Abstract

PURPOSE:To prevent the mischange of an instruction sentence by discriminating an instruction dentence from a comment sentence included in a source program. CONSTITUTION:A central control unit CPU 1 which controls an editing system as a whole is connected to an instruction sentence/comment sentence discriminating module 2 which produces the information to discriminate an instruction sentence from a comment sentence included in a source program as well as to a comment sentence editing module 3 which refers to the discriminating information produced by the module 2 and accepts a source program editing request which is supplied with operation of an input/output device 4 including a display 41, a keyboard 42, etc., via buses respectively. In such constitution, it is possible to prevent automatically the occurrence of the mischange of the instruction sentence while only correcting the comment sentence of the source program.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a program comment statement editing system, and in particular to program comment statement editing systems 1 to 1 for adding, deleting, and replacing only comment statements in a source program. Regarding the system.

[Conventional technology]

Conventional programming and editing systems allow additions, reductions, and replacements using a screen editor, etc., without distinguishing between comment statements and instruction statements in a source program. It is also applied as is when you want to add, delete, or replace only comment sentences.

[Problem that the invention seeks to solve]

When adding, deleting, or replacing only a content statement using the conventional program editing system described above, there is a risk that the command statement may be erroneously changed due to an operational error or the like. For this reason, when adding or deleting comment statements or modifying a program that is already running stably in order to improve program readability and maintainability, it is necessary to reconfirm whether there are any erroneous changes to command statements. There are drawbacks that require testing.

The addition of comments 113 to improve the readability and maintainability of the program as described above is not necessarily carried out by the person who created the program, but may be entrusted to a third party, and the source There is a need for a comment editor system that can protect program instructions.

In order to solve the above-mentioned drawbacks, the present invention provides a program comment statement editing system that makes it impossible to change the command statements of the source program when adding, deleting, replacing, etc., comment statements to the source program. The purpose is to

[Means for solving problems]

The editing system of the present invention includes an identification means for generating information for identifying instruction statements and comment statements of a source program to be edited, and whether an input edit request is for only the comment statements. an editing means that determines whether the editing information is correct by comparing it with the identification information, and executes processing according to the editing request if the judgment result is positive, and prohibits processing according to the editing request if the judgment result is negative; , is equipped.

[Actual h&example]

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, a central control unit (hereinafter abbreviated as CPU) 1 that controls the entire system includes an instruction/comment statement identification module 2 that generates information for identifying instruction statements and comment statements in a source program; and the display 41. with reference to the identification information generated by the instruction/comment statement identification module 2. The comment editing module 3 is connected by a bus to a comment editing module 3 that accepts a source program editing request input through an operator of the input/output device 4 such as a keyboard 42.

FIG. 2 is a flowchart showing the operation of this embodiment.

In the same figure, step 202 indicates the operation of the instruction/comment statement identification module 2, and steps 203 to 207
indicates the operation of the comment text editing module 3. When started (step 201), under the control of the CPUI, the command/comment sentence identification module 2 first performs command/comment sentence identification processing to generate command/comment sentence identification information (step 2=02). Figure 3 is P
FIG. 4 is a data structure diagram illustrating a source program with a full program such as L, , / I, etc., and FIG. 4 is a data structure diagram illustrating instruction/comment statement identification information generated correspondingly. . In Figure 3, columns a and b are the start and end columns of statement 1, respectively, columns C and ( are the start and end columns of comment 1, and columns e and f are the start columns of statement 2. and end column, column g
and h indicate the start column and end column of comment statement 2, respectively. The instruction statement/comment statement identification information generated in response to this is used to display the start column and end column of instruction statements and comment statements in correspondence with each line number of the source program, as shown in Figure 4. If the program line number has a word and there is no command or comment statement, the word display in the start column and end column of that statement are both “oo”.
Make it.

In the source program edit request acceptance process (step 203) in FIG. In step 204), it is determined whether the edit request is a comment-only edit request or an edit request that includes an imperative statement by referring to the imperative statement/comment statement identification information, and the process proceeds to the next step according to the determination result. Transition. In the case of a request to edit only comment text, in the source program update process (step 2.5),
The source program is updated according to the contents of the edit request. In the case of an edit request that includes a command statement, an error message is output to the input/output device 4 in the error message output process (step 206), and the edit request is rejected until the complete date operation is completed. Step 206 is executed cyclically, and at the end, the state becomes END (step 208).

〔Effect of the invention〕

As explained above, the present invention allows editing of only comment statements and prohibits editing of instruction statements by distinguishing command statements and comment statements of a source program. This has the effect of automatically preventing erroneous changes to instruction statements during repairs.
