Abstract

PURPOSE:To execute the efficient processing of the work such as compiling and debugging by making unitarily an information item and source program data needed in the debugging and the maintenance work of a program. CONSTITUTION:Live source program data B3 are generated through a usual data editing function F1 with source program data B1 by a previous job step procedure B, and next, converted to an object module 5B of a machine language by a compiler B4. In such a case, slip image data B6 and B9 of processing result information outputted by respective processing steps B4 and B7 of the compiling and linking editing are temporarily kept to an external memory device. To the statement of respective data, the symbol, etc., to show a row number, an effective executing row number and the contents are given, and the source program data B3 and the data B6 and B9 are collated and made unitarily. Thus, the work such as the compiling and debugging of the source program can be efficiently executed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a source program translation and link editing device. More specifically, it has a function that collates additional information (compiler diagnostic messages, etc.) associated with translation (compilation) etc. with the source program and creates data that integrates the two, making it easier for programmers to debug and maintain programs. This invention relates to an aM translation and linkage editing device for source programs that facilitates translation.

(Prior Art) In a conventional source program translation and linkage editing device (a combiator that functions as a compiler and a linkage editor), the processing results of source program translation and linkage editing are outputted in a form.

Therefore, in compiling and debugging operations, programmers have to compare the output form with the source program data (or source program list).

In addition, the forms are generally stored and managed in such a way that the form itself or a form image is stored in an external storage medium, separate from the source program.

Figure 2 shows the case when using a conventional translation and linked editing device.
2 is a flowchart illustrating the configuration of a typical compilation and linked editing job step.

As shown in job step configuration A in Figure 2, the input source program data AI is translated into a machine language object module by the device's compiler (82), and then the device's linked editing function The basic program (subroutine) to be stored is incorporated (A4) and transformed into a load module ^5 which is a completed program.

In this case, the main steps for a programmer to compile and debug are as follows.

First, when a programmer creates a new program or modifies an already created or registered program, the programmer uses the source program/data editing function Fl (
After creating or modifying a source program statement using a data editing function (mainly using a CRT), job step 8 for compilation and linked editing is executed using the source program data as input.

Next, in order to check the execution results, the system's output queue reference function F2 displays the form contents on the CRT, or the system's printing device's form output function P3
This process of outputting a form and checking its contents is repeated many times until there are no errors in the source program statements. (Especially when developing a new program, this is done quite a number of times.) (Problems to be Solved by the Invention) Problems when compiling and debugging programs using conventional equipment are as follows.

■If an error occurs as a result of executing the compile and linked editing job according to the above steps, after understanding the content, refer to the source program data again.
It is necessary to search for and correct the error location, which is complicated and inefficient.

■When outputting the processing result form to a printing device and performing content V&verification (if the system does not have a function to refer to the output queue), the result will not be understood unless all the form contents are output. That's a huge waste of time and paper.

■ Compilation and linkage of programs that have been compiled and debugged '#Ja Collection When storing the resulting report, either store it as a report (paper) or store the output report image in an external storage device. , an extra space (location or content in a storage device ff1) separate from the source program data is required, and its management form is also complicated.

Therefore, it is an object of the present invention to extract ↑n information items required by a programmer in program debugging or maintenance work from the contents of each report output as a result of compilation and linked editing processing, into source program data. By centralizing, a) checking the results of compilation and linked editing processing, and if there is an error, understanding and correcting the location of the relevant statement and its contents, etc. can be performed using only the source program/data editing function; , b) When compiling or debugging, as much as possible,
C) Compiling and linked editing process result information to the source program
To provide a translation and linked editing device that can be integrated with data and centrally stored and managed; d) Compile or debug work efficiently.

(Means for Solving the Problems) As a result of repeated research to achieve the above-mentioned purpose, the present inventors have discovered that the results of compilation and linked editing and additional information such as associated diagnostic messages, together with the input source program. Provide the device with the ability to temporarily store it in an external storage device such as a magnetic disk, collate the stored source program with the temporarily stored additional information, and compose data that combines both. I came up with this idea.

Thus, the translation and link editing device according to the present invention stores the input source program in the program translation and link editing device that compiles and link edits the input source program into a machine language load module.
It also stores compilation results and compiler additional information, as well as external storage means for storing linked editing results and linked editing additional information. A function for assigning a line number and a valid execution line number, and b) Displaying the contents of a caution or warning for each statement of the source program whose valid execution line number had caution or warning information in the stored compilation information axis. C) Next, the content of the caution or warning is displayed for each statement of the source program of the valid execution line number where the caution or warning information was found in the saved linked W collection additional information. and d) a function of combining the source program, compilation additional information 1, and linked editing additional information to create a source program with additional information for editing and updating by a programmer. It is characterized by being prepared.

(Embodiment) The present invention adds a newly developed function for editing and updating processing result information of compilation and linked editing onto source program data in a job step for conventional compilation and linked editing processing. It is configured by giving it to AI.

The first diagram showing the processing step procedure B in the embodiment of the present invention.
This will be explained in detail with reference to the flowchart in the figure.

First, the source program data Bl that has been collated and unified (that is, edited and updated) with the additional information of compilation and linked editing by the previous job step procedure B.
Using the programmer, the normal data m'J1m function F1
Check and correct the contents of the source program. I will write about this later. (If you have created a new source program, please use the source program B3 described below.
Start with step B4, which compiles . ) Next, after the work by the programmer has been completed, the [1° Clear updated compilation and linked editing processing result information] is displayed on the previous source program data Bl.
(B2), pure (raw) source program data B
Generate 3. (This function is located at the step before the compile processing step.) Next, the compiler function of the device is used to perform compile B4 and convert it into a machine language object module B5. Furthermore, linkage editing (linkage editor) function performs linkage editing B7, incorporates subroutines stored in the device, and loads module B7.
Complete 8. These processing steps (84, B5, B
7.88) is the same as before.

However, in the apparatus according to the present invention, form image data B6 and B9 of processing result information (compile list and linked editing list) output in processing steps B4 and B7 of compiling and linked editing are stored in an external storage device. (
It has a function to write and store it as a temporary data set on a magnetic disk, etc.

The main (+'l flJ items exported by tIF are, for example, as follows.

Information items written on the compile list 1-86: ■ Contents of each statement in the source program and the statement number assigned to it, ■ 0FFSET information assigned to each statement in the program, ■ Compilation diagnostic messages (warnings) information), information message (note, t 1ri fG), (
These are messages regarding errors and the like. ), ■Options or parameter information specified for compilation, ■Information on the time required for compilation, etc.

Information items written on linkage & W collection list B9: ■Configuration of modules and subroutines after linkage editing fg
.

■Information on the completion status of the linked edit process, ■Information on the specified options or parameters and various instruction statements for the linked edit, and diagnostic messages (
warning information), caution information, etc.

The results and additional information data B6 and B9 accompanying the above-mentioned compilation and linked editing are provided by the normal compiler function and linkage editor (linkage editing) function, but in the present invention, these data are provided by magnetic It is stored in an external storage device such as a disk. Conventionally, information was simply printed as a form or generated information was partially referred to on a CRT or the like. Note that as the external storage device in the present invention, a refreshable storage medium (eg, a magnetic disk, a magnetic tape, etc.) that has been widely used in the past can be used.

Next, in processing step BIO, the apparatus according to the present invention compiles the source program data B3 and collates and unifies the data B6 and B9 output and stored in the linked ml, based on its functions.

That is, each statement in source program B3 has a line number (serial number of all lines) and a valid execution line number (C
Serial numbers are assigned only to lines containing execution instructions for the PU. In addition, among the compiler and linked editing additional information included in data B6 and B9, a symbol indicating the content is displayed in the preceding line with the valid execution line number where the warning information and caution information were found (certain alpha vents, etc. for each warning content, etc.) (in other words, edit the source program data).

The &W collection for the source program data is performed on a portion of the source statement other than the instruction description column position (column position that the compiler does not consider to be a valid statement) or on a comment statement.

As described above, the information items to be reflected on the source program data are edited, and the information items in the original source program data Bl are updated.

(This function is located in the step after the compilation and linked editing processing steps.) As a result, the source program data B after editing and updating
ll is source program data in which serial line numbers, valid execution line numbers, and symbols indicating the content of the above warning and caution information are added to attached statements, and further,
This is followed by a compilation list (including compilation results and additional compiler information) and a linked edit list (including linked editing results and additional linked editing information).

The programmer's work after the above process 810 is completed is as follows:
By reflecting all the results of the compilation and linked editing processing on the source program data all and Ill, a series of operations (from checking the contents to correction) is performed using only the direct program data editing function F1. In addition, content confirmation L2 and correction work include additions, changes, deletions, etc. provided in normal data editing function t+1.
This can be done quickly by using the search function.

(Effects of the Invention) In the device according to the present invention, the information outputted by the translation and linked editing processing (error information, information regarding the structure of the program, etc.) as described above is directly edited and updated on the source program data. The programmer can directly find and correct a source statement in which an error has occurred or an abnormal location when the program terminates abnormally by referring to the source program data.

Furthermore, this allows the storage format of output forms during translation and linked editing processing to be managed and saved using only the source program data.

To explain this point more specifically with an example that applies to the PL7+ language, it is possible to: ■Compile or debug work using only a single function (program/data editing function);
By simplifying the work, we were able to improve work efficiency by about 20%.

This is because various error information is displayed on the source program, so it is only necessary to look at the source program during dehasing. Conventionally, after printing an error information list, users searched for and corrected error locations in a source program while referring to the list.

■Approximately 60% of the forms output during compilation or debugging work could be reduced. That is, it is no longer necessary to print the compile list and linked '114m list, which were required in the past.

■By centrally managing and storing source program data and translation and linked editing processing results, programs that were previously stored in forms can be completely abolished. In other words, the 0FFSET information among various information, the configuration information of the completed program,
Since it is attached after the source program, you can simply save the source program data with this additional information, and when an error occurs during program execution (such as when an abnormal stop occurs).
The content of the abnormality can be deciphered by the information 11 (checked with the address at the time of stop in the OFFSET information).

In the past, there was no other way to save compiler information other than by printing.
