 60, the error location is found, the error location is corrected, and as the editing result, Update the source program 70 and use the assembler 5 again.
The process of inputting 0 was repeated.

[Problem to be solved by the invention]

Although an assemble list containing additional information such as error message information is necessary for program development and modification, the list manually entered into the assembler must not contain any additional information.

Therefore, in the conventional program development described above, as shown in FIG.
There are two files to be processed: the first is the source program 70, and the second is the source program, as well as line numbers, addresses, machine language codes, tight novel error messages, and macros. This is an assemble list 80 that includes additional information such as expanded pieces. In program development, these two files, the source program 70 and the assemble list 80, must be managed and updated, which has the disadvantage that program development is complicated and processing time is long.

An object of the present invention is to provide a file editing device that can easily develop programs in a short processing time by eliminating the above-mentioned drawbacks.

[Means to solve the problem]

The present invention includes an input section for inputting additional information and source program information generated by an assembler from an input file, a key input section for inputting operation instruction information from a console, and a key input section for inputting operation instruction information from a console. In the file editing device, the editing section includes an editing section that edits assembled list information, a console output section that outputs editing results to the console, and an output section that outputs the editing results to an output file. an identification section that includes a specification section, a title line keyword specification section, an error line keyword specification section, and a macro expansion keyword specification section, and identifies the additional information and the source program information from the manually generated assemble list information; and the created source. The present invention is characterized in that it includes a deletion unit that deletes the additional information portion when outputting the program to the output file.

[Effect]

The identification section identifies additional information (line numbers, addresses, machine language codes, titles, error messages, macro expansion pieces, etc.) in the input assemble list information and source program information, and only identifies the source program information part. The deletion unit deletes the additional information part when outputting the file to obtain a source program.

Therefore, in the process, only one file, which is manually required, is required repeatedly, and the processing time can be shortened.

As information for identification, a column number specification section 3 and a title row keyword specification section 4 are provided.
, an error line keyword specifying section 5, and a macro expansion piece keyword specifying section 6.

It is assumed that the file editing device 10 of this embodiment manually inputs character by character from the key input unit 12 and processes the assemble list of the input file 21 character by character.

FIG. 2 is an image diagram of the assemble list 30 of the input file 21 created by the assembler.

The assemble list 30 includes additional information such as line numbers, addresses, and machine language code in the left half, and additional information on macro expansion pieces and the source program in the right half, and the error line is included in one line on the left and right sides. There is.

FIG. 3 is an explanatory diagram showing the program development procedure in this embodiment. In this embodiment, the file editing device IO uses the identification section 1 and the deletion section 2 to use one assemble list 30 shown in FIG.
It is input to the assembler 50 and processed.

In this embodiment, the 1st to 40th columns of the assemble list 30 are line numbers, addresses, and machine language code additional information, and the 41st and subsequent columns are macro expansion piece additional information and source program. shall be. Therefore, the column number specifying section 3 has a column number 40 that separates the additional information of the line number, address, and machine code, the additional information of the macro expansion piece, and the source program. In addition, in this embodiment, the title line keyword specification unit 4 has rTITIJ J as a keyword for determining whether or not it is a title line, and the error line keyword specification unit 4 has rTITIJ J as a keyword for determining whether or not it is an error line. Part 5 has the head office RRORJ, and judges whether or not there is a keyword in the character string from the first column, and further includes a macro expansion piece keyword specification part as a keyword to judge whether there is a macro expanded line or not. 6 has rMJ, and it is determined whether the keyword is present in the 39th column, which is the specified number of columns minus 1.

The user looks at the assemble list 30 to which the error message has been added, and uses the error message to correct the error location in the source program portion of the assemble list 30. At this time, the column number specification 83, title line keyword specification section 4, error line keyword specification section 5, and macro expansion piece keyword specification section 6 in the identification section 1 each provide column number information as information for identification. , title line keyword information, error line keyword information, and macro expansion side keyword information, it is possible to modify only the source program part of the assemble list 30, and by mistake, line numbers, addresses, and machine language as additional information may be modified. Code, titles, error messages, and macro expansion fragments are not modified. This will be explained in detail below.

FIG. 4 shows the editing section 1 of the file editing device 10 of this embodiment.
3 is a flowchart showing the processing procedure in the identification unit 1 of No. 3;

Operation information input from the console 22 through the key input section 12 is processed in the identification section 1 in the following procedure.

Operation information input processing step S1 reads one input character or cursor movement code.

A cursor movement code determination processing step S2 determines whether or not the read character is a cursor movement code, and if it is a cursor movement code, a cursor movement code processing step S3 is performed.

If it is not a cursor movement code, it is sequentially determined in the next four processing steps S4 to S7 whether or not the current cursor position is in the additional information portion. First, in column position determination processing step S4, it is determined whether the number of columns at the current cursor position is less than or equal to the 40th column of the column number specifying section 3.
If it is below the 0th column, the operation information manual processing step S
Ignore the characters entered in 1. Next, in the case of the 41st column or more, in title line determination processing step S5, it is determined whether the character string from the first column at the current cursor position is rTITLB J of the title line keyword specification section 4. However, if it is this keyword, the characters input in operation information input processing step S1 are ignored. Next, if it is not a title line keyword, in error line determination processing step S6, the character string from the first column at the current cursor position is
If it is this keyword, the characters input in operation information input processing step S1 are ignored. Next, if it is not an error 4 keyword, in step S7 of the macro expansion piece determination process, the 39th character at the current cursor position is "M" in the macro expansion piece keyword specifying section 6.
If it is this keyword, the characters entered manually in operation information input processing step S1 are ignored. Next, if it is not this macro expansion side keyword, the character at the current cursor position is input to the operation information manual processing step S1.
Process the characters entered in .

FIG. 5 is a flowchart showing the processing procedure in the deletion unit 2 of the identification unit 1 of the file editing device IO according to an embodiment of the present invention.

When a file output instruction is issued from the console 22 through the key input unit 12, the deletion unit 2 processes the file according to the following procedure.

The one-line input processing step Sll is the assemble list 30.
Read into the buffer until the line end code or file end code, which is the terminating character for one line, is reached.

Next, in four processing steps 312 to 515, the additional information portion is deleted. First, in character string length determination processing step 812, it is determined whether the length of the character string read into the buffer is 40 or less, and if it is 40 or less, the read character string is skipped. 41 or more, in title line keyword determination processing step 313, the character string at the beginning of the buffer is
It is determined whether TITLE J or not, and if it is that keyword, the character string in the buffer is ignored. If it is not the title row keyword, in error row keyword determination processing step S14, it is determined whether the character string at the beginning of the buffer is "ZERO BOND ERRORJ" of the error row keyword specifying section 5,
If that keyword is used, the string in the buffer will be ignored. If it is not an error 4 keyword, in pre-macro expansion keyword determination processing step 315, the 39th character from the beginning of the buffer, which is the number of columns minus 1 in the column number specification section 3, is entered in rMJ of the macro expansion piece keyword specification section 6. Determine whether the keyword exists or not, and if it is the keyword, skip the string in the buffer. If it is not a macro expansion side keyword, source program partial extraction processing step 316
Then, the character string starting from the 41st character is passed to the file output unit 15 and output to the output file 23. These processing steps 311-316 are repeated until the character string terminated with the file end code in processing step Sll is processed up to processing step 316.

Through the above processing, the input assemble list 30
3, only the source program portion shown in FIG. 3 is modified, and when outputting to the output file 23, only the source program portion is output as a file.

〔Effect of the invention〕

As explained above, the present invention identifies the additional information part of the assemble list information and the source program part, and processes the contents of the operation instruction from the console depending on the position of the cursor. By making only part of the source program operable without manipulating it, and by deleting the additional information part when outputting to a file, it is possible to obtain a source program that can be input into the assembler again. .

Therefore, compared to conventional development procedures, it is possible to reduce the number of files that are handled repeatedly into one file, which has the effect of shortening the program development time.
